Senior Software Engineer - Data | AppNexus Inc. | Portland, United States

Senior Software Engineer - Data (Portland) Engineering | Portland, United States

Send Jobvite

Team Description:
The AppNexus Data Platform team plays a key role in a technology company experiencing explosive growth. Our data pipeline processes 74 billion log records a day (more than 60TB of data) generated by our real-time bidding engines and ad serving platform. Data volume has rocketed over the past year and is continuing to increase. This data is used to generate aggregated analytics reports, update budgets, and drive optimization engines. Clients rely on analytics data to run their businesses, so it’s our job to provide excellent reporting to ensure they don’t lose money. We do all this while running against extremely tight SLAs. A budget is aggregated at 10-minute intervals, no matter how many more billions of transactions come in. To that end, we aim to provide real-time stats and budgeting to freeze campaign spending as close to real time as possible.

Consider some of the problems we tackle every day:

• Conversion attribution (or finding the needle in the haystack): In online advertising, we have to determine which events caused a particular conversion – or which ad impression caused a user to make a purchase. We hunt for the needle in a 150 billion-row “haystack,” and we do this millions of times every hour.
• Getting insight: Not only are we dealing with a growing body of data, but we also need to be able to process it rapidly, get insights and share it all with clients at whatever level of granularity they need.
• Processing data: We have built a platform that allows us to process data but many of our clients struggle to build tools that allow them to process our data directly. A key goal is to abstract out the functionality we have so our clients can benefit.
• New tools: We are always seeking new and better tools to help us meet challenges. For example, our data is so distributed that keeping it consistent globally is a major concern. To solve this problem, our team built Starfish—a monitoring tool that can self-heal any data discrepancies.

The most exciting part about working at AppNexus is the enormous potential for personal and professional growth. We operate in a continuous release cycle with 99.96% uptime, meaning new features are added weekly without ever taking our systems completely offline. Within weeks you will own a component of a system. We have too many large problems not to trust new developers with enormous responsibility. Join our team, and you have the opportunity to redefine an industry and your career.

Role description:
As a senior software engineer on  the data team, you would be working on and leading projects that are important to AppNexus’s success. Projects will involve processing big data streamed from thousands of ad-servers.  The goal is to collect, process and deliver results to consumers in a most efficient and reliable way. Running big data systems also involves production support. In this role, the candidate will be working with operations and data teams to help provide production support for our data systems.

Responsibilities:

• Ensure that jobs are being completed within our SLAs
• Take ownership of reducing the complexity of our data model
• Optimize our jobs to utilize Hadoop, HBase, Vertica resources in the most efficient way
• Ensure data consistency and the accuracy of our data
• Take ownership of adding new jobs to support client facing features
• Prioritize bug fixes with the goal of keeping the unreliability index close to 0
• Monitor and manage nagios services related to the ETL jobs schedule in our system. (reporting, billing, budget, optimization…)

Requirements:

• 5+ years of software engineering experience, developing software for distributed production systems 
• Fluency in Java, along with some experience in PHP or Python
• Familiarity with large-scale distributed data processing (i.e. Hadoop)
• Experience in start-to-finish deployment of large scale multi-TB data processing systems is a PLUS
• Strong understanding of RDBMS, SQL, no SQL alternatives Experience supporting production systems
• Passion for engineering and computer science around data
• Looks for novel and creative solutions to complex problems. Is a good collaborator and team player, with strong communication skills

What we look for:

• You are an independent thinker who is self-motivated and thrives in a fast-paced work environment.
• You are passionate about and thrive in a culture of learning and teaching – you are both open minded to others’ opinions and take opportunities to help and teach colleagues.
• You find new, creative solutions to complex problems and are passionate about high-performance computing and ultra-low latency.
• You love to develop and have a thorough understanding of server-side application development, scalable web services, query optimization, and database design.
• You are hands-on when designing applications and are comfortable coding off of not only a formal spec, but also a problem statement.
• You want to be part of an organization with a transparent and agile environment and a clear communication path between your team and the CEO where you can communicate freely and openly.

What's in it for you:

• Industry-changing work – build bold solutions to some of today’s most exciting technical challenges.
• Significant impact from your very first day thanks to our rapidly growing scale and agile engineering teams.
• Global presence – AppNexus has offices around the world: Manhattan, San Francisco, Seattle, Portland, London, Paris, Hamburg, Toronto, Sydney, and Singapore. Engineers are primarily based in Manhattan and Portland.
• Regular access to industry events - AppNexus hosts many technical meet-ups and speakers on site.
• We are a technology company at heart. Our founders can hold their own in architecture discussions with the team. Occasionally, our CEO even checks-in bug fixes to the ad server codebase.

• Free Food: Every office has fully-stocked kitchens featuring bagels each morning, as well as healthy and tasty snacks, drinks, and coffee throughout the day. Family Lunch Fridays – AppNexus provides free lunch for the company every Friday.

The AppNexus UI Team designs and constructs our client-facing product: AppNexus Console. Our challenge is building an intuitive and simple interface on top of our complex and extremely powerful systems. Our clients need front-end applications that enable them to easily operate and expand their businesses and efficiently buy and sell online advertising inventory with speed and confidence. Equally important is our visualization of our clients’ data, displaying everything they need to see in order to understand how their businesses are performing and where changes could be made to help them better perform. We work closely with our User Experience team, intelligently designing every feature of Console.

Consider some sample problems we tackle every day:

• Permissions-based UI: How do we build a dynamic UI that appears as a custom product for each client? We are shifting from building multiple UIs to building one UI with permissions-based features that are contract-dependent and appear differently based on which user is logged in. 
• Unified framework: With the introduction of Agile development practices and newly formed SCRUM teams, we need to build one unified framework that allows us to build consistent applications on each of our portfolio teams. We take advantage of object oriented design so that we only have to write the code once, test it once, and have it available to everyone on the team.
• Multiple, complex client needs: How do we design the UI to be simple and uncluttered while tailoring it to meet each unique client’s complex and diverse business needs? Our challenge is to create interfaces that are intuitive for first time users and yet allow “power users” to control (even micromanage) their businesses.

The most exciting part about working at AppNexus is the enormous potential for personal and professional growth. We operate in a continuous release cycle with 99.96% uptime, meaning new features are added weekly without ever taking our systems completely offline. By the end of your first day, you will already have committed code to mainline branch. Within weeks you will own a component of a system. We have too many large problems not to trust new developers with enormous responsibility. Join our team, and you’ll have the opportunity to redefine an industry.

We’re looking for someone who:

• Wants to be part of an organization with minimal bureaucracy and a clear communication path between our team and the CEO.
• Is hands-on when designing applications and is comfortable coding off of not only a formal spec, but also a problem statement.
• Writes blazing fast, reusable JavaScript and obsesses over page generation and rendering times.
• Has a passion for web development that manifests itself in a proven history of successful projects and the ability to write fast, accurate and scalable code.
• Has knowledge of server-side scripting languages, has experience consuming APIs, and has an opinion on when to do things client-side versus server-side.
• Looks for novel and creative solutions to complex problems.
• Is an independent thinker who is self-motivated and thrives in a fast-paced work environment.

What's in it for you:

• The opportunity to build relevant solutions to some of today’s most interesting technical challenges.
• The opportunity to have a significant impact from your very first day, thanks to our rapidly growing scale and agile engineering teams.
• Locations around the world: Manhattan, San Francisco, Seattle, Portland, London, Paris and Hamburg.
• Regular access to industry events–AppNexus hosts many technical speakers and meet-ups, always complete with free beer and pizza.
• And of course, competitive compensation, a relocation stipend and covered visa costs (if needed).
• Because our CEO is an industry recognized developer in his own right, your contributions to the company are recognized and rewarded.
• We are a technology company at heart. Our founders can hold their own in architecture discussions with the team. Our CEO even checks-in bug fixes to the ad server codebase on occasion.

The Other Perks:

• Great Technology: Any computer of your choosing. Most of our team uses retina displayed MacBook Pros, with multiple monitors for additional screen real estate.
• Free Food: Every office has fully stocked kitchens including healthy and tasty snacks, drinks, coffee, and bagels, each morning. Family Lunch Fridays – AppNexus provides free lunch for the company every Friday.
• Career Development: Annual budget for conferences and continuing education of your choosing.
• An Active Development Community: Participate in company sponsored Hackathons, Innovation days and events

The AppNexus web services team develops and maintains the RESTful API that allows our clients to programmatically manage their online advertisement business and receive billing and performance analytics from our platform. API services are consumed both internally and externally. We enable our UI engineers to build feature-rich web application / back office / auditing tools without making a single database connection, while enabling our clients to build their custom UI and perform real time integrations with other platforms. 
 
The API controls and centralizes read / write access to the business objects encapsulated in our MySQL database: enforcing rate limits, validating user inputs, and structuring data for our ad serving applications to interpret and execute.  Our system must be flexible and powerful enough to handle all of those tasks with very high peak usage – executing over 9,000 HTTP requests per minute! The API also exposes terabytes of ad serving, analytics, and performance data, equipping our clients to better analyze and optimize their campaigns.
 
Consider some of the problems we tackle every day:
 
• Overcoming scale challenges: How do we maintain speed, availability, and reliability in the face of our growing client base and exponentially growing number of objects and relationships in our system?
• Core developments:
• Leveraging mature open source technologies (such as Sphinx, Memcached, Solr, and primarily the LAMP stack) to increase uptime and reduce latency.
• Building our own API framework that is light, powerful, and specifically optimized for our tasks.
• Removing potentially asynchronous tasks from the critical path to keep response times low.
• Implementing our own distributed caching system, to speed up responses while maintaining consistent data between our data centers.
• Agile development: Our product is broken into portfolio teams who manage our client feature requests using SCRUM techniques. The API team’s challenge is managing operations across portfolio teams while consistently building an API that is fast and reliable.
 
The most exciting part about working at AppNexus is the enormous potential for personal and professional growth. We operate in a short release cycle (multiple times per month) and still maintain 99.96% uptime. You will have code running in production within a couple of weeks, and after just a few months, you can own a component of a system. We simply have too many challenges to not trust developers with enormous responsibility. Join our team, and you have the opportunity to redefine an industry and your career.
 
Who we are looking for:
1. You want to be part of an organization with minimal bureaucracy, open communication, and clear communication path between your team and the CEO and CTO.
2. You love to develop you have a thorough understanding of web development with any of the following languages: PHP, Java, Python, Ruby.
3. You enjoy solving complicated problems in novel ways.
4. You are an independent thinker who is self-motivated and thrives in a fast-paced work environment.
 
What's in it for you:
1. Industry changing development – build relevant solutions to some of today’s most interesting technical challenges
2. Significant impact from your very first day thanks to our rapidly growing scale and agile engineering teams.
3. A comfortable and relaxed office environment surrounded by passionate, driven colleagues.
4. Regular access to industry events – AppNexus hosts many technical speakers and meet-ups, complete with free beer and pizza.

Team Description:
The Batches Project is the infrastructure component that keeps the real-time decisioning systems running with the latest data. The data streams promise the latest in campaign, targeting, budget, and optimization data. We target having all of the data available within fifteen minutes of commit in the database. The team touches many different technologies, including: databases, web services, and system optimization.

Consider some of the sample problems we tackle every day:

• Data Stream Integrity: Our real-time budget problem requires pushing updates on millions of objects to thousands of machines, all while we observe strict SLA requirements.
• System Reliability: Develop automated systems to deal with some unique distributed system problems. We develop algorithms to deal with automated failover and data reconstruction. As with any large system, machines are constantly leaving and joining the cluster of available resources and our job is to ensure they have the data to operate at their full potential.
• Data Models: Data models will make or break companies. We design and implement data models that represent every component used in the real-time systems, as we're responsible for the sound and speedy delivery of the data. This requires the developer to understand the ins and outs of database design, database usage, and database refactoring. We will implement new ideas, take action upon these new ideas, and refactor them for extensions such as new use cases.

The most exciting part about working at AppNexus is the enormous potential for personal and professional growth. We operate in a continuous release cycle with 99.96% uptime, meaning new features are added weekly without ever taking our systems completely offline. By the end of your first day, you are committing code to mainline branch. Within weeks you own a component of a system. We have too many large problems not to trust new developers with enormous responsibility. Join our team, and you have the opportunity to redefine an industry and your career.

What we look for:

• You want to be part of an organization with minimal bureaucracy and a clear communication path between your team and the CEO, where you can communicate freely and openly.
• You are an expert with an object-oriented language, preferable Java.
• You have experience with real-time and distributed systems and possess a thorough understanding of computer science fundamentals.
• You are passionate about high performance computing and look for novel and creative solutions to complex problems.
• You are an independent thinker who is self-motivated and thrives in a fast-paced work environment.

What's in it for you:

• Industry-changing work – build bold solutions to some of today’s most exciting technical challenges.

Software Engineer - DevOps (New York) Engineering | New York, United States

Send Jobvite

Team Description:
The AppNexus DevOps team provides tools that enable easy, fast, and continuous evolution of the AppNexus advertising platform. Developers working on the applications that make up the advertising platform use DevOps’ tools to release their changes into the production system.  On a typical workday, around 20 developers will deploy their applications to production a total of 50 to 100 times.  Developers perform these deployments independently; the DevOps team is not concerned with their timing.  DevOps’ responsibility is that the tools are available, perform well under high load, and are easy to use.
Additionally, the DevOps team has responsibility for providing automated testing environments.  These environments run the same code as the production system, and the instances contained within them can be upgraded same as the production instances.  However, these environments do not respond to ad requests from the actual external publishers.  The use-cases for testing environments include reproducing production bugs, running cross-application platform tests, and aiding per-application development and QA.  For much of 2014, DevOps has been focused on working with our Engineering, Operations, and Services teams to increasing the capabilities of our automated testing environments.
Consider some of the sample challenges we tackle every day:

• High Visibility: Managing the AppNexus infrastructure has an impact across the entire company, including the executives, who depend directly on our team’s success to do their jobs.
• High Volume: Clients depend on AppNexus to make money.  When certain parts of our system go down, our clients may stop making money entirely until the components come back online.  Thus, our tools must be able to sustain global deployments at 100% concurrency across thousands of servers.
• One of the most exciting parts about working at AppNexus is the enormous potential for personal and professional development. The fast growth of the programmatic advertising market, plus the even higher growth of AppNexus means there is a constant stream of problems that require innovative thinking and innovative software development.  Per engineer, the amount of responsibility is exceedingly high, which means each engineer has ample opportunity to make important decisions, and learn from the successes and failures of those decisions.

Role description:
We’re looking for an innovative engineer interested in building and enhancing the components that our advertising platform relies on.  As a DevOps Senior Software Engineer, you will be responsible for leading the design and implementation of improvements made to this system.

Requirements:

• 5+ years building and managing large-scale systems with at least 99.99% uptime requirement
• 5+ years writing software for production systems.
• Experience mentoring fellow software engineers
• Familiarity with automation tools, such as Puppet and Chef
• Experience working with customers to understand their needs, and present solutions that solve their problems

What we look for:

• You want to be part of an organization with a transparent and agile environment and a clear communication path between your team and the CEO where you can communicate freely and openly.
• You are hands-on when designing applications and are comfortable coding off of not only a formal spec, but also a problem statement.

Send Jobvite

Team Description:
The AppNexus Data Platform team plays a key role in a technology company experiencing explosive growth. Our data pipeline processes 74 billion log records a day (more than 55TB of data) generated by our real-time bidding engines and ad serving platform. Data volume has rocketed over the past year and is continuing to increase. This data is used to generate aggregated analytics reports, update budgets, and drive optimization engines. Clients rely on analytics data to run their businesses, so it’s our job to provide excellent reporting to ensure they don’t lose money. We do all this while running against extremely tight SLAs. A budget is aggregated at 10-minute intervals, no matter how many more billions of transactions come in. To that end, we aim to provide real-time stats and budgeting to freeze campaign spending as close to real time as possible.

Consider some of the problems we tackle every day:

• Conversion attribution (or finding the needle in the haystack): In online advertising, we have to determine which events caused a particular conversion – or which ad impression caused a user to make a purchase. We hunt for the needle in a 150 billion-row “haystack,” and we do this millions of times every hour.
• Getting insight: Not only are we dealing with a growing body of data, but we also need to be able to process it rapidly, get insights and share it all with clients at whatever level of granularity they need.
• Processing data: We have built a platform that allows us to process data but many of our clients struggle to build tools that allow them to process our data directly. A key goal is to abstract out the functionality we have so our clients can benefit.
• New tools: We are always seeking new and better tools to help us meet challenges. For example, our data is so distributed that keeping it consistent globally is a major concern. To solve this problem, our team built Starfish—a monitoring tool that can self-heal any data discrepancies.
