Send Jobvite

Team Description:
Each day, billions of impressions and millions of dollars are transacted on the AppNexus platform.  The Billing Team is responsible for making sure every penny from every transaction is accounted for and credited and debited to and from the proper parties.  It’s not as easy as it sounds, because each party and counterparty has their own contract terms.  We’re also responsible for converting the massive set of transactions into consumable formats for various internal and external systems, such as customer invoice PDFs, our ERP and GL, Salesforce.com, and internal databases.
Our current system (written in Python) has served us well, but as our business has expanded, so have the demands on our system.  We’re looking to overhaul this system end-to-end, and want your help.
If you’re curious about how all the money behind online advertising moves, but you’re also all about writing precise, testable, and readable code, you just might fit the bill, pun intended.
Role description:
As a Software Engineer on the Billing Team, you will:

• Work on a small, growing, business-critical team with other focused, intelligent, and talented people
• Help architect and build an entirely new billing system, using whatever technologies make the most sense
• Maintain our current system while the new one is being built
• Gain an in-depth understanding of the business of an online advertising giant – each week you’ll probably learn something new about the business and how we run it 

Responsibilities:
The Software Engineer on the Billing team will:

• Understand our pricing model and pricing terms
• Help design and implement a system that provides billing and revenue data for internal and external use
• Debug, troubleshoot, and refactor existing code in order to eliminate revenue-impacting bugs
• Write readable, testable code
• Automate the flow of large amounts of financial data with consistency and accuracy
• Work in an agile process – be able to break down work into bite-size chunks and communicate this to the team
  

Requirements:
Technical Requirements:

• Degree in Computer Science
• Python, or similar dynamic language
• Java, or similar strongly typed language
• Experience writing and reading SQL queries

• Experience working on a *nix system
• A demonstrated ability to learn new languages and technologies

Other Requirements:

• We’re not looking for just a programmer, but someone with technical skills and a deep passion for understanding how businesses make money, how they price, etc. 
• A love of problem-solving, analytical thinking, and learning
• No MBA required

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.
• You 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.
• 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.

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.
• Competitive benefits package, with plan options to design the coverage to fit your life — highly subsidized health, dental and vision insurance coverage from day one, fully vested employer-matched 401(k), company-seeded health savings accounts, back-up childcare, pet insurance, and much more.
• 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.

The other perks:

• Great Technology: Any computer of your choosing. Most of our team develop using retina displayed MacBook Pros, with multiple monitors for additional screen real estate.
• 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.
• Career Development: AppNexus offers a variety of internally-developed learning sessions, customized workshops, and robust professional development programs to help you strengthen your potential, develop new skills, grow your career and make greatness happen at AppNexus. 
• An Active Development Community: Participate in company sponsored Hackathons, Innovation days and events.

Send Jobvite

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.

Senior Software Engineer – User Interface (New York) Engineering | New York, United States

Send Jobvite

Team Description:

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 business 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 business is 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 allows “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 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.

• You have taken ownership of large software projects in the past and are looking for an opportunity to take on even more responsibility.
• 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 hands-on when designing applications and are comfortable coding off of not only a formal spec, but also a problem statement.
• You write blazing fast, reusable JavaScript and obsess over page generation and rendering times.
• You have a passion for web development that manifests itself as a proven history of successful projects and the ability to write fast, accurate, scalable code.
• You have knowledge of server-side scripting languages and have experience consuming APIs and have an opinion on when to do things client-side versus server-side.
• You 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.

Senior Software Engineer - Data (San Francisco) Engineering | San Francisco, 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

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

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
