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.

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.
