Sr. C/C++ Software Engineer, AppNexus, NYC

We are seeking world-class, senior software engineers (who are still very hands-on) to work on our state-of-the-art ad serving platform. Our extremely successful platform is very large-scale, globally distributed across 3 data centers, service oriented, and event driven. We handle a hundred thousand ad serving requests per second (100s of billions per month), and respond with very strict latency requirements. In addition, we data-mine a warehouse of 10 TB+ of data (and growing!), to generate some very sophisticated analytics/optimization that drive decisions behind the ad-serving process.

We expect a dramatic increase in the data rates and volumes in the near future and even more stringent latency requirements from our partners, and so need to make significant additions to our team to help evolve our platform to the next generation.

The environment is very fast paced. Successful candidates must be comfortable in making architecture decisions for a platform which is changing daily, all the while clients are actively using the system. We believe in an agile and incremental software development and particularly value simple solutions to complex problems. We also look for ability to diagnose a problem across the entire software and hardware stack rather than just debug a piece of code. Given the uptime constraints on our platform (24/7, 99.99%), operational maintainability of our software is of utmost importance.

The exact domain experience is less of a concern for us than the ability to fit into the above general profile. We are open to candidates from areas like telecom and automated trading/finance.


* 7+ years developing production-level software
* Outstanding architecture, programming and debugging skills in C/C++
* Excellent problem solving skills
* Experience with real time, low latency, high throughput and large scale systems
* Experience with data structures, algorithms, profiling and performance optimizations


* Experience with kernel optimizations and the TCP/IP stack

Why AppNexus?

If you're driven, smart, and dynamic, and want to work with other people who fit that same description, look no further. Our team, including our senior leadership, is composed of some of the most respected people in the industry. Our passion for our work carries into our hobbies, ranging from fashion design to break-dancing to sailing. It seems to be no accident that we were named one of the Top 100 Private companies on the East Coast (AlwaysOn), as well as one of New York City's 10 Hottest Tech Startups (amNY). If you think you can keep up, don't worry if you've missed a few bullet points. We want to talk to you!

That still not exciting enough? How about the $50 million dollars in funding we just received? http://appnexus.com/news/press-releases.php
