Team Lead, Senior Software Engineer Real Time Platform (Distributed Systems Golang, C/C++, or Java)

Senior Software Engineer – Team Lead, Real Time Platform

The AppNexus Platform was built upon the foundation that we could help our clients buy and sell media in the most effective and efficient way possible. In the past 3 years, we've grown from processing 300k QPS to over 5 million QPS for an approximate total of 100 billion requests per day.

Building on the foundation of the AppNexus platform, we released Prebid Server as an open source header bidding solution. Our Engineering team that supports Prebid has a history of providing support to a large base of publishers – actively providing new and innovative features and functionality. Be prepared to take on the challenges of scaling this new real time business platform and working with a community of engineers committed to building the best in class offerings.

As a Team Lead working on our Real Time Platform, you’ll have the opportunity to quickly see the impact of your contributions to our clients and end users. You will spend your half your time writing code and the other half leading a team of Engineers to solve problems that face online publishers in a variety of areas.

Consider some of the problems you will work on:

  • Large-scale distributed systems: Design, maintain and build systems at scale. Our Platform requires pushing updates on millions of objects to thousands of machines using our custom caching solution all while observing strict SLA requirements.


  • Interesting algorithmic problems: Use the latest research and techniques to make full use of the underlying hardware and instruction sets, utilizing things like lock-free data structures and intelligent thread design to optimize revenue, memory footprint, and overall algorithmic efficiency.


  • Collaborate with Open Source: Contributing to a growing open source project and leverage the community to continue growing and scaling the project while increasing quality and bringing innovative features to market.


  • Prototype to Production: As a bold company where Engineers work right alongside Product Managers, we go from iterating & validating a new concept with beta customers to developing it into production-quality code.
