As a Senior Software Engineer on the LiveIntent Real-Time Ad Serving team, you will design, develop, and own the business logic that powers programmatic advertising at scale — ad selection, targeting, frequency capping, budget pacing, and delivery optimization.

The real-time platform is built on C++ and Lua: C++ provides the high-performance server framework, while Lua implements the business logic layer. You will work primarily in Lua, developing and evolving the features that directly serve LiveIntent's product — ensuring advertisers get the best outcomes and publishers maximize their revenue. While we're open to candidates with experience in any backend language, a willingness to work with Lua is essential — we provide time and the right environment to get up to speed.

You will collaborate closely with Product, working on features that directly impact LiveIntent's customers — from ad targeting and delivery to reporting and optimization. This is a hands-on engineering role where your code runs in production handling billions of daily transactions.

This is a hybrid/remote role based out of our Berlin, Germany or Prague, Czech Republic offices.
