Senior Software Engineer

About the role

Roblox is seeking a Senior Software Engineer to join their Release Engineering team, where you will be instrumental in building and maintaining the infrastructure that enables hundreds of engineers to deploy code safely to a platform serving tens of millions of concurrent players. This position sits at the intersection of developer tooling and production reliability, giving you direct influence over how quickly and confidently teams can ship high-impact features across every device that runs Roblox. You will work on backend services, automation systems, and C++ engine code to improve the entire release and experimentation pipeline. The role offers a unique opportunity to solve complex technical challenges at massive scale while directly impacting the experience of both internal engineering teams and the global Roblox player community. If you thrive in environments where your work on developer-facing infrastructure has immediate and measurable effects on end-user reliability, this position will be an excellent fit.
