The Consumer App Foundation team is looking for a Senior Software Engineer to improve Roblox performance across our supported platforms. Our platform is used by over 150M people daily. You will work primarily in cross-platform C++ Roblox game engine code, partnering with teams across the company to identify bottlenecks, ship measurable improvements, and prevent regressions over time.

Our team is responsible for the end-to-end performance of the Roblox client on Android, iOS, macOS, Windows, Xbox, Playstation and TV. We tackle the platform’s most difficult technical constraints, ranging from speed and responsiveness to efficiency and stability, to ensure a high-performance experience across all of our devices and platforms.

Collaborate closely with stakeholders across Engineering, Product, and Design to evaluate technical tradeoffs, align on company-wide priorities, and execute smooth rollout plans.
Drive deep technical impact by diving into complex, unfamiliar codebases, taking ambitious projects from greenfield MVP to production-grade, and mentoring peers on performance best practices.

You have:

3+ years of experience writing high-quality, performant C++ code in large, complex codebases
A proven track record of building reliable measurement, monitoring, or regression prevention systems.
The ability to autonomously navigate complex, ambiguous systems and deliver stable, production-grade software.
Exceptional communication skills to discuss technical trade-offs with both engineering peers and cross-functional partners.

Hands-on experience with on-device profiling (iOS and/or Android) to find and measure optimization opportunities.
