Software Engineer, Performance Automation Platform

Responsibilities

About this team We own the Effect SDK powering TikTok's camera and creation experience - the system behind every filter, AR effect, and visual effect used by hundreds of millions of creators every day. This role sits at the business architecture layer of a self-developed rendering engine, partnering closely with rendering, algorithm, and camera pipeline teams to deliver smooth, low-power effect experiences across a massive range of mobile devices. Responsibilities - Maintain and evolve the effect performance automation platform covering benchmarking, regression prevention for both effects and SDK features, effect-vs-effect comparison, performance prediction, and batch optimization pipelines. - Design and implement new platform capabilities that let effect creators and SDK engineers ship higher-quality, better-performing effects and SDK features. - Own the physical device farm - from device scheduling and task orchestration to stability, observability, and capacity planning. - Build tooling and dashboards that turn raw performance signals (FPS, CPU/GPU, memory, power, thermal) into actionable insights for effect producers, algorithm, and SDK teams. - Keep the system reliable at scale: CI/CD for the platform itself, device farm health, test throughput, and result reproducibility. - Partner with the Rendering engine, and algorithm teams to close the loop between "problem detected on the platform" and "fix landed in production."

Qualifications

Minimum Qualifications - B.S. or M.S. in Computer Science or related field; proficient in Python and/or JavaScript/TypeScript, and able to read and reason about C/C++ code. - Solid fundamentals in OS, networking, and distributed systems; comfortable building services that run 24/7. - General awareness of mobile development concepts (iOS and/or Android) - enough to understand what "performance" means on a phone and why a given metric matters. - Ownership mindset, strong communication skills, and willingness to collaborate across client, algorithm, and infra boundaries. Preferred Qualifications - Experience building automation platforms, CI/CD systems, or engineering productivity tooling at scale. - Hands-on experience with mobile device farms / lab management or an interest in operating physical infrastructure. - Familiarity with mobile performance metrics and profiling tools (Perfetto/Systrace, Xcode Instruments, Android GPU Inspector, power monitors). - Frontend skills (React / Vue) for building internal tooling dashboards; experience building AI Agent; background in game engines, graphics, or AR is a plus for understanding the domain.
