You will:

Build and scale test automation infrastructure: Design, implement, and evolve the frameworks, runners, orchestration services, workflow integrations, and supporting infrastructure that power reliable testing across Roblox's supported platforms

Advance the AI-native test lifecycle: Develop intelligent tooling that improves test authoring, selection, execution, maintenance, and failure triage, using AI to reduce manual effort and make testing more accessible and effective

Develop test orchestration and intelligence: Build systems that connect test planning, test selection, execution, and failure analysis, enabling more efficient use of test infrastructure and faster feedback to engineers

Improve test reliability and debugging: Build tools and services that improve test stability, observability, failure diagnosis, and maintenance across a large and evolving test ecosystem

Shift quality earlier in the development lifecycle: Integrate automated quality checks and actionable test feedback into development and CI/CD workflows to help teams identify and resolve issues earlier

Drive projects end to end: Take ownership of technical initiatives from problem definition, design, and implementation through production deployment, adoption, measurement, and continuous improvement

Collaborate across engineering: Partner with application, platform, QA, infrastructure, and developer productivity teams to develop scalable solutions that address the needs of engineers across Roblox
