Principal Software Engineer - DevEx & CI/CD

As a Principal Software Engineer on the Engineering Acceleration team, you will define and execute the long-term technical vision for Roblox's core developer platform, serving 2,000+ internal software engineers. You will transform Roblox's source code search, storage, code review, continuous integration (CI), and artifact management infrastructure for the next decade of scale. In this high-impact role, you will integrate cutting-edge AI-powered development tools and intelligent code review workflows into the daily engineering lifecycle—eliminating developer friction and setting the architectural bar for engineering productivity across the entire organization.

Key Responsibilities

• AI-Powered Developer Experience: Integrate generative AI, automated code assistance, and intelligent developer tooling into engineers' daily workflows to accelerate code production and reduce toil.
• End-to-End Infrastructure Architecture: Design, build, and evolve high-scale developer services—spanning local CLI tooling, internal web applications, reusable CI workflows, and telemetry metrics toolchains.
• Company-Wide Technical Leadership: Drive major company-wide initiatives that optimize source code management and build/CI tools, establishing technical standards across engineering teams.
• Multi-Cloud & Tooling Integration: Architect integrations across 1st-party microservices and 3rd-party developer platforms (e.g., GitHub, GitHub Actions, Artifactory, AWS, Kubernetes, Nomad).
• Mentorship & Engineering Culture: Mentor senior staff and lead engineers across Roblox, cultivating a strong culture of architectural rigor, technical excellence, and developer-focused empathy.
