Were on a mission to connect a billion people with optimism and civility and looking for amazing talent to help us get there.

A career at Roblox means youll be working to shape the future of human interaction solving unique technical challenges at scale and helping to create safer more civil shared experiences for everyone.

As a Principal Software Engineer on the Fleet Management team you will lead the systems that provision and rebuild Robloxs global fleet across bare metal and team owns provisioning and MAPI the global Machine API that turns raw capacity into production-ready infrastructure in minutes across hundreds of thousands of machines on-prem and cloud environments including new GPU and new AI will shape the technical direction for this critical compute platform and unify diverse hardware and environment-specific workflows behind MAPI and drive large-scale maintenance operations like firmware updates and hardware tuning.

You will:

• Lead the Machine Bootstrap pod in building and evolving provisioning and fleet management at massive scale.
• Architect and extend MAPI the unified Machine API that abstracts bare-metal GPU hosts and cloud instances behind a single global interface.
• Ship fleet-wide maintenance operations (BIOS updates firmware updates configuration changes) to hundreds of thousands of machines through MAPI.
• Drive best-in-class provisioning performance minutes to fully rebuild a machine from scratch.
• Evaluate and integrate new hardware platforms including GPU servers and AI accelerators into the provisioning pipeline.
• Collaborate across Compute Networking and Cloud teams on the full machine lifecycle from rack-and-stack to production.
