Job Summary

Lead the technical direction for GPU compute at Roblox as a Principal Software Engineer, tackling large-scale challenges in GPU and AI accelerator infrastructure across global data centers and cloud environments. This role offers the chance to shape the future of human interaction by optimizing critical compute capabilities.

About this job

As a Principal Software Engineer on the Compute team, you will be the technical anchor for Roblox's GPU and AI accelerator capabilities. This role focuses on machine management, ensuring GPU hosts are production-ready, healthy, and reliable for various workloads. You will own scaling challenges, from driver and firmware management to GPU health and performance across data centers and cloud environments.

Requirements

- 10+ years of experience building and operating large-scale distributed systems and infrastructure. - Deep, hands-on GPU expertise at the machine management layer and above: GPU host provisioning, driver and firmware lifecycle, GPU health and reliability, and the realities of running accelerators in production. - A track record as an expert for compute, not just fleet management, with the scars to prove you have scaled GPU or accelerator infrastructure that other teams depend on. - Strong proficiency in Go or other well-structured programming languages. - Experience operating GPU and AI workloads in production, including familiarity with CUDA, GPU scheduling, and high-performance networking (NVLink, InfiniBand, RoCE). - Familiarity with Kubernetes for GPU workloads and with bare-metal concepts (firmware, BMC/IPMI/Redfish, OS imaging) is a strong plus. - A history of being the anchor expert that an organization relies on for its hardest GPU and compute problems, and the leadership to up-level the engineers around you.
