Job summary

Roblox is seeking a technical lead for GPU hardware within the Infrastructure Foundation Hardware Engineering team in California. You will own the full lifecycle of GPU hardware from architecture through firmware qualification to fleet integration and performance tuning.

You will collaborate across teams to optimize real-time rendering and AI workloads at scale. The role requires 5+ years in GPU architecture or HPC, strong Linux/driver debugging skills, and travel as needed.

Qualifications

• BA/BS in Electrical Engineering, Computer Engineering, or related field or equivalent practical experience.
• 5+ years hardware engineering experience focused on GPU architecture or HPC systems.
• Understanding of PCIe fabric, NVLink, InfiniBand, and liquid cooling for high-TDP hardware.
• Testing and validating CPU, memory (HBM/DDR5), storage (NVMe), and networking subsystems in Linux.
• Proficiency in Python, Go, or C++ for automation and tooling.
• Ability to debug server issues remotely, including kernel logs and hardware registers.
• Willingness to travel occasionally to data centers or vendor sites.

Responsibilities

• Prototype GPU-accelerated hardware platforms and ensure integration with high-density compute nodes, interconnects, and firmware.
• Drive integration, performance testing, and debugging of GPUs in the fleet with hardware-level optimizations.
• Develop evaluation and stress-testing strategies for GPU-heavy server platforms for real-time rendering and AI inference.
• Lead firmware qualification (BIOS/BMC) and troubleshooting, and build automation for GPU health and updates.
• Provide guidance to hardware vendors and lead investigations into component-level failures across hardware, driver, and kernel layers.
• Build and maintain Grafana/Prometheus monitoring for GPU metrics like HBM, throttling, and PCIe bandwidth.
