Senior Hardware Engineer - Infrastructure

Every day, tens of millions of people come to Roblox to explore, create, play, learn, and connect with friends in 3D immersive digital experiences– all created by our global community of developers and creators. At Roblox, we’re building the tools and platform that empower our community to bring any experience that they can imagine to life. Our vision is to reimagine the way people come together, from anywhere in the world, and on any device.

We’re 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 you’ll 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 member of the Infrastructure Foundation Hardware Engineering team, you will help develop and validate next-generation server platforms that power a reliable, high-performing, and cost-efficient infrastructure at scale.

You will work across platform bring-up, firmware qualification, hardware validation, fleet integration, and performance optimization to support large-scale production deployments. You Will: Bring-up Sustaining: Drive key aspects of the hardware development lifecycle, including feasibility studies, hardware bring-up, validation, deployment, and ongoing production support. Platform Optimization: Perform platform integration, performance characterization, and system-level debugging across compute infrastructure, focusing on hardware optimization, driver tuning, and thermal/power efficiency.

Hardware Validation: Develop and execute rigorous evaluation and stress-testing strategies for server platforms to ensure reliability and performance under production-scale workloads. Firmware Fleet Enablement: Support BIOS/BMC firmware qualification, hardware health monitoring, and automation tooling for firmware deployment and lifecycle management. Vendor Cross-Functional Collaboration: Partner with hardware vendors and internal infrastructure teams to investigate component- and system-level failures across hardware, drivers, firmware, and kernel layers.

You Have: Experience: 5+ years of hardware engineering, system architecture, or infrastructure validation experience. Education: BS/MS in Electrical Engineering, Computer Engineering, Computer Science, or equivalent practical experience. Technical Knowledge: Strong understanding of Linux-based server environments, modern data center technologies, and server architecture including PCIe, NVMe, Ethernet/InfiniB and memory subsystems, and accelerator-based platforms.

Testing Skills: Hands-on experience testing and validating CPU, Memory, Storage, and high-speed networking subsystems in a Linux environment. Programming: Proficiency in Python, Go, or Bash for developing hardware validation tools and automation scripts. System Debugging: Strong experience debugging complex server issues remotely, including analysis of kernel logs, hardware registers, and bus-level traces/captures.

GPU Architectures: Familiarity with GPU platforms, AI accelerators, or high-performance compute (HPC) systems is a plus. You Are: A Problem Solver: Decisive and effective at tracking hardware issues from identification through to fleet-wide resolution. A Communicator: Excellent oral and written communication skills; able to translate complex hardware constraints into actionable insights for software teams.

Collaborative: Strong interpersonal skills with the ability to lead cross-functional projects with Data Center Ops, Supply Chain, SRE, and external vendors. Adaptable: Willing to travel occasionally to data centers or vendor sites to oversee hardware deployments or "first-of-a-kind" builds. For roles that are based at our headquarters in San Mateo, CA: The starting base pay for this position is as shown below.
