SoC Engineer

About the team

OpenAI’s Hardware organization develops custom silicon and systems for advanced AI workloads. Our first-party accelerator team works across chip architecture, design, software, and systems to build the computing platforms that power frontier models. We are a small, dynamic team that values technical breadth, hands-on engineering, and creative approaches to building complex hardware.

About the role

We’re looking for a SoC Engineer to help architect, design, and integrate OpenAI’s first-party AI accelerators. You will build the processor, interconnect, I/O, and platform infrastructure that connects our accelerator designs into complete, functional systems.

This role combines architectural judgment with hands-on implementation. You’ll work closely with design, architecture, verification, and software teams throughout development, from defining subsystem requirements and integrating IP to pre-silicon validation, silicon bring-up, and post-silicon debug. You should enjoy stretching across domains, rolling up your sleeves, and doing the work needed to make a complex system function end to end.

In this role, you will

• Define and implement SoC architectures spanning embedded processors, AMBA interconnects, peripheral subsystems, PCI Express, Ethernet and die-to-die interfaces.

• Develop the microarchitecture and RTL design of subsystems supporting I/O and SoC functionality.

• Integrate Arm Cortex-M and Cortex-A processors, AXI/APB fabrics, and
