Senior Firmware Engineer, BIOS

What You’ll Do

As a Senior Firmware Engineer, you will drive the development and evolution of our UEFI/BIOS ecosystem and influence future server architecture decisions. Leveraging deep expertise in x86 and ARM64 architectures, you will architect secure, scalable firmware solutions tailored for CoreWeave's high-performance AI infrastructure. You will own complex technical challenges, lead cross-functional initiatives with hardware and security teams, and partner with key silicon vendors to optimize our custom server stack for next-generation compute capabilities. You will architect and refine mission-critical systems on state-of-the-art server platforms and next-generation silicon, exercising end-to-end ownership of core firmware components from conceptual design through global deployment, while collaborating with industry-leading innovators to define the future of high-performance cloud computing.

Some of what you’ll work on:

• Architect and implement advanced UEFI/BIOS features optimized for large-scale server deployments.
• Diagnose and resolve intricate firmware vulnerabilities and bugs using ITP, JTAG, and hardware debuggers.
• Streamline platform initialization and boot sequences to enhance system responsiveness and efficiency.
• Integrate robust secure boot protocols and hardware-root-of-trust mechanisms to safeguard firmware integrity.
• Engineer and maintain critical Power-On Self Test (POST) logic for diverse hardware configurations.
• Design seamless remote firmware update and recovery pipelines for fleet-wide reliability.
• Lead technical collaboration on board bring-up, hardware validation, and platform stabilization efforts.
