Senior Firmware Engineer, OpenBMC

What You’ll Do

To accelerate datacenter deployment and management, CoreWeave is expanding its firmware engineering team to focus on developing and maintaining OpenBMC-based firmware for our next-generation Baseboard Management Controllers (BMCs).

As a Senior Firmware Engineer, you’ll design, implement, and maintain embedded firmware features that enable secure, scalable, and reliable control across CoreWeave’s high-performance compute infrastructure. You’ll work independently on complex components, collaborate closely with cross-functional teams, and help set best practices for firmware quality and performance.

Key Responsibilities

• Design & Implement: Develop and enhance OpenBMC firmware in C++ for CoreWeave’s custom server platforms, contributing to key subsystems such as sensor management, power and thermal control, networking, and system monitoring.
• Integrate & Debug: Collaborate with hardware design, platform software, and reliability teams to integrate firmware with new hardware and validate performance across diverse environments.
• Optimize: BMC Performance and Harden Security
• Root Cause Analysis: Perform deep system-level debugging using tools such as GDB, JTAG, or logic analyzers to resolve cross-layer issues between hardware, firmware, and OS.
• Automate & Validate: Contribute to continuous integration and automated testing frameworks for OpenBMC build and validation.
• Document & Share: Maintain clear technical documentation and participate in design reviews to ensure consistency and maintainability across the firmware codebase.
• Collaborate Broadly: Partner with other ICs and technical leads across CoreWeave’s infrastructure engineering, hardware design, and operations teams to align firmware capabilities with platform and datacenter goals.
