Senior Firmware Engineer, OpenBMC

What You’ll Do

To accelerate datacenter deployment and management, Core Weave 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 Core Weave’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.

• Design & Implement: Develop and enhance OpenBMC firmware in C++ for Core Weave’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 Core Weave’s infrastructure engineering, hardware design, and operations teams to align firmware capabilities with platform and datacenter goals.

• Experience: 4+ of professional experience in firmware or embedded systems development, including direct work with Linux-based OpenBMC firmware.
• Education: Bachelor’s degree in Computer Engineering, Electrical Engineering, Computer Science, or a related field.

• Proficiency in C/C++ for embedded systems.
• Hands‑on experience with OpenBMC
  , Yocto Project
  , and embedded Linux environments.
• Familiarity with hardware interfaces and protocols (I2C, SPI, UART, GPIO, IPMI, DMTF Redfish)
• Experience with hardware bring‑up
  , board‑level debugging, and sensor integration.
• Comfort with Linux kernel configuration, device trees, and BSP‑level integration.
• Working knowledge of source code control system such as Git.
• Comfort with debugging tools such as GDB, JTAG and debugging over serial or remote consoles.
• Basic scripting skills in Python or Bash for build automation and validation.

• Strong problem‑solving and analytical thinking; able to break down complex system‑level issues.
• Communicates effectively with peers across hardware, firmware, and operations teams.
• Self‑driven with a focus on delivering high‑quality, maintainable code.
• Thrives in a fast‑paced environment and balances multiple priorities effectively.

• Experience developing CI/CD pipeline for firmware builds and regression testing.
• Exposure to large‑scale datacenter or HPC environments.
• Contributions to open‑source firmware projects or upstream Linux development.
