Graphcore is a globally recognised leader in Artificial Intelligence computing systems. The company designs advanced semiconductors and data‑center hardware that provide the specialised processing power needed to drive AI innovation, while delivering the efficiency required to support its broader adoption.

The Firmware Engineering team develops platform management firmware responsible for monitoring, controlling, and servicing Graphcore’s AI compute infrastructure.

The team collaborates closely with hardware engineering, silicon teams, platform architects, and validation teams to deliver reliable firmware across server and rack‑scale systems.

• Lead the architecture and development of OpenBMC firmware for hyperscale server platforms.
• Enable hardware integration including power management, sensors, FRU inventory, and device management.
• Develop scalable manageability interfaces using D‑Bus, Redfish, PLDM, and MCTP protocols.
• Architect firmware security capabilities including Root of Trust, secure boot chains, and measured boot.
• Design firmware lifecycle management frameworks including multi‑component firmware updates with rollback protection.
• Develop telemetry and observability pipelines for fleet‑scale monitoring and diagnostics.
• Collaborate with silicon vendors and ODM partners from architecture through manufacturing ramp.
• Contribute to OpenBMC upstream projects and relevant industry standards.
• Mentor engineers and promote best practices in Yocto builds, CI/CD pipelines, and automated testing.
• Lead system‑level debugging across hardware and firmware in lab and production environments.

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Computer Science, or equivalent experience.
• 10+ years of experience developing BMC firmware for server or data center platforms.
• Strong expertise with OpenBMC including D‑Bus services, Yocto / Bit Bake, and platform integration.
• Strong programming skills in C/C++ and scripting languages such as Python or Bash.
• Experience with platform management protocols including Redfish, PLDM, SPDM, MCTP, and IPMI.
• Strong understanding of server hardware architecture including power delivery, thermals, sensors, and FRUs.
• Experience with hardware interfaces such as I²C, I3C, SPI, and PCIe.
• Experience building CI/CD pipelines for firmware development and validation.
• Strong debugging skills using tools such as JTAG, GDB, and logic analyzers.
• Experience developing OpenBMC for ARM‑based server platforms in hyperscale environments.
• Hands‑on contributions to the OpenBMC codebase or upstream community.
• Experience working with ODM/JDM partners across the platform lifecycle.
• Experience delivering firmware for large‑scale cloud deployments and fleet update infrastructure.
