Job Summary

We are seeking a Senior BMC Firmware Engineer to develop and support next-generation Baseboard Management Controller (BMC) firmware for Graphcore's AI server platforms.

This role will focus on building secure, scalable, and cloud-ready platform management infrastructure across hyperscale AI systems. The successful candidate will contribute to OpenBMC firmware development from hardware bring-up through production deployment, enabling advanced telemetry, firmware lifecycle management, and platform orchestration capabilities across large-scale AI infrastructure.

The ideal candidate combines strong expertise in OpenBMC, Linux-based firmware development, server platform architecture, and low-level hardware integration with excellent collaboration and problem-solving skills.

The Team

The Systems Firmware and Platform Engineering teams are responsible for delivering the foundational firmware infrastructure powering Graphcore's AI compute systems.

The team works closely with silicon engineering, server platform architects, hardware engineering, ODM/JDM partners, and data center operations teams to design, develop, validate, and deploy scalable platform management solutions for next-generation AI infrastructure.

This collaborative environment enables rapid innovation across server management, telemetry, firmware security, and fleet-scale deployment technologies while supporting the operational reliability of Graphcore's AI platforms from early bring-up through production deployment.

Responsibilities and Duties

• Develop and maintain OpenBMC firmware for cloud-scale ready server platforms, from hardware bring-up to production deployment. Strong hands-on experience with the OpenBMC stack is required.
• Enable hardware integration including power, sensors, FRU inventory, and PCIe/NVLink device management.
• Build and maintain manageability interfaces using D-Bus, Redfish, PLDM, and MCTP.
• Support firmware security features including Root of Trust, secure/measured boot, and SPDM attestation.
• Contribute to multi-component firmware update frameworks with A/B redundancy and rollback protection across BMC, BIOS, GPUs, and NICs.
• Develop telemetry and observability capabilities for platform monitoring and diagnostics.
• Collaborate with silicon vendors and ODM partners throughout platform development and manufacturing ramp.
• Contribute to OpenBMC upstream and industry standards initiatives including DMTF, Redfish, and SPDM.
• Support CI/CD infrastructure, Yocto builds, automated testing, and firmware validation workflows.
• Perform system-level debug across hardware and firmware in lab and production environments.
• Contribute to and support lab development, maintenance, hardware handling, and logistics activities.

Candidate Profile
Essential

• Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, Computer Science, or equivalent experience.
• 6+ years of BMC firmware development for server or data center platforms.
• Deep expertise in OpenBMC, including D-Bus services, Yocto/BitBake, and platform integration.
• Strong programming skills in C++, C, Linux kernel/user-space, and scripting languages including Python and Bash.
• Experience with Redfish, PLDM, SPDM, MCTP, and IPMI.
• Solid understanding of server hardware architecture including power systems, thermals, sensors, and FRUs.
• Experience with system interfaces and buses including I²C, I3C, SPI, PCIe, and related platform control interfaces.
• Experience with BIOS-BMC interactions, telemetry, RAS, and firmware lifecycle management.
• Experience building CI/CD pipelines for firmware development and validation.
• Strong system debugging skills using JTAG, GDB, and logic analyzers.
• Familiarity with firmware security concepts including Root of Trust, secure boot, and signed firmware updates.
• Familiarity with hardware schematics and logical hardware debugging methodologies.

Desirable

• Experience developing OpenBMC for ARM-based server platforms in hyperscale environments.
• Hands-on experience with the OpenBMC codebase, including platform bring-up and upstream contributions.
• Experience working with ODM/JDM partners across the platform lifecycle.
• Experience delivering firmware for large-scale cloud deployments and fleet update infrastructure.
