Job description

Firmware Engineer 5

Duties of Position

• Architect Open BMC Solutions: Lead the design and implementation of Open-BMC distributions tailored for hyper scale hardware, including hardware abstraction layers and D-Bus interfaces. Responsible for defining the overall system architecture, choosing the security framework (Root of Trust, SPDM), and ensuring the BMC integrates seamlessly with BIOS and cloud-scale fleet management.
• Hyper scale Collaboration: Partner with Hardware and Systems teams to define firmware requirements for OCP (Open Compute Project) compliant servers and storage enclosures.
• Modern CI/CD Integration: Drive automated testing and continuous integration workflows for firmware, ensuring high-velocity deployments without sacrificing stability.
• Security & Root of Trust: Implement and maintain platform security features, including Secure Boot and hardware Root of Trust (RoT) integration.
• Full-Stack Ownership: Manage firmware development from low-level boot loaders (U-Boot) to high-level management APIs (Redfish/gRPC).
• Production Support: Provide expert-level debugging for critical issues identified in hyper scale data centre, utilizing remote telemetry and crash dump analysis.
• Participate in firmware code development and code review process.
• Provide weekly status updates to key stake-holders on development status.

Qualifications Required

BS/MS/BE/BTech or ME/MTech in EE, CS, or CE with 12 to 15 years of relevant firmware experience.
