Job Description

Firmware Engineer 5

Duties of Position

(Include specific duties and responsibilities)

The Person Should Perform The Following In His Role

• 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.
• Hardware Protocols: Advanced troubleshooting of I2C/I3C, SPI, eSPI, PCIe/VDM, and PMBus.
• Languages: Expert C/C++ (specifically modern C++ used in OpenBMC) and Python/Go for automation.
• Cloud-Scale Tooling: Experience with Git, Gerrit, Jenkins, and containerization (Docker) for firmware build environments.
• Hardware Bring-up: Experience with Aspeed AST2500/AST2600 (the industry-standard BMC chips) and low-level debugging using JTAG, oscilloscopes, and logic analyzers.
• BMC rebranding.
• Linux Socket programming and IPC, Shell scripting Knowledge in GPUs, Linux drivers development.
• Knowledge and development experience in Web scripting, test Automation scripts Software security, Knowledge in SATS.
• Process development & Documentation System debugging, Firmware testing (Unit, Acceptance) and Validation.
• Hyper scale Experience: Proven track record of shipping firmware for Hyper-scalar data centre products (AWS, Azure, Meta, or Tier 1 OEMs).
• Strong history of working with Open-BMC; experience replacing proprietary stacks (AMI, Avocent) with open-source alternatives is highly preferred.
• Comprehensive understanding of modern server topology, including CPUs (Intel/AMD), GPUs, and NVMe storage. Experience implementing Cerberus, Titan, or similar hardware security protocols. Ability to represent the company in industry forums (OCP) and collaborate with geographically distributed open-source contributors.

Qualifications Required
