Responsibilities and Duties 

• Define and lead validation strategy for rack-level firmware stacks across ARM-based server platforms. 

• Develop comprehensive validation plans and automated test frameworks for platform bring-up and firmware lifecycle. 

• Validate platform management interfaces including Redfish, PLDM, MCTP, IPMI, and D-Bus. 

• Validate firmware update frameworks including signed updates, redundancy mechanisms, and rollback protection. 

• Drive validation of platform security features including Root of Trust, secure boot chains, and TPM integration. 

• Validate server RAS capabilities, telemetry pipelines, and system health monitoring. 

• Lead system-level debugging and root cause analysis across firmware and hardware layers. 

• Develop automation frameworks and CI/CD integration for firmware validation and regression testing. 

• Validate high-speed platform interfaces including PCIe and server I/O subsystems. 

• Collaborate with silicon vendors, ODM partners, and engineering teams during bring-up and production ramp. 

Candidate Profile 

Essential 

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Computer Science, or equivalent experience. 

• 10+ years of experience in firmware or platform validation for server or data center systems. 

• Experience validating ARM server firmware stacks including UEFI/EDK II and OpenBMC platforms. 

• Deep understanding of server architecture including power delivery, thermals, networking, and rack infrastructure. 

• Strong experience validating platform management protocols such as Redfish, PLDM, MCTP, and IPMI. 

• Experience validating firmware security features including Root of Trust and secure boot. 

• Strong familiarity with firmware lifecycle management and update frameworks. 

• Experience with server hardware interfaces including I2C, I3C, SPI, PCIe, SMBus, UART, and GPIO. 

• Strong system debugging skills using JTAG, GDB, logic analyzers, and protocol analyzers. 

Desirable 

• Experience validating rack-scale firmware platforms in hyperscale or AI cloud environments. 

• Hands-on experience with EDK II/UEFI validation and OpenBMC system testing. 

• Experience validating firmware for liquid-cooled or high-density server platforms. 

• Experience building hardware-in-the-loop (HIL) or rack-level automated validation environments. 

• Experience validating high-speed interconnects such as PCIe in large-scale deployments.
