ARM Platform Firmware Development/ Embedded Firware Developer

Role & responsibilities

Design, develop, port, and integrate U-Boot bootloader features for Arm and AArch64-based platforms

• Develop and integrate TF-A components, including BL1, BL2, BL31, platform ports, secure monitor functionality, and the handoff to normal-world software
• Develop, customize, and debug SCP firmware for system control, power management, clock management, reset control, sensors, and platform management functions
• Enable new SoCs, boards, and reference platforms from early silicon and board bring-up through production release
• Implement platform initialization flows covering CPU, memory, storage, PCIe, USB, Ethernet, interrupt controllers, timers, and peripheral interfaces
• Configure and maintain device trees, boot scripts, boot commands, environment handling, image loading, and Linux boot flows
• Integrate secure boot, chain-of-trust, firmware authentication, measured boot, trusted execution, and platform security features
• Implement and debug interactions among U-Boot, TF-A, SCP firmware, Linux, trusted operating environments, and platform hardware
• Perform low-level firmware debugging using JTAG, trace tools, UART, logic analyzers, oscilloscopes, and platform-specific debug utilities
• Analyze hardware schematics, register specifications, memory maps, boot logs, and crash dumps to diagnose system-level issues
• Collaborate with silicon vendors, platform architects, hardware teams, Linux teams, validation teams, and customers to define and implement platform requirements
• Drive firmware quality through design reviews, code reviews, unit and integration testing, static analysis, performance optimization, and defect prevention
• Support firmware build systems, cross-compilation toolchains, source-control workflows, continuous integration, and release processes
• Document firmware architecture, boot flows, interfaces, design decisions, debug methods, and customer solutions
• Mentor engineers and contribute to technical planning and resolution of complex platform firmware challenges

Preferred candidate profile

Experience with the Firmware Framework for Arm A-profile (FF-A), Secure Partition Manager, Trusted Board Boot, and firmware update mechanisms

• Experience with OP-TEE, Trusted Execution Environments, secure boot, measured boot, TPM, or hardware roots of trust
• Familiarity with SCMI, PSCI, SMC calling conventions, power-domain management, and communication between application processors and system-control processors
• Experience with EDK II or UEFI on Arm platforms as an additional qualification
• Experience enabling server, AI, edge-computing, embedded, networking, or IoT platforms
• Knowledge of Yocto Project, Buildroot, Linux kernel development, or board support packages
• Experience with upstream open-source development, patch submission, code review, and community collaboration
• Experience working directly with OEMs, ODMs, silicon vendors, or hyperscale customers
