Job Overview:
We are looking for a Principal UEFI Firmware Design Engineer to lead and drive the development of UEFI firmware across server and rack-scale platforms, primarily targeted for hyperscale data center environments. This role requires deep expertise in UEFI as applied to Servers based on ARM architecture, strong experience with CI/CD development workflows, and a proven track record of collaborating with ODM design partners to deliver high-quality, scalable firmware solutions. You will play a critical role in shaping the architecture, roadmap, and execution of next-generation platform management firmware.
Responsibilities:

• Lead the architecture, design, development, and deployment of UEFI-based firmware for hyperscale server and rack management platforms.
• Define and drive BMC feature development to meet hyperscaler requirements for reliability, scale, serviceability, and automation.
• Collaborate closely with ODM partners through all phases of the design and development lifecycle - from concept to mass production - ensuring timely and high-quality firmware deliverables.
• Guide and support integration of UEFI firmware into CI/CD pipelines, including automated builds, regression testing, static analysis, and deployment workflows.
• Design and implement robust and scalable firmware interfaces for platform initialization (CPU, Memory, PCIe and interconnects), system firmware security (RoT, Chain-of-trust, Signed FW updates, Secure Boot, etc.), Server RAS, and firmware update infrastructure.
• Partner with hardware, BMC, security, systems, and validation teams to drive alignment across the entire platform stack.
• Lead debug efforts on complex hardware/firmware/system issues in lab and production environments.
• Contribute to the UEFI/EDKII upstream community and drive adoption of industry standards relevant to hyperscale firmware management.
• Prior experience in UEFI development for ARM Servers is a MUST. Prior development experience in EDK II codebase is a MUST. Prior development experience is AMI Aptio codebase is desired.

Required Skills and Experience :

• Bachelor's or Master's degree or equivalent experience in Electrical Engineering, Computer Engineering, Computer Science, or a related field.
• 10+ years of hands-on experience in UEFI firmware development, with at least 3 years in a senior or lead engineering role.
• Strong expertise with UEFI, Tiano and related firmware code structures, and system firmware / software design.
• Experience leading UEFI firmware solutions in hyperscale environments (e.g., cloud service providers, large-scale data center infrastructure).
• Proficiency in C/C++, Linux / Windows kernel and userspace development, and scripting languages (Python, Bash).
• Deep knowledge of cache coherency protocols, DDR memory training concepts, PCIe sub-system for storage, networking, graphics controllers and accelerators.
• Solid understanding of server and rack-level hardware architecture (e.g., power delivery, thermal control, FRUs, sensors).
• Knowledge of BIOS-BMC interactions for the purposes of platform initialization, platform RAS, telemetry, firmware updates etc.
• Proven experience building and maintaining CI/CD pipelines (e.g., Jenkins, GitLab CI, GitHub Actions) for firmware development and validation.
• Experience with code static analysis tools and vulnerability scanners.
• Experience with system-level debug tools such as logic analyzers, JTAG, GDB.
• Extensive experience working with and leading ODM/JDM partners, including technical leadership, reviews, and issue triage.

"Nice To Have" Skills and Experience :

• Prior contributions to the UEFI/EDK II open-source community.
• Familiarity with firmware security technologies (secure boot, measured boot, signed images, TPM integration).
• Exposure to server platform architecture (x86/ARM), PCIe, BMC SoCs, and associated peripherals.
• Experience with DevOps or cloud-native workflows is a plus.

In Return:

• Be part of a groundbreaking team influencing the next generation of data center systems!
• Collaborate with premier engineers and vendors to develop industry-leading AI hardware.
• Access professional growth through sophisticated project involvement and multidisciplinary teamwork.
• Join a company committed to diversity and inclusion, where your work matters and drives global progress!
