BIOS Firmware Engineer

Location: Austin - Onsite preferred, hybrid/100% remote can be considered for the right candidate Top skills: o UEFI background o C programming o BIOS/pre-OS silicon initialization o EDKII THE ROLE: Our client is looking for a software/firmware developer to join the team and help develop pre-OS BIOS firmware and silicon initialization code. As part of the role, the BIOS engineer will work closely with other firmware developers and architects in designing and implementing X86 and/or RISC-V firmware that spans pre- and post-silicon for all client business units. THE PERSON: Passionate about firmware development on bare-metal or close to bare-metal environment. Need strong problem-solving skills, with a collaborative can-do attitude. Strong knowledge of computer architecture and low-level programming in C KEY RESPONSIBILITIES: Developing, porting, debugging, and documenting core firmware support for configuration and enablement of various features, including PCI Express and related functionality, DRAM technologies (DDR4, DDR5), internal graphics, IO virtualization, SOC power management, etc., on AMD Desktop, Mobile, and Enterprise SoCs Supporting emulation/simulation teams during pre-silicon phase to validate SOC hardware and firmware components. Working closely with hardware validation teams to verify and optimize performance of IP subsystems. Developing custom firmware features for internal and external customers. Engage with technical leads to understand firmware scope and work on implementation to meet schedules and milestones. Work with internal and external teams to ensure highest level of quality and satisfaction throughout firmware lifecycle. Must be well-organized, technically oriented, and a self-starter with a demonstrated ability to work collaboratively and coordinate activities with geographically distributed technical teams. Desire to work and succeed on fast-paced and highly dynamic environments QUALIFICATIONS: Bachelor s (required) or Master s degree (preferred) in Computer Science, Computer Engineering, Electrical Engineering, or equivalent with at least 5-10 years of experience PREFERRED EXPERIENCE: Development and support of multi-root PCI Express subsystems for Enterprise systems, including extensions such as Universal Backplane Management, Compute Express Link, hot-plug, etc. Strong background in computer architecture with familiarity in memory interleaving, system memory maps and NUMA domain concepts In-depth UEFI BIOS development experience with familiarity on at least one BIOS code base (AMI, Insyde or Phoenix BIOS) Familiarity with memory industry standards and technologies such as JEDEC, SPD Data, I2C/I3C, DDR4/5, LPDDR4/4x/5/5x UDIMM, RDIMM, LRDIMM, 3DS, ECC, Mode Registers, Self-Refresh, etc. Good understanding of firmware development cycle, integration, and verification/validation for pre-si and post-si for SoC designs. Expertise in low-level C programming & debugging for embedded systems. Ability to methodically root-cause complex failure mechanisms at the IP, subsystem and/or system level. Prior experience and/or exposure to testing platforms (Simulation and/or Emulation) Prior involvement in board, processor, or ASIC bring-up. Experience in hardware/software interfaces and debugging sophisticated issues in CPU and firmware using JTAG, source code debuggers and other tools. Experience with source control systems including git/github Excellent written and verbal communication and presentation skills.
