The AWS BIOS Engineering team creates and maintains custom firmware solutions for Amazon's innovative server platforms. Our BIOS/UEFI implementations are industry-leading in security, performance, and operational excellence, and are critical to the success of AWS's massive-scale infrastructure that millions of customers rely on daily. Our BIOS engineers solve complex firmware challenges and build robust, secure bootloader solutions that enable AWS to maintain its competitive edge in cloud computing. The ideal candidate will be an innovative self-starter with deep expertise in UEFI/BIOS development. You will be a firmware specialist with comprehensive knowledge of x86 and ARM64 architecture, secure boot implementations, and low-level system programming. You will gain intimate understanding of AWS's custom server firmware stack and analyze it for both current needs and future scalability. You will leverage your system-level expertise to find optimal solutions to complex boot-time challenges. You will collaborate with internal teams (hardware, validation, security) and external partners (silicon vendors, ODMs) while leading critical firmware development efforts. What you will do: - Design and implement custom UEFI/BIOS features for AWS server platforms - Debug complex firmware issues using tools like ITP, ScanTool, and JTAG - Optimize boot time performance and platform initialization sequences - Implement secure boot mechanisms and firmware security features - Develop and maintain Power-On Self Test (POST) code - Create firmware update mechanisms and recovery solutions - Work with hardware teams on board bring-up and platform validation Why it matters: AWS's custom server platforms require specialized firmware solutions that maximize performance, security, and reliability at scale. Your BIOS developments will directly impact millions of servers running in AWS data centers worldwide, requiring unique optimizations that benefit our cloud infrastructure and customers. Why
