BIOS Development Engineer

Mandatory Skills ● Experience in x86 BIOS/UEFI development. ● Strong understanding of x86 CPU/APU architectures and compilation tools. ● Expert-level C programming. ● Experience with at least one BIOS codebase: ○ AMI ○ Insyde ○ Phoenix BIOS ○ Coreboot ○ EDK II ● Experience preparing BIOS for platform bring-up. ● Understanding of UEFI boot stages: SEC, PEI, DXE, and BDS.

● Knowledge of PCDs, UPDs, memory maps, SPI ROM, FSP, device trees, and BIOS hand-off to the OS bootloader. ● Understanding of BIOS interaction with EC, BMC, security processors, power-management firmware, and memory-training firmware. ● Working knowledge of I2C, PCIe, SPI, eSPI, ACPI, SMM, IPMI, and UEFI. ● Experience with hardware-debugging tools such as AMD HDT, BIOS Debugger, ITP, or Arium.

● Experience with Coreboot and FSP source code. ● Experience with Coreboot payloads such as EDK II, SeaBIOS, U-Boot, LinuxBoot, and TianoCore. ● Experience with UEFI bootloaders or UEFI applications involving AHCI, SATA, or NVMe. ● Ability to read hardware and processor specifications for platform or mainboard porting.

● Exposure to pre-silicon BIOS development using simulation or emulation environments. ● Exposure to Synopsys ZeBu, Cadence Palladium, or Siemens Veloce.

Requirements

Additional Skills ● Git knowledge for code reviews, source-code management, and BIOS releases. ● Strong understanding of SATA, NVMe, AHCI, PCIe, SPI, eSPI, and IPMI. ● Strong understanding of ACPI, SMM, x86-64 architecture, and UEFI BIOS boot flow. ● Experience with Android UEFI-based bootloaders would be advantageous.

● Ability to manage multiple tasks and custom BIOS requirements.

Education

● Bachelor’s degree in Computer Science Engineering. ● A relevant master’s degree would be an advantage. ●
