  • Experience as a mentor, tech lead, or leading an engineering team
  • 6+ years of bare-metal firmware or BIOS/UEFI development experience in C (not embedded Linux or kernel driver development)
  • 6+ years of bare-metal firmware development experience in C on MCUs, SoCs, or server platforms

Qualifications

  • Bachelor's degree in computer science or equivalent
  • BIOS/UEFI/EDK2/Coreboot development experience on x86 or ARM server platforms
