Lead BIOS Engineer – Switch Platform (Wireline)

About The Role We are seeking an experienced and self-driven BIOS Engineer to join our firmware and system software team. In this role, you will be responsible for designing, developing, and maintaining BIOS/UEFI firmware for 800G datacenter switch platforms, working closely with hardware, BMC, PRoT, and cross-functional engineering teams to deliver reliable, secure, and high-performance firmware solutions throughout the full platform lifecycle.

Key Responsibilities

• Design, develop, maintain, and debug BIOS/UEFI firmware based on switch hardware architecture and platform design requirements.
• Perform high-level and low-level design, implementation, and integration of new BIOS features including power sequencing, hardware initialization, PCI enumeration, and boot flow management.
• Lead or contribute as a platform owner or domain expert, providing technical guidance and mentoring to team members on BIOS architecture and bring-up.
• Collaborate with hardware, BMC, PRoT, and SONiC/NOS teams to bring up and validate BIOS on custom switch platforms, ensuring correct handoff between firmware layers.
• Implement and maintain secure boot, measured boot, and UEFI Secure Boot configurations aligned with platform security policy.
• Develop and maintain platform ACPI tables, SMBIOS structures, and UEFI device drivers for switch-specific hardware components.
• Participate in system integration, validation, and issue root-cause analysis across the full switch platform development cycle.

Required Qualifications

• Hands-on experience with BIOS/UEFI firmware development using EDK2 or proprietary UEFI frameworks.
• Strong C/C++ programming skills, with solid understanding of embedded firmware architecture, code tracing, and low-level debugging.
• Good understanding of x86 or ARM processor initialization, memory controller bring-up, and platform boot flows.
• Solid knowledge of low-level hardware protocols commonly used in BIOS bring-up: PCIe, SPI (flash), I2C, SMBus, UART, GPIO, eSPI.
• Strong understanding of UEFI specifications including UEFI PI, SMM, DXE, PEI, BDS, and shell environments.
• Familiarity with ACPI specification, ASL programming, and SMBIOS table construction for platform hardware description.
• Ability to independently port BIOS firmware to custom hardware platforms or implement platform-specific initialization sequences.
• Experience participating in at least one complete hardware platform lifecycle (from bring-up to production).
• Bachelor's or Master's degree in Electronics, Computer Engineering, Software Engineering, or a related field.

Preferred Qualifications

• Experience with datacenter switch or networking hardware platforms (e.g., 400G/800G switch ASICs, OCP-compliant designs).
• Familiarity with secure boot integration, TPM 2.0, measured boot, and PRoT/RoT attestation flows from the BIOS layer.
• Experience acting as a technical lead, platform owner, or domain expert in BIOS-related projects.
• Familiarity with OpenBMC or IPMI/Redfish interactions from a BIOS/BMC interface perspective (e.g., BIOS-BMC communication via IPMB, SSIF, or BT).
• Experience with hardware bring-up, manufacturing diagnostics, or platform validation tooling.
