BIOS Engineer – Switch Platform (Wireline)

Job Title

BIOS Engineer – Switch Platform (Wireline)

Role Summary

Design, develop, and maintain BIOS/UEFI firmware for 800G datacenter switch platforms. Work with hardware, BMC, PRoT, and NOS teams to deliver reliable, secure, high-performance firmware across the platform lifecycle.

Experience Level

Mid-level. The role expects prior BIOS/platform bring-up experience and participation in at least one complete hardware platform lifecycle; no explicit years of experience are stated.

Responsibilities

Key responsibilities include firmware design, platform bring-up, and cross-team validation.

• Design, develop, maintain, and debug BIOS/UEFI firmware based on switch hardware and platform requirements.
• Perform high-level and low-level design and implementation of features such as power sequencing, hardware initialization, PCI enumeration, and boot flow management.
• Act as platform owner or domain expert; provide technical guidance and mentoring to engineering team members.
• Collaborate with hardware, BMC, PRoT, and SONiC/NOS teams to bring up and validate BIOS on custom switch platforms and ensure correct firmware layer handoffs.
• 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, root-cause analysis, and release activities across the full platform development cycle.
• Support porting BIOS firmware to custom hardware platforms and perform low-level debugging and validation.

Requirements

Must-have technical skills and experience.

• Hands-on BIOS/UEFI firmware development experience using EDK2 or proprietary UEFI frameworks.
• Strong C/C++ skills and experience with embedded firmware architecture, code tracing, and low-level debugging.
• Understanding of x86 or ARM processor initialization, memory controller bring-up, and platform boot flows.
• Working knowledge of low-level hardware protocols: PCIe, SPI (flash), I2C, SMBus, UART, GPIO, eSPI.
• Familiarity with UEFI specifications (UEFI PI, SMM, DXE, PEI, BDS) and UEFI shell environments.
• Experience creating ACPI tables, ASL, and SMBIOS structures for platform hardware description.
• Proven ability to port BIOS firmware to custom hardware and support platform bring-up activities.
• Experience participating in at least one complete hardware platform lifecycle (bring-up through production).

Nice-to-have:

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

Education Requirements

Bachelor's or Master's degree in Electronics, Computer Engineering, Software Engineering, or a related technical field.
