About the role
We're hiring a senior firmware engineer to architect, develop, and bring up embedded firmware for Ethernet SerDes, retimers, and diagnostics. The role covers SerDes, calibration, manufacturing, and test firmware. You'll work closely with ASIC, module, manufacturing, test, and reliability teams. You'll define ARM and RISC-V control architectures, write digital requirements for custom control ASICs, build a solid firmware development and CI flow, and mentor engineers across programs.
What they're looking for
- Architecture & Development: Architect, develop, debug, and release production firmware for next-generation optical engines and module platforms (SFP/QSFP/OSFP)
- ASIC & System Specification: Define digital requirements for custom control ASICs, including MCU selection, memory maps, boot sequence, peripherals, telemetry, diagnostics, MACsec engines, and PTP hardware timestamping
- System Integration: Partner with ASIC, RTL, and verification teams on architecture, board bring-up, and system-level debug
- Protocols & Interfaces: Build and maintain firmware for Ethernet, PCIe, and SerDes (link training, interop, compliance), PTP/IEEE 1588, MACsec, and host interfaces
- Bring-Up & Diagnostics: Lead first firmware bring-up on new modules and ASICs, and drive root-cause analysis across lab, qualification, and field returns
- Manufacturing & Calibration: Deliver firmware for manufacturing test, screening, calibration engines, and lookup tables that support high-yield production
