About the role
We are seeking an experienced firmware leader to architect, develop, and bring up embedded firmware for advanced Ethernet SERDES, Retimers and diagnostics. This role spans SERDES, calibration, manufacturing and test firmware, and close collaboration with SFP modules, ASIC, manufacturing, test, calibration, and reliability teams. The ideal candidate brings deep experience in firmware, defines ARM and RISC-V-based control architectures, generates digital requirements for custom control ASICs, drives robust firmware development flow and CI, and mentors engineers across programs.

What you'll do
• Architecture & Development: Architect, develop, debug, and release production-grade embedded firmware for next-generation optical engines and optical module platforms (SFP/QSFP/OSFP).
• ASIC & System Specification: Define digital requirements, MCU/processor choices, memory maps, boot sequence, and peripheral requirements for custom optical control ASICs—including control, telemetry, monitoring, interfaces, diagnostics, MACsec security engines, and PTP hardware timestamping.




• Cross-Functional System Integration: Partner closely with ASIC, RTL, and verification teams to drive end-to-end architecture definition, implementation alignment, board-level bring-up, and system-level debug.
• Protocol & High-Speed Interfaces: Implement and maintain firmware for high-speed protocols (Ethernet, PCIe, SerDes, link training, interoperability, and compliance), time-synchronization stacks (PTP/IEEE 1588), link encryption (MACsec), and host-facing interfaces.
• Platform Bring-Up & Diagnostics: Lead initial firmware and digital bring-up for current optical modules, engines, and control ASICs; execute root-cause failure analysis across lab bring-up, qualification, and field-return scenarios.
• Manufacturing & Calibration Engines: Design and deploy firmware for manufacturing test, screening, calibration engines, and lookup tables to enable high-yield volume production.
• DevOps & CI/CD
