Firmware Engineer - Optical Transceivers

Location: San Jose, CA (Primarily onsite, with reasonable flexibility)

Employment Type: Full-Time, Permanent

Industry: Telecommunications

Report to: The head of the local U.S. R&D and FAE team. The team currently has around 7-8 members and is continuing to expand.

Experience Level: 2-3 years in optical transceiver firmware development

Note: Must have legal authorization to work in the United States. No Corp-to-Corp (C2C/C2H) or Visa sponsorship provided.

Position Overview:

We are seeking a motivated Firmware Engineer to join our optical transceiver development team. The ideal candidate will have 2-3 years of hands-on experience in embedded firmware design for optical or high-speed communication modules. You will collaborate closely with our hardware, optics, and test teams to implement and optimize control algorithms, monitoring functions, and communication protocols for our optical transceivers.

Key Responsibilities:

• Develop, test, and maintain embedded firmware for optical transceiver modules (10G-1.6T).
• Implement control and monitoring logic for lasers, TECs, and photodiodes.
• Integrate and debug low-level drivers (I2C, SPI, MDIO, etc.) and state machines.
• Support implementation of industry standards such as CMIS, SFF, and IEEE specifications.
