Job description

Senior Analog & Mixed-Signal Design Engineer – Optical Interconnects

San Jose, CA | $150,000–$300,000 + Bonus

A growing semiconductor company is developing next-generation high-speed connectivity for AI datacentres, cloud infrastructure and high-performance computing.

They're looking for an experienced Analog/Mixed-Signal Design Engineer with exposure to silicon photonics and electro-optic systems to develop advanced electrical and optical transceivers operating at 100G per lane and beyond.

The Role

• Develop architectures for high-speed SerDes and optical transceivers, including EIC/PIC integration and link-budget definition.
• Design and verify high-performance analog and mixed-signal circuits, including modulator drivers, TIAs, ADCs/DACs, PLLs, CDRs and clocking circuits.
• Model electro-optic systems and photonic components using MATLAB, Python or Verilog-A.
• Collaborate with photonics, DSP, packaging and signal integrity teams to optimise performance and integration.
• Support silicon bring-up, lab testing, debugging and post-silicon validation through to production.

What We're Looking For

• MS or PhD in Electrical Engineering, Applied Physics or a related field.
• Strong high-speed analog CMOS design experience in advanced process nodes.
• Experience with SerDes, wireline transceivers or optical transceiver design.
• Familiarity with silicon photonics and electro-optic devices, such as MZMs, MRMs, EAMs and photodetectors.
• Proficiency with Cadence, mixed-signal simulation and MATLAB or Python.

Experience with 100G/lane PAM4, Verilog-A photonic modelling, Lumerical, silicon photonics PDKs or co-packaged optics (CPO) is highly desirable.

• $150,000–$300,000 base salary, depending on experience.
• Performance bonus and potential short- and long-term incentives.
• Comprehensive healthcare, 401(k), paid leave and additional benefits.
