Analog/Mixed-Signal IC Design Engineer

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. #J-18808-Ljbffr Langham Recruitment
