Photonic Integrated Circuit Researcher

Location: Santa Clara, California

Work Arrangement: Onsite

Employment Type: Full-Time

Required Education: Completed Ph.D. in a relevant field

Experience: Research experience in integrated photonics; candidate details list 2–5 years The ideal candidate is a Ph.D.-qualified photonics researcher with strong theoretical knowledge and practical experience designing, simulating, laying out, and characterizing photonic integrated circuits. A strong candidate should be able to connect optical waveguide theory with real-world device performance, perform hands-on laboratory measurements, interpret experimental results, and translate research concepts into practical hardware and software demonstrations. Candidates with experience in PIC foundry tape-outs, circuit-level simulation, RF or microwave design, packaging, or Python-based lab automation will have additional strengths. The Photonic Integrated Circuit (PIC) Researcher will invent, develop, simulate, design, and validate advanced integrated photonic technologies at Keysight Laboratories. This role combines measurement science, optical waveguide theory, PIC design, simulation, layout, and hands-on component characterization. The researcher will investigate emerging technologies, develop innovative measurement concepts, implement solutions in hardware and software, and demonstrate technical feasibility. Successful innovations may be transferred to Keysight business units for integration into commercial products. The position requires a strong theoretical and practical understanding of integrated photonics, a research-oriented mindset, and the ability to collaborate with multidisciplinary engineering teams. This role isonsite in Santa Clara, California, and relocation assistance may be available for an ideal candidate.
