System Validation Engineer

NewPhotonics is a fabless semiconductor engineering innovative optical-first silicon photonic product and technology for AI interconnect in data centers and hyperscaler infrastructure. Our market-disrupting PIC solutions enable energy efficiency, production simplicity and volume manufacturing of pluggable, NPO and CPO chips and engine platforms that will compact-packaged optical connectivity in scale-out, scale-up and scale-across networks. Job Description We are looking for a System Validation Engineer to take ownership of system-level validation for our next-generation silicon photonics ICs powering hyperscale data center transceivers. You will be involved with defining test strategies and automation architectures to hands-on silicon bring-up, working alongside Systems and Firmware engineering to directly shape the quality and maturity of our optical platforms. Main Responsibilities Execute rigorous system-level validation plans for advanced photonic ICs and high-speed optical links. Evaluate comprehensive PIC behavior across electrical, thermal, and optical domains, validating modulators, optical receivers, and integrated monitoring circuitry. Execute multi-corner PVT characterization to ensure robust operational margins under extreme environmental conditions. Investigate and root-cause hardware, optical, and firmware-level bottlenecks across the entire optical datapath. Collaborate closely with Firmware, Systems, Optical Engineering, and Algorithms groups to drive defect resolution and optimize overall transceiver performance. Qualifications & Requirements B.Sc. in Electrical Engineering, Computer Engineering, or a related discipline. 2+ years of hands-on experience in silicon- or system-level validation for high-speed ICs or optical transceivers. Demonstrated lab proficiency with high-speed test instrumentation (BERT, oscilloscopes, optical meters). Solid programming skills in Python for test bench automation, instrument interfacing, and data processing. Independent problem-solver with strong task-prioritization skills, comfortable operating in a fast-paced environment with minimal guidance. Star Candidate Advantages Direct experience characterizing coherent optical transceiver modules. Proven background in DSP or high-speed ASIC post-silicon bring-up and debug. End-to-end silicon bring-up experience, extending to customer platform integration and field issue triage. Prior experience thriving in dynamic, fast-paced startup cultures.
