Top Tech Jobs & Startup Jobs

Develop and optimize wet etch processes for GaAs and InP optoelectronic devices (VCSELs, photodiodes, EMLs). Control etch chemistry, rates, selectivity, and surface quality; use metrology (SEM, AFM, XPS, XRD, ellipsometry) for characterization; troubleshoot yield and material issues; establish SPC/DOE, qualify chemistries/equipment, document SOPs, and mentor junior engineers while integrating processes into fabs.

The role involves designing silicon photonic integrated circuits, validating designs, supporting tapeouts, and collaborating with cross-functional teams for product development.

The role involves engineering support for photonic manufacturing, focusing on cost reduction, yield improvement, and quality assurance. Responsibilities include process development, data analysis, problem-solving, and training production staff.

Lead design and development of fiber optic transceivers and optical engines through concept to production. Perform co-design of PICs, ICs, substrates, connectors and packaging; run analysis, modeling, simulation and lab measurements; create drawings/BOMs/ECOs; resolve DFM issues; and coordinate cross-functional teams through EVT/DVT reviews.

Lead complex, multi-year cross-business programs: establish governance, align stakeholders, manage risks, report metrics to executives, drive continuous improvement and change management to realize strategic objectives.

Lead optical transceiver design and validation: run link and RF simulations, perform electrical and optical measurements, create firmware requirements and compliance reports, and present results internally and to partners.

The Principal Engineer leads software development for optical networking products, mentors junior engineers, and supports pre and post-sales interactions. Requires expertise in embedded systems, C/C++, and networking protocols.

Lead mechanical design and integration for test, assembly, and characterization equipment for high-power lasers and co-packaged optics. Collaborate with R&D, manufacturing, product engineering, and cross-functional teams to optimize production, ensure quality, and meet schedules. Oversee automated test systems, motion and vision systems, thermal management, and instrumentation for both R&D and mass production.

Design and implement embedded real-time control firmware for microcontroller and FPGA-based products. Develop control algorithms, perform unit and robustness tests, maintain firmware documentation, support NPI/manufacturing/customers, debug hardware with lab tools, mentor junior engineers, and improve CI/CD and development practices.

Lead system verification for optical networking products: define test strategy, design test plans, automate Python-based regression and CI/CD pipelines, validate northbound interfaces (Netconf/gRPC/CLI/SNMP/REST) and DWDM/OTN features, run regression and sanity tests, produce release reports, and mentor junior verification engineers while collaborating with HW/SW and architecture teams.
