Photonics Validation Engineer – High‑Volume PIC Testing

About the role

Mesh Optical Technologies is building large‑scale photonic integrated circuits for next‑generation optical systems. The Photonics Validation Engineer will own the end‑to‑end validation lifecycle, from wafer‑level test development to module‑level quality screening, ensuring high‑volume production meets strict performance and yield targets.

Key responsibilities

• Define test processes and coverage for PICs across wafer, die, and integrated module levels in collaboration with design, electrical, mechanical and test teams.
• Lead risk identification and mitigation for PIC and laser testing, and contribute to optical component development for future products.
• Measure and characterize optical and electrical building blocks of PICs.
• Develop and automate lab validation, quality screening and manufacturing metrology solutions.
• Specify and build test fixtures and software together with optical, electrical, mechanical and firmware groups.
• Work with internal engineering groups and external suppliers to pinpoint performance, yield, reliability and quality drivers.
• Provide technical feedback and test requirements to suppliers to enable reliable production processes.

Required profile

• Bachelor’s or Master’s degree in electrical, computer or optical engineering (or related field); PhD is a plus.
• 5+ years of hands‑on experience in validation and high‑volume testing of photonic integrated circuits.
• Proven background with silicon photonics, optical interconnects and manufacturing workflows.
• Experience with electro‑optic wafer‑ and die‑level test systems and optical/RF test equipment.
• Programming experience (C++, LabVIEW, Python) and willingness to work extended hours as needed.

Required skills

• C++
• LabVIEW
• Python (including PyVISA, MATLAB)
• Spectrum analyzer
• Vector network analyzer (VNA)
• Voltage signal generator (VSG)
• High‑speed oscilloscope
• Bit‑error‑rate tester (BERT)
• Electro‑optic wafer‑level test systems
• Die‑level test systems
• DSP concepts (FFE, DFE, CTLE)
• Optical communications metrics (OSNR, receiver sensitivity, OMA, optical filtering)
