Mesh Optical Technologies was founded on the belief that optical photons will be at the center of advanced technologies in the coming century. Making advanced technology ubiquitous means building at scale, and that’s exactly what we’re doing at Mesh. High-volume photonics manufacturing requires validation strategies that catch issues early and hold the line on quality as production ramps. We are seeking a Photonics Validation Engineer to define and lead test processes for our photonic integrated circuits across wafer, die, and module levels. You will own the validation lifecycle—developing automated test solutions, identifying performance and yield drivers, and partnering with design and supplier teams to ensure every component that ships meets the standards our technology demands. RESPONSIBILITIES:
Work with PIC design, electrical, mechanical, and test teams to define test processes and coverage for Photonic Integrated Circuits (PICs) across wafer, die, and integrated module test levels
Lead identification and mitigation of test risks specifically for PICs and lasers
Contribute to optical components development and validation for next generation products
Measure and characterize PIC optical and electrical building blocks
Develop and automate test solutions for lab validation, quality screening, and manufacturing metrology
Specify and develop test fixtures in collaboration with optical, electrical, and mechanical teams
Specify and develop test software in collaboration with optical, electrical, test software, and firmware teams
Work with internal engineering teams and suppliers to identify drivers of performance, yield, reliability, and quality issues
Interface with suppliers to provide technical feedback and test requirements to develop reliable processes
QUALIFICATIONS:
Bachelor’s or Master’s in electrical engineering, computer engineering, optical engineering, or a related discipline
5+ years of hands-on industry experience in validation and high-volume test of PIC products
Proven experience with optical interconnects and silicon photonics test and manufacturing workflows
Hands-on experience with electro-optic wafer- and die-level test systems
Hands-on familiarity with optical/RF test equipment (e.g., spectrum analyzers, VNAs, VSGs, high-speed oscilloscopes, BERTs)
1+ years of programming experience (e.g., C++, LabVIEW, and/or Python)
Willingness to work extended hours and weekends as needed
PREFERRED EXPERIENCE:
PhD in electrical engineering, computer engineering, optical engineering, or a related discipline
Test automation software development experience (e.g., Python/PyVISA, MATLAB, or similar)
Familiarity with DSP concepts (e.g., FFE, DFE, CTLE) and optical communications metrics (e.g., OSNR, receiver sensitivity, OMA, optical filtering)
Experience defining supplier test requirements and driving supplier execution for production ramps
Experience writing test plans and procedures, and delivering go/no-go decisions with clear rationale
