Optical Test Engineer

OPTICAL TEST ENGINEER

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.

Scaling advanced photonics demands test and measurement systems as sophisticated as the devices themselves. We are seeking an Optical Test Engineer to design, build, and validate the optical test infrastructure that ensures our products meet rigorous performance, yield, and reliability standards-from wafer-level characterization through integrated module validation. You will be the critical link between design intent and production reality, turning data into actionable insight across every stage of our manufacturing pipeline.

RESPONSIBILITIES:

• Partner with PIC design, electrical, mechanical and test teams to define requirements for production and develop test approaches for complex hardware
• Design, build, and validate optical test systems including imaging, microscopy, polarimetry, profilometry, and interferometry
• Compile and analyze data sets to identify trends in performance
• Assist with validation activities, including performance characterization at the wafer-, die-, and integrated module level
• Work with internal engineering teams and suppliers to identify drivers of performance, yield, reliability, and quality issues
• Review designs for manufacturability; drive integration build flow, test operations, and execution readiness

QUALIFICATIONS:

• Bachelor's degree in electrical engineering, optical engineering, applied physics or an engineering discipline
• 2+ years of hands-on experience in optics, photonics, lasers, or test
• Working knowledge of lasers, photodiodes, fiber optics, optical test/troubleshooting methods, and signal integrity fundamentals
• Hands-on experience with optical test equipment (e.g., power meters, interferometers, spectrum analyzers)
• 1+ years of programming experience (e.g., C++, LabVIEW, and/or Python)
• Willingness to work extended hours and weekends as needed

PREFERRED EXPERIENCE:

• Master's degree or PhD in electrical engineering, optical engineering, applied physics or an engineering discipline
• Experience in optical lab or production environments with strong attention to detail
• Proficiency with optical design/analysis tools (e.g., Zemax)
• Experience integrating and testing electrical and/or avionics systems
• Experience with documentation practices and configuration management
• 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)
• Experience writing test plans and procedures, and delivering go/no-go decisions with clear rationale
• CAD proficiency (NX preferred)

COMPENSATION AND BENEFITS:

Pay range:
Optical Test Engineer: $120,000.00 - $160,000.00/per year

Title and base salary are determined on a case by case basis commensurate with experience and merit.

In addition to base salary, compensation for this role includes:

• Eligibility for long-term incentives including company stock options and discretionary bonuses awarded for exceptional achievements.
• Comprehensive medical, vision, and dental insurance with significant cost covered by the company for yourself and dependents.
• Paid parental leave and flexible PTO (3 weeks accrued vacation and 10 company holidays per year).
• 401(k) retirement plan access.
• Relocation assistance to sunny Los Angeles.
