Test Systems Design Engineer – Optical Subsystem IQC/OQC & Automation

This role focuses on developing IQC and OQC stations to screen incoming optical components and verify outgoing optical subsystem performance.

About the role

This role involves owning the design and development of optical test systems to ensure component and system quality throughout the manufacturing process for Lyte’s advanced technology. You will architect and build test solutions end to end, including opto-mechanical fixturing, instrumentation selection and integration, motion and machine-vision automation, and test software.

What you'll do

• Design and build automated IQC stations to screen incoming optical components: macro lenses, optical windows, and sub-assemblies.
• Design and build automated OQC stations to verify outgoing optical subsystem performance and fully assembled system modules.
• Architect the full test system: opto-mechanical fixturing, motion stages, precision instrumentation, machine vision, and robotic or conveyorized part handling.
• Develop station control and data-acquisition software (Python, LabVIEW, and/or C++) for instrument control, data logging, and MES interface.
• Translate optical and opto-mechanical design tolerances into measurable test coverage, acceptance criteria, and Cp/Cpk-capable test methods.
• Correlate subsystem-level optical results with system-level 4D FMCW lidar performance.

What you'll need

• M.S., or Ph.D. in Optical Engineering, Photonics, Electrical Engineering, Mechanical Engineering, Physics, or a related field—or equivalent practical experience.
• 5+ years designing automated test equipment or test fixtures for optical, optoelectronic, or opto-mechanical products.
• Hands-on experience with optical test instrumentation: MTF/resolution benches, interferometers, collimators, optical power meters or optical spectrum analyzers, and beam profilers.
• Proficiency in test automation programming (Python and/or LabVIEW; C++, C#, or MATLAB) for instrument control, data acquisition, and pass/fail decision logic, including integration of precision motion control.
• Working knowledge of lens and optical assembly specifications: MTF, distortion, focal length, back focal distance, chief ray angle—and opto-mechanical tolerancing.
• Demonstrated experience taking a tester from laboratory prototype into production at a vendor, CM, or OSAT site, including replicating multiple matched tools and proving tool-to-tool correlation.
• Willingness and ability to travel between the US and Asia manufacturing sites (up to ~25%).

Nice to have

• Direct experience testing lidar, camera, or laser transmitter/receiver optical engines; FMCW or coherent detection systems.
• Experience defining IQC/OQC processes with SPC, Cp/Cpk-based acceptance criteria, gauge R&R, and golden-unit and calibration traceability.
• Familiarity with MES integration, SECS/GEM, or shop-floor data collection systems.
• Machine vision and robotic or conveyorized part handling integrated into production test fixtures.
• Camera or lens IQC test benches—resolution/MTF charts, distortion mapping, stray light and ghost image characterization.
• Background in wafer-level or die-level optical/photonic test, chip-on-carrier (CoC) test, or burn-in test.
• Statistical and data analysis tools (JMP, Minitab, or Python) and CAD tools (SolidWorks) for fixture design.
• Prior working relationships with Taiwan-based contract manufacturing and OSAT partners.
