About the role
•
We are seeking a motivated and hands-on Optical System Integration Engineer to join our System Optics Team. The team is responsible for integrating and validating optical subsystems and ensuring product performance from an optical standpoint. This is a hands-on engineering role intended for a recent graduate, or early-career engineer with strong fundamentals in optics and an interest in building, testing, and debugging real optical systems.
What you’ll do
•
Build, align, and characterize optical laboratory setups and optical subsystems.
•
Support testing and validation of optical components and subsystems, including lenses, windows, mirrors, lasers, detectors, and related opto-mechanical assemblies.
•
Perform optical alignment tasks including free-space alignment, beam collimation, focusing, and optimization of optical paths.
•
Execute optical characterization and system-level test procedures and analyze the resulting data.
•
Develop Python scripts for instrument control, test automation, data processing, visualization, and analysis.
•
Assist with development and validation new sensor prototyping and manufacturing processes.
•
Support optical subsystem bring-up, integration, validation, and troubleshooting.
•
Investigate unexpected system behavior using experimental data and fundamental engineering principles.
•
Perform measurements and characterization of optical performance, including beam profile, M², wavefront error (WFE), and other relevant optical metrics.
•
Work with cross-functional engineering teams, including electrical, firmware, DSP, software, and mechanical engineering.
•
Document experimental setups, procedures, results, and conclusions clearly.
•
Participate in failure analysis and root-cause investigations with experienced engineers.
•
Propose improvements to optical setups, test methods, automation, and measurement techniques.
