Senor Characterization and Test Engineer

Responsibilities:

• Lead electrical, optical, thermal, and mechanical characterization programs for photonic devices, packages, and assemblies, from test plan definition through execution and reporting.
• Own the design of test plans and DOEs supporting product development, process validation, reliability qualification, and failure analysis, and review/approve plans developed by junior team members.
• Drive selection, setup, and qualification of laboratory equipment, including optical measurement systems, vibrometers, thermal imaging systems, and mechanical testers, and define best practices for their use.
• Independently analyze and interpret complex test data, identify performance and reliability trends, and translate findings into engineering recommendations for product and packaging teams.
• Lead root-cause investigations and failure analysis efforts, coordinating across characterization, packaging, reliability, and manufacturing to close out issues.
• Develop and maintain automated test scripts, data pipelines, and analysis tools (Python or similar) to improve lab throughput and data quality.
• Author technical reports and present findings and recommendations to cross-functional and leadership audiences.
• Define and build new characterization methods, test fixtures, and lab capabilities to support next-generation photonic products.
• Own qualification and reliability test programs, including thermal, mechanical, and environmental stress testing, and represent characterization in design/qualification reviews.
• Establish and maintain lab documentation, test procedures, and equipment calibration standards; ensure compliance across the team.
• Mentor and provide technical guidance to junior characterization/test engineers and lab technicians.
• Partner with product, packaging, reliability, process, and manufacturing engineering to resolve complex technical challenges and influence design decisions.
• Experience/Qualifications:
• Bachelor's degree in Mechanical Engineering, Optical Engineering, Applied Physics, or a related discipline with 8+ years of relevant experience, or Master's degree with 5+ years of relevant experience, in engineering characterization, testing, laboratory operations, or product development.
• Demonstrated hands-on expertise operating and troubleshooting characterization equipment including Infrared Thermography, Laser Doppler Vibrometers (LDV), Instron Universal Mechanical Testers, and C-Mode Scanning Acoustic Microscopy (C-SAM).
• Track record of independently analyzing thermal, mechanical, vibration, and package integrity data to drive product development, reliability, and failure analysis decisions.
• Deep experience with laboratory instrumentation and data acquisition system design/integration.
• Solid working knowledge of optics, photonics, electronics, semiconductor devices, or advanced packaging technologies.
• Proficiency with data analysis tools such as Python, MATLAB, JMP, or equivalent, including building automated analysis pipelines.
• Strong command of Design of Experiments (DOE) and statistical analysis methods, with experience designing (not just executing) test programs.
• Demonstrated ability to lead technical investigations and communicate findings to cross-functional and senior stakeholders.
• Experience mentoring or informally leading junior engineers or technicians.
• Excellent written and verbal communication skills. Preferred Qualifications
• Direct experience with photonic devices, optoelectronics, semiconductor packaging, or advanced manufacturing.
• Experience with optical alignment, imaging systems, or optical characterization technique development.
• Experience building test automation frameworks or new test capability from scratch.
• Experience leading reliability testing or failure analysis programs, including ownership of qualification test plans.
• Experience presenting technical results in design reviews or to leadership.
