We are currently looking for a Test Engineer to join our team onsite in our Orlando, FL office. We offer a 9/80 work schedule and foster a professional, high-energy culture where employees are empowered to succeed.

The Test Engineer is responsible for defining, developing, and validating test requirements, methods, and acceptance criteria for optical and electro-optical products across the product lifecycle, from engineering development through early manufacturing. This role ensures that test intent is technically sound, traceable to requirements, and scalable for manufacturing, serving as a critical interface between design engineering, manufacturing, and quality.

Responsibilities:

• Derive measurable test requirements from material specifications, drawings, standards, and customer requirements.
• Define test objectives, acceptance criteria, tolerances, guard bands, and uncertainty considerations.
• Develop engineering test specifications and procedures supporting EV, DV, PV, and sustaining phases.
• Design and implement automated test methods using LabVIEW, Python, C#, PLC-based systems, or commercial frameworks.
• Support procurement, commissioning, FAT/SAT, qualification, and sustainment of test equipment.
• Participate in Design for Testability (DFT) reviews and provide early technical feedback.
• Define required test data and ensure structured, traceable storage of results.
• Support root-cause investigations, yield analysis, and continuous improvement initiatives.
• Collaborate closely with Design, Process Engineering, Quality, and Manufacturing teams.

Knowledge, ability and skills:

• Proficiency with LabVIEW, Python, and/or C/C#.
• Understanding of calibration, SPC, MSA (GR&R), and Cpk.
• Develop engineering test procedures and specifications.

Minimum previous experience/qualification:

Required

• Bachelor’s degree in Electrical, Mechanical, Optical, Computer Engineering, or related field.
• 3 years of experience in test engineering or manufacturing test development.
• Demonstrated ability to translate specifications into test requirements and acceptance criteria.
• Experience with optical, electro-optical, or sensor-based products.
• Must be authorized to work and reside in the US and must be eligible for any required authorizations from the U.S. Government to conform with but not limited to U.S. export control regulations (ITAR).

Preferred

• Master’s degree in a related engineering discipline.
• Experience supporting EV/DV/PV test phases.
• Familiarity with optical materials, coatings, and metrology.
• Experience scaling test solutions from prototype to production.
• Experience with version control systems and test data visualization tools.
