Senior Integration and Test Engineer

About this position

Attalon is a U.S.

-based aerospace and defense technology company formed through the 2025 carve‑out of Coherent's Aerospace & Defense division by Advent International. Attalon designs and manufactures mission‑critical optical systems, precision coatings, and advanced laser subsystems for ISR&T, space, missiles, and directed energy applications.

As an Optical Integration and Test Engineer, you will utilize optical engineering theory in the conceptual design, development, and testing of optical components, sub‑assemblies, and systems. This position will be located at our Tustin, CA site where we design and manufacture optical systems for a variety of defense and space applications. The role will be heavily involved in the initial product development phase to ensure that products are testable and manufacturable to the requirements specified by the design engineering team.

Significant hands‑on involvement will be required in the design and operation of optical metrology systems that verify and validate that the performance of our products meets customer requirements. You will investigate, identify, and resolve engineering problems on prototype builds and provide a smooth transition into routine production.

For California, the salary range for this position is: $84,295–$144,072. This range is a general guideline; compensation may vary based on responsibilities, experience, education, skills, and market conditions.

• Apply in-depth and diversified knowledge of optical engineering design theory and manufacturing engineering principles, practices, and methods.
• Provide support to the manufacturing team in the development and improvement of fabrication processes and methods, and develop new optical metrology and testing techniques.
• Develop and implement test procedures; evaluate and select appropriate test methods and instrumentation; understand full breadth of specification used to characterize optical surfaces, sub‑assemblies, and systems.
• Draft acceptance test procedures and review data to verify compliance with customer requirements and specifications.
• Apply quantitative analysis to determine root cause of technical issues related to the fabrication, assembly, and testing of optical components and systems.
• Provide hands‑on technical direction during integration and assembly of optical components into related mechanical hardware.
• Evaluate manufacturability of optical designs and provide feedback to the internal design team.
• Review customer requirements to propose and implement design‑based solutions to meet specific application needs.
• Mentor other engineers in alignment methods, error budgets, error analysis, and tools.

• BS or MS in optical engineering, physics, or an equivalent technical discipline.
• A minimum of 5 years of related work experience.
• Hands‑on experience with optical testing (interferometry, infrared testing, laser alignment stations, imaging quality analysis, MTF, ensquared/encircled energy).
• Knowledge of optical theory, aberration analysis, and optical design.
• Working knowledge of radiometric measurement techniques, photodetectors, and electronics is desirable.
• Basic knowledge of optical fabrication techniques for spheres, aspheres, and diamond‑turned optics.
