The Senior EO/IR Systems Engineer will play a primary systems engineering role. The successful candidate will be responsible for sophisticated Electro-Optical (visible-NIR), SWIR, MWIR, and LWIR reflective and refractive optical imaging payload development, integration, and design verification test (DVT) plan development and implementation. This role supports cutting-edge technological ISR (Intelligence, Surveillance, and Reconnaissance) and ISR-T surveillance product development through the NPI (New Product Introduction) process, spanning from early prototyping to full market launch. Key responsibilities include specifications and requirements development, characterization, trade studies, tolerancing, radiometric modeling and analysis, system integration, testing, and image quality evaluation.
