This is a cross-disciplinary role at the seam where optics, electronics, mechanisms, and control software meet: you will own the electrical interfaces to opto-mechanical hardware, the acquisition/tracking/pointing (ATP) control loops that close the link, and the payload-to-platform interfaces that make the terminal a well-behaved guest on its host vehicle. Develop and specify the electronic interfaces to opto-mechanical elements — fast steering mirrors, gimbals, Risley prisms, focus and shutter mechanisms, TECs, and photodetectors — including drive electronics, sensor conditioning, encoder and position feedback, and the timing/synchronization architecture between them.
