Principal Optical Engineer

QinetiQ US is looking for a Principal Optical Engineer experienced in electro-optic/infrared (EOIR) imaging sensor optical design, laboratory optical characterization, and prototype integration with a willingness to learn new skills to join our team.

In this role you will contribute directly to products and systems ensuring our Warfighters have overmatch against our adversaries and our Homeland is secure. You'll support programs to provide our customers with capabilities like long-range optics for scout surveillance and fires support, body-worn EOIR sensors, fire control, and more— you'll help provide the sensing capability that enables the 'observe' stage of the OODA (observe, orient, decide, act) loop.

You will work with key technologies, including:

  • Multi-band visible and infrared imaging optics including near infrared NIR, shortwave (SWIR), midwave (MWIR), and longwave (LWIR)
  • EOIR sensors
  • Tactical lasers, Class 1–4
  • Optical boresight and stabilization

Success in this role is defined as delivering robust EOIR optical designs, guiding prototype integration, and collaborating effectively across engineering disciplines to transition systems into production.
