Lead Systems Engineer

We've been engaged by a fast-growing space situational awareness company to find an experienced Systems Engineer to lead the definition of active EO/IR system architectures from concept through flight test. Our client is building sophisticated space-based sensing systems that deliver actionable orbital intelligence. This is a rare opportunity to join early, help shape engineering culture, and take real ownership over payload systems that go to orbit. The Role: Define EO payload system architectures via detailed trade studies Model sensor performance and derive system requirements Own prototype sensor development in a lab environment Perform hands-on radiometric/geometric characterization and calibration of flight hardware (collimators, integrating spheres, interferometers, laser trackers, etc.) Author Interface Control Documents (electrical, mechanical, thermal, optical) Define on-orbit calibration sequences and support real-time operations Lead small engineering teams from concept through delivery What Our Client is Looking For: BS+ in engineering or a hard science Proven experience taking systems from concept through test and delivery Strong foundation in optical test methods, grounded in the underlying physics Experience with radiometry, MTF/PSF, boresight alignment, non-uniformity correction, and related payload analyses Proficiency in MATLAB/Python; familiarity with MODTRAN, SPIRITS, or AFSIM a plus Willingness to travel to test sites as needed Must be able to obtain and hold a U.S. security clearance Bonus Points: Laser systems / beam-steering experience Electro-mechanical control systems LiDAR/Radar signal processing on embedded platforms (FPGA/MCU) Optical modeling in Zemax or Code V Our client offers a competitive salary, benefits, and equity package, along with the chance to make a lasting mark on a mission-driven engineering team.
