You'll be working on a national-security space program at one of the most respected engineering institutions in the world, on hardware that has to perform at the edge of what's physically possible. If you love building simulations of how real hardware actually behaves: motors, actuators, sensors, the things that make a spacecraft instrument point exactly where it needs to: this one is for you. You'll work onsite alongside a small, sharp team, helping prove out a precision-pointing space instrument before it ever flies. Your models tell the team what will work, what won't, and where the risk is. This is a hands‑on MATLAB/Simulink modeling role, not a paperwork or pure‑software job. If you'd rather be deep in the dynamics of a system than writing flight code, you'll feel at home here. What you'll do Build and maintain high‑fidelity Simulink models of electromechanical actuators and sensors — capturing how they really behave, not just the textbook version. Tune and validate your models against real testbed data so the team can trust them. Use those models to find risks early and help set requirements for the next version of the hardware. Create simpler "surrogate" models that plug into the bigger system simulation. Run quick‑turn studies (think 2–3 week sprints) and present what you found in clean plots and slides. Keep the project's main simulation healthy and stable for everyone else who depends on it. Sit in on vendor and hardware‑supplier reviews so your models match the real components. Required Skills Strong experience in MATLAB and Simulink Experience with precision pointing systems (or closely related: fine‑steering mirrors, gimbals, line‑of‑sight stabilization, servo/motion control). Background in space instruments, electro‑optical/IR systems, laser comm, telescopes, or seekers. Understanding of Signal Processing Active TS/SCI Clearance #J-18808-Ljbffr RESOURCE ASSOCIATES II
