Principal Robotic Controls Engineer

ABOUT THE ROLE

Join a defense technology team developing autonomous directed-energy systems. As the senior technical anchor for controls, you will shape precision pointing and tracking architecture, from theory and simulation through real-world hardware testing.

WHAT YOU'LL DO

• Design control architecture for coarse gimbals and fine steering mirrors, including bandwidth allocation, multi-rate operation, and stage handoffs.
• Develop Kalman, interacting multiple model, and nonlinear filters that fuse radar, EO/IR, and inertial data into latency-compensated aimpoint estimates.
• Build line-of-sight stabilization and jitter-rejection methods, including inertial stabilization, feedforward, and adaptive or notch filtering for structural modes.
• Allocate pointing error budgets across jitter, bias, latency, and atmospheric effects, then validate precision performance against dynamic targets in field tests.
• Model plants and identify system dynamics for gimbals, mirrors, and structures, using simulation and hardware-in-the-loop validation.
• Analyze stability and robustness under disturbances and parameter variation, and integrate controls with tracking, engagement sequencing, and safety logic.
• Deploy control algorithms to embedded targets, collaborate on kilohertz-rate loops, and compare field test results with simulation predictions.
• Provide technical review across controls and sensor integration, and mentor engineers through hands-on technical leadership.

WHAT WE'RE LOOKING FOR

• At least 10 years of experience closing loops on precision pointing, tracking, or stabilization hardware, with PhD-level depth in control theory and estimation.
• Proficiency in robust control, including H-infinity, mu-synthesis, and LQG, plus optimal estimation such as Kalman variants, IMM, and nonlinear observers.
• Experience shipping C or C++ control loops on embedded or RTOS targets, and working with MATLAB/Simulink and Python.
• Background in sensor fusion, multi-rate and sampled-data design, real-time hardware-in-the-loop validation, system identification, and structural dynamics.
• Ability to serve as the controls technical anchor on a small team. Directed-energy or high-energy laser experience and an active security clearance, or ability to obtain one, are advantages.
