About the Job

Requirements

  • Bachelor's, Master's, or PhD in Aerospace Engineering, Electrical Engineering, or a related field.
  • 5+ years of experience in navigation algorithm development, analysis, and validation for aerospace or high-performance dynamic systems.
  • Strong background in estimation theory, including Extended Kalman Filters (EKF) and multi-sensor fusion.
  • Experience with inertial navigation systems (INS) and integration with external aiding sources such as GNSS, star trackers, or similar sensors.
  • Familiarity with alternative navigation (alt-nav) techniques for GPS-denied environments.
  • Proficiency in modeling and simulation tools such as MATLAB/Simulink or equivalent.
  • Experience with 3DOF and 6DOF simulation environments and real-time implementation of navigation algorithms.
  • Strong understanding of sensor error modeling for IMUs, star trackers, and related sensors, and calibration techniques.
  • Familiarity with flight software integration and real-time embedded systems.

Responsibilities

  • Design and develop navigation algorithms for high-speed flight vehicles, including inertial navigation and alternative navigation methods.
  • Develop and implement multi-sensor fusion architectures using Extended Kalman Filters and related estimation techniques.
  • Integrate data from IMUs, star trackers, GNSS when available, and other onboard sensors to provide robust, high-accuracy state estimation.
  • Work closely with avionics, flight sciences, and flight software teams to integrate navigation algorithms into real-time embedded systems.
  • Conduct modeling, simulation, and analysis to evaluate navigation performance, error growth, and robustness under GPS-denied and degraded conditions.
  • Support hardware-in-the-loop testing, flight testing, and post-flight analysis, translating results into system-level improvements.
  • Characterize sensor performance, biases, and error sources to inform filter design and tuning.
  • Develop tools and frameworks for navigation algorithm development, verification, and validation.
  • Mentor junior engineers and contribute to best practices in navigation and estimation.
  • Partner closely with program leadership to make technical trades aligned with mission success.

About the Company

Castelion

Designs and manufactures hypersonic strike weapons

Castelion designs, tests, and manufactures hypersonic strike weapons for the U.S. military, aiming to deter future wars with fast, credible, non-nuclear deterrence. Its flagship Blackbeard is a low-cost, mass-producible hypersonic missile compatible with HIMARS/MLRS, built in-house with solid rocket motors, propellant, and a real-time, hardware-isolated flight computer. The company uses vertical integration and a rapid test-and-iterate cycle, with frequent flight tests and Project Ranger, a 1,000-acre facility in New Mexico to scale production. It competes with traditional defense primes on speed and cost, selling under government contracts and development awards to field advanced weapons at scale.
