What you need
- 1–3 years of relevant experience in control systems, estimation theory, flight dynamics, orbital mechanics, or simulation-driven validation
- Some hands-on experience with Python, including scripting and data analysis
- Familiarity with MATLAB and/or Simulink sufficient to run simulations and analyze numerical results
- Exposure to C++; ability to read and follow flight software code with guidance
- Foundational understanding of control systems theory (e.g. closed-loop dynamics, PID controllers, or state-space concepts)
- Introductory knowledge of orbital mechanics (e.g. Keplerian orbits, reference frames, coordinate transformations)
Nice to have
- Experience writing automated test frameworks or continuous integration pipelines for embedded or real-time software
- Familiarity with spacecraft sensors and actuators for attitude determination and control systems including star trackers, IMUs, reaction wheels, magnetorquers, or thrusters
- Experience with hardware-in-the-loop (HIL) or software-in-the-loop (SIL) test environments
- Exposure to spacecraft telemetry tools, ground software, or mission operations environments
- Knowledge of estimation theory
Worth weighing
- No salary listed
- Willing to work from office about 80% of the time
