Python
MATLAB
C/C++
Julia

Strong analytical and problem-solving skills with a systems engineering mindset
Desirable Experience

Spacecraft attitude determination and control systems (ADCS)
Extended Kalman Filters (EKF) and navigation algorithms
Reaction wheels, control moment gyroscopes, motors, or thruster control systems
Control algorithm development and optimisation
Mission design, trajectory analysis, and orbital mechanics
Early-stage spacecraft or vehicle concept development
Hardware-in-the-loop (HITL) and hardware-out-of-the-loop (HOOTL) testing
Flight software development for space applications
Experience supporting launch and on-orbit operations
What's on Offer

Equity participation opportunities
Comprehensive healthcare, dental, and vision coverage
Paid holiday allowance and parental leave
Life insurance and additional employee benefits
