Job description

We are working with a hyper-scaling aerospace startup developing next-generation spacecraft technology, seeking a Spacecraft GNC Engineer to take ownership of critical guidance, navigation and control systems.

This is a hands-on opportunity to influence how a new spacecraft platform performs in orbit, working across attitude control, orbital dynamics, simulation and flight software. You'll have ownership across the full engineering life cycle, from initial algorithm development through to hardware testing and on-orbit operations.

Key Responsibilities

• Design and develop spacecraft attitude determination and control systems.


• Build and maintain 6-DOF simulations to evaluate spacecraft dynamics and performance.


• Develop state estimation, sensor fusion and orbital control algorithms.


• Integrate GNC algorithms into flight software and validate performance through hardware-in-the-loop testing.

Required Qualifications

• Experience in spacecraft GNC, ADCS or orbital dynamics.


• Strong understanding of attitude control, state estimation and dynamic systems.


• Experience developing and validating control algorithms.

Nice to Have

• Python, C++ or Rust.


• Monte Carlo analysis and 6-DOF simulation.


• Experience with spacecraft commissioning or on-orbit operations.

Why Consider This Opportunity?

Take ownership of the systems that determine how a new spacecraft operates in orbit, with significant autonomy and direct influence over technical decisions.

If you're a spacecraft GNC engineer looking to own more of the development lifecycle, we'd be interested in hearing about your experience.
