Job Description

Principal GNC Engineer | Spacecraft Controls

Boulder, Colorado | On-Site

$230,000 – $270,000 + Pre-IPO Equity + Benefits

U.S. Person / Export-Control Eligibility Required

Are you an experienced spacecraft GNC engineer ready to shape the control architecture of next-generation space vehicles? Have you developed guidance, navigation or control systems for satellites, spacecraft or other complex flight platforms? Would you enjoy combining technical leadership with hands-on engineering, seeing your designs progress from simulation into real missions? If so, this opportunity may be the right next step for you.

This rapidly growing space technology organisation is developing advanced spacecraft for challenging orbital missions. Engineers work closely across disciplines, with the freedom to solve complex problems, influence vehicle design and accelerate hardware from concept towards flight.

The Principal GNC Engineer will take technical ownership of spacecraft guidance and control architecture, developing robust flight capabilities while influencing future vehicle designs and missions.

As the Principal GNC Engineer your responsibilities will include

\n
• Architecting spacecraft GNC systems , including flight software, simulation and verification environments
\n
• Developing guidance, navigation and control algorithms for spacecraft and orbital vehicles
\n
• Performing control-system modelling, stability analysis and performance verification
\n
• Developing MATLAB/C++ simulations and flight software , supporting integration and testing
\n
• Providing technical leadership , mentoring engineers and supporting spacecraft flight operations
\n

As the Principal GNC Engineer you will bring

\n
• Extensive experience in spacecraft GNC, flight dynamics or spacecraft control systems
\n
• Strong understanding of control theory, dynamic modelling and time/frequency-domain analysis
\n
• Experience with MATLAB, Simulink, C++ or spacecraft simulation tools
\n
• Proven involvement in GNC architecture, algorithm development, verification or flight implementation
\n
• Ability to solve complex engineering problems and guide technical decisions across teams
\n

Experience with satellites, upper stages, landers, orbital manoeuvres or spacecraft operations would be particularly valuable.

The Principal GNC Engineer will have genuine technical authority, influencing spacecraft architecture while remaining closely involved in design, software development, testing and flight performance.

With $230,000–$270,000 base salary, pre-IPO equity and comprehensive benefits , this offers significant engineering ownership, long-term technical progression and the opportunity to shape future space missions.

All successful applicants will be contacted within two working days.
