Senior GNC Engineer

Los Angeles Metropolitan Area, California

$220,000 – $300,000 + Pre-IPO Equity + Outstanding Benefits

Relocation Assistance Available | Active TS/SCI Clearance Required

Own the Guidance, Navigation & Control systems behind next-generation spacecraft.

Are you a Senior GNC Engineer with experience developing Guidance, Navigation & Control systems for spacecraft? Do you enjoy solving complex guidance, navigation and control challenges that push the boundaries of autonomous spaceflight? Do you want to own technology that directly influences mission success from concept through flight? If so, this opportunity may be the right next step for you.

This engineering-led organisation is developing advanced spacecraft for demanding orbital missions where agility, autonomy and performance are critical. Engineers work in small, highly capable teams with genuine ownership across spacecraft architecture, flight software, simulation and mission performance. Ideas move quickly, technical decisions are made by engineers and every individual has the opportunity to influence the final product.

The Senior GNC Engineer will lead the development of spacecraft Guidance, Navigation & Control systems, taking ownership of vehicle guidance, control algorithms and mission performance throughout the complete engineering lifecycle.

As the Senior GNC Engineer your responsibilities will include

• Developing spacecraft Guidance, Navigation & Control algorithms from concept through flight
• Designing guidance, navigation, control and state estimation solutions for advanced spacecraft
• Supporting flight software, simulation, mission analysis and spacecraft integration activities
• Influencing spacecraft architecture and multidisciplinary engineering decisions
• Mentoring engineers while driving technical excellence across the GNC team

As the Senior GNC Engineer you will bring

• Active Top Secret clearance with SCI eligibility
• Experience developing spacecraft Guidance, Navigation & Control systems
• Strong MATLAB and C++ capability with flight software or control systems experience
• Knowledge of orbital mechanics, flight dynamics, mission analysis or spacecraft operations
• Strong technical leadership, analytical thinking and problem-solving capability

The Senior GNC Engineer will play a key role in shaping the next generation of advanced spacecraft, influencing vehicle capability, mission success and flight performance from day one. Alongside meaningful pre-IPO equity, relocation support and outstanding benefits, this role offers exceptional technical ownership, exposure to cutting-edge spacecraft development and clear opportunities to progress into Principal Engineer, Chief Engineer or Technical Director positions.

All successful applicants will be contacted within two working days.
