GNC Engineer
Description
At OKSI, we believe in owning problems end to end — from first concept through final delivery. We see it through! If you're looking for a place where you can take real ownership, stretch your skills, a place to grow your career while owning meaningful, mission-driven work, this is where you belong.
OKSI is seeking a Guidance, Navigation, and Control (GNC) Engineer to design, develop, and validate GNC algorithms, flight software, and control systems for spacecraft and/or aerial vehicle platforms. The successful candidate will work across the full engineering lifecycle — from algorithm design and simulation through hardware integration, test, and on-orbit or flight operations — collaborating closely with cross-functional engineering teams, program management, and internal and external stakeholders.
What You'll Get To Do
Algorithm & Software Development
- Design and develop GNC algorithms for attitude determination and control, orbit determination and control, and precision pointing
- Design flight software, algorithms, and simulation products, and support spacecraft autonomy tools for constellation management
- Develop GNC software modules and interfaces in collaboration with software engineers, ensuring seamless integration with overall vehicle systems
- Implement designed flight control algorithms onto flight control system hardware
Analysis & Simulation
- Conduct spacecraft/vehicle dynamics analysis and perform simulations to evaluate system performance, stability, and accuracy
- Perform trade studies and recommend optimal GNC configurations, weighing factors such as power, mass, and cost
- Run hardware-in-the-loop (HIL), software-in-the-loop (SIL), and Monte Carlo simulations, including iron-bird analysis where applicable
- Define fault detection and response strategies for GNC subsystems
Hardware & Systems Integration
- Select GNC components and lead GNC subsystem design, including reaction wheels, thrusters, magnetic torquers, IMUs, star trackers, and gyroscopes
- Develop blended attitude solutions from multiple sensor data sources
- Collaborate with spacecraft, payload, and avionics engineers to define system requirements and ensure GNC compatibility and integration
