We are seeking a GNC Software Engineer to join our Guidance, Navigation, and Control (GNC) team. In this role, you will develop, integrate and validate flight software that enables autonomous operation of spacecraft. You'll work closely with GNC and Flight Software engineers to deploy estimators, controllers, and state machines in real-time flight environments, supporting missions from simulation through on-orbit or in-flight operation.
What You'll Do
Develop and integrate GNC algorithms using model-based development processes
Implement state machines and FDIR (Fault Detection, Isolation, and Recovery) logic for robust autonomous operations
Develop and maintain GNC software interfaces within the flight software architecture
Design, implement, and maintain software- and hardware-in-the-loop (SIL/HIL) test campaigns to validate GNC performance and reliability
Develop unit tests and regression tests to ensure software reliability
Collaborate with simulation, hardware, and Flight Software teams to support end-to-end GNC system integration and validation
Required Qualifications
2+ years of professional experience developing GNC software for spacecraft, UAVs, or other autonomous platforms
Hands-on experience implementing and testing estimators, controllers, and state machines
Experience with model-based software development and automatic code generation using MATLAB/Simulink
Proficiency in C++, Python, and MATLAB/Simulink
Experience developing unit tests, regression tests, and debugging software in simulation or embedded environments
Proficiency with Git version control and Linux-based development environments
Desired Qualifications
Bachelor's or Master's in Aerospace, Mechanical, Electrical, or Computer Engineering
Experience implementing FDIR strategies and autonomous mode management using state machines
Hands-on experience with software- and hardware-in-the-loop (SIL/HIL) simulation environments
Familiarity with continuous integration and continuous deployment (CI/CD) pipelines and automated software testing
Understanding of spacecraft attitude determination and control systems (ADCS), including sensors, actuators, and onboard estimation and control algorithms.
