GNC Software Engineer

The role

You will develop, integrate and validate flight software that enables autonomous operation of spacecraft. You will work with GNC and Flight Software engineers to deploy estimators, controllers, and state machines in real-time flight environments.

What you will do

• Develop and integrate GNC algorithms using model-based development processes
• Implement state machines and FDIR 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 test campaigns
• Develop unit tests and regression tests to ensure software reliability
• Collaborate with simulation, hardware, and Flight Software teams

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

Nice to have

• 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

Before you apply

• For U.S. Roles: applicant must be a U.S. citizen, lawful permanent resident of the United States (i.e. Green Card holder), or other protected individual
• For U.K. Roles: requires Baseline Personnel Security Standard (BPSS) checks and eligibility to obtain UK Security Clearance (SC)
• For Canada Roles: must obtain and hold a security clearance at the reliability status level, and pass security assessment for the Canadian Controlled Goods Program (CGP) and ITAR
