Staff GNC Software Engineer

Описание вакансии

The future of aerospace and defense starts here.

Ursa Major was founded to revolutionize how America and its allies access and apply high-performance propulsion, from hypersonics to solid rocket motors, satellite maneuvering and launch. We design and deliver propulsion and defense systems that solve the most urgent and critical national security demands.

Our products and technologies require an extraordinary team. A team that will mold tomorrow’s technologies while deploying today’s best. We are an intrinsically motivated team that has a passion for solving problems and empowering each other every day to develop our skills, knowing that there is always room for growth.

As a GNC Software Engineer you will develop, implement, and validate guidance, navigation, and control algorithms in software for flight systems in aerospace and defense applications. This role translates GNC concepts into robust, flight-ready software, working across simulation, embedded implementation, and hardware-in-the-loop environments. You will own well-defined subsystems or features, and collaborate closely with systems, avionics, propulsion, and test teams to ensure GNC software meets performance, safety, and mission requirements.

Responsibilities:

• Design, implement, and maintain flight GNC software for aerospace applications
• Translate GNC requirements and models into efficient, reliable embedded software
• Develop and execute simulations to evaluate guidance, navigation, and control performance
• Support system integration, hardware-in-the-loop (HIL), and flight test activities
• Analyze test and flight data to assess performance and drive improvements
• Contribute to requirements definition, verification, and traceability for GNC functions
• Identify and mitigate technical risks through analysis, testing, and peer review
• Collaborate cross-functionally with systems, avionics, software, and test engineers
• Document designs, analyses, and test results for internal and external stakeholders

Required Qualifications:

• Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, Electrical Engineering, Computer Science, or related field
• Professional experience developing GNC algorithms or flight software for aerospace or defense systems
• Strong understanding of classical control, estimation, and vehicle dynamics
• Experience implementing algorithms in C/C++ or similar embedded languages
• Experience with modeling and simulation tools such as MATLAB/Simulink or equivalent
• Familiarity with real-time or embedded software development environments
• Ability to work effectively across disciplines and communicate technical concepts clearly
• Ability to work effectively in teams or individually

Desirable Experience:

• Master’s degree in a relevant engineering discipline
• Experience with navigation sensors (IMUs, GPS, star trackers, etc.) and state estimation techniques (e.g., Kalman filtering)
• Exposure to hardware-in-the-loop testing, flight testing, or operational flight systems
• Familiarity with safety-critical or regulated development environments (e.g., DO-178 or equivalent processes)
• Experience with Python or similar scripting languages for analysis and tooling
• Prior experience supporting aerospace or defense programs through integration and test phases
