About the role
Astro Mechanica's standard text
ABOUT US:
Astro Mechanica is a vertically integrated aerospace company developing a scalable technology platform to power critical infrastructure, mission operations, and the future of flight. We apply aerospace engineering and quality standards across our products, delivering high performance, reliability, and efficiency for the most demanding operating environments. Astro Mechanica is backed by leading venture and strategic investors, including Andreessen Horowitz (a16z), Giant Step Capital, United Airlines Ventures, and Voyager Ventures.
WHO WE ARE:
We’re a team of passionate engineers dedicated to advancing aerospace. We’re generalists with specialist depth, united by a flat structure and a shared obsession with building things that work well. We move fast, stay pragmatic, and let engineering excellence speak louder than hierarchy.
WHO YOU ARE:
You're a GNC software engineer who wants real ownership over the guidance and control systems of a clean-sheet autonomous aircraft. You work from first principles, you write the simulation and flight code yourself, and you work closely with hardware and software teams to get the aircraft flying. You care deeply about how systems behave in the real world—not just in simulation—and you’re motivated by building control architectures that are robust, testable, and ready for flight.
WHAT YOU’LL DO:
- Develop and implement guidance, navigation, and control systems for our products
- Engage in multi-disciplinary aircraft trades and help define the overall system architecture
- Build and maintain 6-DOF dynamics and simulation models used for control design, analysis, and validation
- Develop tooling to automate control design, monte carlos, and simulation validation
- Work closely with peers across engineering disciplines to define the control schemes and mechanisms for our products
- Support flight and ground test operations
- Conduct post flight/test reviews and correlate performance with analysis for continuous improvement on predictions
WHAT WE’RE LOOKING FOR:
- Master’s degree or PhD in aerospace engineering, software engineering, robotics, electrical engineering, or related discipline
- Professional experience in GNC development for an aerospace or autonomous vehicle program
- Strong background in flight dynamics, modeling, and simulation
- Proficiency in Rust, C++, or a comparable systems language, plus Python for analysis and tooling
- Experience with software development best practices such as version control, code review, testing, and CI
- Ambition to work in a fast-paced environment
