Senior GNC Engineer at Astro Mechanica in San Francisco, CA

ABOUT US: Astro Mechanica is a vertically integrated aerospace company building a faster, more connected future. Our mission is to democratize high-speed flight by making supersonic travel flexible, accessible, and sustainable. We believe that rapid, on-demand, point-to-point global mobility will become the new standard for moving people and goods across the planet. To achieve this, we are integrating our advanced airframe and engine technologies—which include Duality™, our proprietary dual-use propulsion system—with a new flight operations model to make supersonic transport as efficient and economical as commercial air travel is today. In the near term, we are developing adaptable, high-speed systems to close aircraft performance gaps for the United States government. 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 engineer who wants real ownership over the guidance and control systems of a clean-sheet autonomous aircraft. You’re comfortable working from first principles, collaborating tightly with propulsion, structures, and avionics, and making practical tradeoffs to get hardware 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 - Develop 6-DOF dynamics simulation models used for 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 robotics, aerospace engineering, electrical engineering, or related discipline - 5+ years of professional experience in GNC development for an aerospace or autonomous vehicle program - Experience with dynamics, modeling, and simulation - Experience with software development best practices - Experience in algorithm design for autonomous vehicles - Experience in fly-by-wire control design for aircraft - Experience with Rust, C++, Python, or other relevant software languages. - Experience and/or an interest in mentoring junior engineers on GNC work and concepts - Experience communicating to teams of different disciplines about implications of GNC on their work and vice versa - Interest and drive to work on all aspects of GNC stack - Ambition to work in a fast-paced environment PERKS & BENEFITS: - Comprehensive medical, dental, and vision insurance, including Flexible Spending Accounts (FSA) - 401(k) program and transparent stock option plan - Self-managed and flexible time-off policy, including PTO, paid holidays, and sick time - Flexible work environment ADDITIONAL INFORMATION: At Astro Mechanica, we highly value in-office work to foster collaboration and strengthen our company culture.
