Who We Are
At Firestorm, we’re on a mission to revolutionize how defense solutions are designed and delivered. Our goal is to empower U.S. ally nations to effectively deter aggressors—regardless of their defense budget—through innovative, cost-efficient technologies. We call this vision “democratized deterrence.” As a VC-backed company at the intersection of defense and Silicon Valley, we’re pioneering the development of mission-adaptable aerial vehicles that put power back into the hands of operators. By prioritizing operator effectiveness, we’re pioneering a new era of aerial vehicle design. We aim to upend the traditional defense procurement model by delivering world-class capabilities at a fraction of the usual cost. Join us at Firestorm as we redefine defense procurement, making cutting-edge technology accessible to all at a fraction of the cost.
About the Role
At Firestorm, we are building autonomous aerial systems that operate where they are needed most, when they are needed most. Our mission requires speed, ingenuity, and a relentless commitment to engineering excellence. We move fast, test constantly, and deliver capability that performs in the real world, not just in simulation.
We are looking for a Controls Engineer who is excited to build, test, and deliver high-performance autonomous flight systems. You will own the design, implementation, and validation of flight-control algorithms for our Unmanned Autonomous Systems, blending deep control-systems expertise with startup-level ownership and hands-on testing. You will architect control solutions, build and refine models and simulations, and drive flight-test workflows from first flight through rapid iteration. This is not a theory-only role. You will see your work fly, assess real-world behavior, tune performance in the loop, and directly influence vehicle capability. You will help define technical standards, contribute to a high-integrity engineering culture, and shape how autonomy is deployed in demanding operational environments.
If you want to build systems that matter, own your work end to end, and be part of a team that values bold thinking grounded in rigorous engineering, Firestorm is the place to do it.
What You’ll Do
- Define control-system architecture and requirements for fixed-wing and autonomous aircraft, including primary flight control, energy management, and mode logic
- Design and implement control and estimation algorithms that account for actuator limits, sensor noise, timing, and real-world system constraints
- Model dynamical systems, develop accurate plant models, and validate them using flight-test data and simulation environments
- Lead system identification and aerodynamic model refinement based on real flight data
- Develop robust, fault-tolerant, and graceful-degradation control strategies for reliable autonomous operation
- Use simulation, SIL and HIL testing, Monte Carlo analysis, and system-performance tools to verify and validate flight-control and estimation software
- Design and execute flight-test plans, analyze telemetry and logs, tune controllers, and rapidly iterate based on real-world performance
- Integrate navigation and estimator outputs, including GPS-denied or alternative navigation solutions, into control architectures
- Collaborate closely with autonomy, avionics, embedded software, and flight-test teams to ensure seamless full-system performance
- Participate in system design reviews, safety assessments, and documentation to support high-integrity engineering practices
- Troubleshoot and resolve issues across simulation, ground testing, and flight operations
- Contribute to technical standards, code reviews, and continuous improvement in controls and GNC development processes
- Stay current with advances in controls, GNC, robotics, and autonomous systems and apply new techniques where beneficial
- Take ownership from concept through deployment in a startup environment where speed, rigor, flight testing, and accountability matter
Required Qualifications
- Bachelor’s degree in Robotics, Computer Science, Engineering, or related field
- 3+ years of experience in aerospace vehicle GNC development, simulation, & applied controls
- Experience building and tuning control systems for robotics, autonomy, or flight vehicles
- Proficiency in C++, Python, and MATLAB or Octave
- Strong foundation in classical and modern control theory
- Experience with system modeling and test-based validation
- Ability to evaluate flight data, debug issues, and communicate findings across teams
- Excellent communication and documentation skills
- U.S. Citizenship required due to ITAR regulations
Preferred Qualifications
- Masters degree or Ph.D in Robotics, Computer Science, Engineering, or related field
- 5+ years of experience in aerospace vehicle GNC development, simulation, & applied controls
- High proficiency in C or C++, Python, and MATLAB or Simulink or Octave
- Experience with estimator development such as EKF, UKF, or complementary filters
- Experience with GPS-denied or alternate navigation technologies
- Hands-on development on PX4 or ArduPilot or ArduPlane platforms
- Experience running flight-test campaigns and tuning flight controllers
- Experience flying RC fixed-wing aircraft
- Ability to clearly communicate control-system concepts to engineers outside your discipline
Work Environment
- Based at our Headquarters in San Diego, CA
- We welcome candidates who are local or open to relocating; relocation assistance is available and may be included in the offer package where appropriate
- Must be able to lift up to 30 lbs. and wear appropriate PPE [as required]
- Willingness to travel up to 10% domestically for testing and demonstrations
- Ability to work flexible hours and travel to various testing locations as needed
