Firestorm Labs - Democratize the fight with radically-affordable, mission-adaptable power for air, land, and sea. Backed by NEA.
About the role
As a Staff Propulsion Engineer at Firestorm, you will own the propulsion systems that power our sUAS platforms—from small piston and heavy-fuel engines to the fuel, induction, ignition, and exhaust architectures that surround them. You will be responsible for engine selection, integration, calibration, and qualification across Firestorm’s fuel-based aircraft, translating mission endurance and performance requirements into producible powerplant solutions.
What they're looking for
- Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or a related field (Master's degree preferred)
- 7+ years of experience in propulsion engineering, preferably with small piston engines, heavy-fuel engines, or small gas turbines
- Deep working knowledge of internal combustion fundamentals: thermodynamic cycles, AFR, combustion, knock, ignition systems, and exhaust
- Hands-on experience designing and operating engine test stands, including dyno instrumentation, fuel flow measurement, EGT/CHT instrumentation, and data acquisition
- Experience with EFI systems and ECU calibration (EFI Technology, MoTeC, Currawong, or equivalent)
- Experience with fuel system design across the full flight envelope—including altitude, attitude, and thermal effects on fuel delivery and pressure
More about this role
At Firestorm, we are building the future of expeditionary defense manufacturing and autonomous systems. Modern conflict has exposed a fundamental problem: the systems needed most by operators are often too expensive, too slow to produce, and too difficult to sustain at scale. Firestorm exists to change that.
We develop mission-adaptable aerial systems and deployable manufacturing infrastructure designed to put capability directly into the hands of the warfighter. From modular unmanned aircraft to xCell — our deployable microfactory — our goal is to make defense systems rapidly deployable, adaptable, and producible at the point of need.
We are looking for builders, operators, and problem-solvers who want to work on meaningful technology with real-world impact.
