Responsibilities

Design, assemble, and test rapid prototypes of novel X-Engine sub-systems, combustors, seals, or hybrid integration components
Perform hands-on fabrication using in-house machine shop, additive manufacturing (metal + polymer), and advanced assembly techniques
Run experiments on single-cylinder research engines, modified multi-cylinder demonstrators, or subscale Skunkworks test articles
Collect and analyze high-speed data (pressure traces, high-speed video, emissions, vibration) to validate bold design choices
Iterate designs weekly — CAD → print/machine → test → learn → repeat
Support classified / customer-funded fast-track projects (U.S. citizenship or permanent residency often required for certain tasks)
Collaborate across mechanical, thermal, combustion, controls, and materials boundaries
Document key findings in concise memos / one-pagers to influence long-term architecture decisions

Qualification

Mechanical EngineeringHands-on PrototypingCAD SkillsAdditive ManufacturingInternal Combustion EnginesHigh Tolerance for AmbiguityCollaboration Skills

Required

Pursuing B.S., M.S. or Ph.D. in Mechanical Engineering, or closely related field (rising junior or above preferred)
Demonstrated hands-on prototyping experience (Formula SAE, personal projects, research labs, rocketry, robotics, etc.)
Strong CAD skills (SolidWorks, Fusion 360, or similar)
Comfortable in a machine shop / hands-on lab environment (mill, lathe, 3D printing, basic welding helpful but not required)
U.S. person status (citizen or permanent resident) — many Skunkworks activities involve defense-related hardware
High tolerance for ambiguity + bias toward action

Preferred

Prior work with internal combustion engines, rotaries, or high-performance power systems
Exposure to additive manufacturing (especially metal DMLS / binder jetting)
Combustion, thermodynamics, or high-speed data acquisition experience
Experience with rapid controls prototyping (dSPACE, Speedgoat, Arduino/RPi for quick closed-loop demos)
Aerospace/defense project background (UAVs, hybrid propulsion, DARPA-style challenges)
Personal projects involving extreme environments, fuels, or unconventional engines
