Powertrain Cfd Engineer Jobs (NOW HIRING)

As a Flight Sciences Engineer at Elroy Air, you will own performance analysis, flight dynamics, and configuration trades across our hybrid-electric lift+cruise VTOL program. You will be the analytical backbone of the vehicle team — reasoning across hover, transition, and cruise regimes, and working directly with propulsion, structures, and controls engineers to drive decisions from early concept through certification.

• Own vehicle performance modeling across hover, transition, and cruise: mission analysis, hybrid-electric energy management, climb optimization, and range/endurance trades
• Build and maintain 6-DOF flight dynamics models for a lift+cruise configuration: aero database construction through the transition corridor, rotor-wing interaction modeling, stability derivatives, and trim analysis in hover, transition, and cruise
• Contribute to vehicle design trades: feed flight sciences insight into OML shaping, drag reduction, control surface sizing, and flight controls architecture to close performance and handling qualities requirements
• Derive external flight loads across the operational envelope and collaborate with the structures team to define limit and ultimate load cases, support fatigue analysis, and feed aeroelastic models
• Support flight test planning, instrumentation requirements, and post-flight data reduction and analysis; correlate measured performance against analytical predictions
• Build and improve simulation environments used for envelope expansion, handling qualities assessment, and controls development
• Partner with propulsion and power teams to integrate hybrid-electric powertrain models into mission analysis; define power-required envelopes and binding constraints across the flight profile
• Contribute to certification planning by authoring compliance analyses, performance substantiation reports, and supporting V&V documentation

• B.S. or M.S. in Aerospace Engineering or a closely related field
• 5+ years of meaningful hands-on experience in flight sciences, vehicle performance, or flight dynamics
• Proficiency in vehicle performance modeling: energy-based methods, point-mass and full 6-DOF simulation, power-required/available analysis
• Experience building or working with aerodynamic databases and stability derivative sets for flight simulation or loads analysis
• Familiarity with flight test methods: test card development, FTI requirements, data reduction, and prediction-to-flight correlation
• Strong programming skills in Python and/or MATLAB for analysis, post-processing, and tool development
• Solid understanding of fixed-wing, rotary-wing, or hybrid lift+cruise vehicle aeromechanics
• Working proficiency with aerodynamic analysis tools across fidelity levels — from low-order methods (panel codes, blade element, XFOIL) through mid-fidelity (RANS CFD): sufficient to set up runs, interpret results, and interface with dedicated CFD engineers
• Clear technical communication skills: able to distill complex analysis into concise summaries for engineering and program leadership
