Flight Sciences Engineer (eVTOL)

Location: Byron, California; hybrid workplace. Applicants must be legally authorized to work in the United States as a U.S. citizen or lawful permanent resident.

Company

hirify.global develops aerospace and logistics technology, including the hybrid-electric Chaparral lift+cruise VTOL aircraft for defense, commercial, and rapid-response applications.

What you will do

• Own vehicle performance modeling across hover, transition, and cruise, including mission analysis, energy management, climb optimization, and range/endurance trades.
• Build and maintain 6-DOF flight-dynamics models, aerodynamic databases, stability derivatives, trim analyses, and rotor-wing interaction models.
• Support vehicle design trades involving outer mold line shaping, drag reduction, control-surface sizing, and flight-controls architecture.
• Derive external flight loads, define limit and ultimate load cases with the structures team, support fatigue analysis, and contribute to aeroelastic models.
• Plan flight tests, define instrumentation requirements, analyze post-flight data, and correlate measured performance with analytical predictions.
• Develop simulation environments and certification documentation for envelope expansion, handling-qualities assessment, controls development, and V&V.

Requirements

• B.S. or M.S. in Aerospace Engineering or a closely related field.
• 5+ years of hands-on experience in flight sciences, vehicle performance, or flight dynamics.
• Experience with energy-based methods, point-mass and full 6-DOF simulation, and power-required/available analysis.
• Experience with aerodynamic databases, stability derivatives, flight simulation or loads analysis, and flight-test methods.
• Strong Python and/or MATLAB programming skills for analysis, post-processing, and tool development.
• Working proficiency with aerodynamic analysis tools from low-order methods through RANS CFD, plus clear technical communication skills.

Nice to have

• Experience with eVTOL, tiltrotor, or lift+cruise configurations and transition-corridor analysis.
• Hybrid-electric propulsion performance modeling, battery-sizing trades, and BSFC/TSFC integration.
• Rotor or propeller design, internal flows, aeroelasticity, or structural loads experience.
• Handling-qualities assessment using ADS-33 or FAA/EASA equivalents.
• Experience with JSBSim, Simulink/FlightGear, FAA Part 23 or Part 27, or EASA SC-VTOL certification.

Culture & Benefits

• Competitive salary and equity ownership in a rapidly growing aerospace startup.
• Comprehensive medical benefits, 401(k) with company contribution, and Roth IRA.
• Free daily lunch provided onsite and flexible time off.
• Three months of paid parental leave and an employee assistance program with 24/7 support.
• High-impact environment with significant ownership, autonomy, career growth, and internal advancement opportunities.
• Collaborative, inclusive workplace with reasonable accommodations and a focus on building aerospace and logistics technology.
