Senior Turbomachinery Engineer

At Heart Aerospace we develop the ES-30, a regional hybrid-electric airplane with a capacity of 30 passengers, an electric zero-emission range of 200 km and an extended hybrid range of 800 km. Heart is targeting type certification of the ES-30 by the end of the decade.

We are expanding our R&D hub in Los Angeles, where we are advancing Heart’s hybrid-electric propulsion system.

Your mission

We are seeking a highly motivated Senior Turbomachinery Engineer to join our Propulsion team. You will lead the design and integration of the turbomachinery components, including the fuel system and pitch control system. You will interface across mechanical, thermal, electrical, and control systems to deliver a fully integrated and certifiable propulsion unit.

Key responsibilities include but are not limited to:

• Full ownership over design, fabrication, and certification of the hybrid powertrain.
• Lead the design of turbomachinery, including combustion systems, fluid analysis, high-speed rotating machinery, and similar.
• Lead and execute system-level tests, such as engine and propeller test stands.
• Collaborate with suppliers to ensure delivery of integrated, certifiable subsystems.

You'll Bring These Qualifications:

• 3+ years of professional experience working with propulsion components such as gas turbines, thermal management systems, propellers, and ancillary systems.
• Hands-on experience with propulsion or powertrain test stands, including instrumentation, controls, and mechanical assembly.
• Experience with CAD (e.g., Siemens NX), system integration, and PLM tools.

These Qualifications Would Be Nice to Have:

• Understanding of certification requirements (EASA CS-23/25 or FAA FAR Part 23/25).
• Knowledge of drivetrain dynamics, rotor balancing, or propeller aerodynamics.

Education

• Bachelor’s or Master’s degree in Mechanical, Aerospace, or Mechatronics Engineering (or similar).
