Job description

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 400 km. Heart is targeting type certification of the ES-30 by the end of the decade.

Your mission

As part of the Flight Mechanisms team, you will be responsible for design, development, validation, and eventually certification of components including primary and secondary flight control actuators, propulsion and landing gear components, and environmental control (ECS) components. You will work with electrical, software, and mechanical engineers across teams to build and fly complex systems.

Key responsibilities

• The opportunity to exercise full ownership over the design, fabrication and test of novel flight components.
• You will lead the design of crucial subcomponents including gears, bearings, seals.
• Design, build and test components to environmental qualification standards such as DO-160G, MIL-STD-810, or similar.
• Work with a cross‑functional team developing electronic and software control systems.
