Mechanical Design Engineer, Flight Mechanisms

Heart Aerospace is an electric aviation company focused on electrifying regional air travel through the development of battery-electric aircraft. The company is designing the ES-30, a 30-seat electric regional aircraft intended to serve short-haul routes with zero CO2 emissions, offering airlines a fundamentally lower-cost operating model compared to conventional turboprop or jet aircraft. Heart Aerospace also operates the X1 experimental aircraft as part of its development program to validate core technologies ahead of the ES-30's entry into service. The company's mission is centered on decarbonizing aviation, starting with regional routes where electric propulsion is most technically and economically viable. By targeting short-distance air travel, Heart Aerospace aims to eliminate direct carbon emissions on these segments while making regional connectivity more affordable for both operators and passengers. The company has secured investment from leading venture capital firms aligned with electrification and decarbonization goals, as well as strategic investments from major airlines that have also signed on as early customers. Heart Aerospace was founded in Sweden and has established a presence in the United States, with its listed address in Torrance, California. The company represents a new generation of aerospace manufacturers betting that advances in battery technology and electric drivetrains can transform commercial aviation, beginning with the regional segment where routes are short enough to make today's battery energy density practical.

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 include but are not limited

• 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 will a cross-functional team developing electronic and software control systems.

(This position can be hired as a Mechanical Design Engineer or Senior Mechanical Design Engineer )
