Sr Mechanical Design Engineer Jobs (NOW HIRING)

At Heart Aerospace, we're shaping the future of sustainable aviation with the ES-30, a regional hybrid-electric aircraft designed to carry 30 passengers with a 200 km all-electric, zero-emission range and an extended 400 km hybrid range. Heart is targeting type certification by the end of the decade.

Your Mission

As a Mechanical Design Engineer, Structures & Airframe, you will design, analyze, and develop aircraft structural components. You will collaborate cross functionally to the design of the fuselage, wing, and empennage, working with both composite and metallic materials, while gaining hands-on exposure to certified aerospace hardware development in a fast-paced, collaborative environment.

This is an exciting opportunity for a mechanical or aerospace engineer to contribute to the design and development of next-generation aircraft structures while building strong engineering fundamentals and growing into increased technical responsibility over time.

Key Responsibilities include but are not limited to:

• This role is a Responsible Engineer (RE) who focuses on the design and development of aircraft structural components.
• Create and release 3D CAD models, 2D drawings, and documentation using NX/Teamcenter or equivalent tools.
• Optimize structural performance for cost and mass.
• Perform structural analyses, hand calculations, and FEA activities with mentorship.
• Define structural requirements, specifications, and test plans.
• Own structural testing activities, data review, and documentation.
• Collaborate with manufacturing, quality, and test teams to resolve design and build issues.
• Participate in design reviews, continuous improvement and best practices.
• Learn and apply aerospace standards, GD&T, and manufacturing fundamentals.

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