Harness Design Engineer

At Heart Aerospace we are developing 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. Our headquarters is based in Gothenburg, Sweden and we are now opening up a R&D hub in Los Angeles, which will focus on the advancement of Heart's hybrid-electric propulsion system and other key technologies.

Your mission

We are seeking a hands-on Harness Design Engineer to join our engineering team. This role combines electrical and mechanical design with prototype fabrication responsibilities. The ideal candidate will be comfortable taking a harness from concept to reality-selecting components, designing schematics and mechanical layouts, and building working prototypes for testing and integration into test setups and prototype aircraft.

Key responsibilities include but are not limited to:

• Design wiring harnesses for electromechanical systems, including schematic creation and 2D/3D routing layouts.
• Select appropriate wires, connectors, terminals, fuses, backshells, and other harness components
• Create detailed harness drawings and documentation (BOMs, pinouts, wiring diagrams, cable schedules).
• Fabricate, assemble, and install prototype harnesses for development and testing.
• Collaborate with cross-functional teams, including electrical, mechanical, software and systems engineers.
• Iterate designs based on test results, field feedback, or evolving requirements.
• Perform electrical and mechanical validation of harnesses (continuity, resistance, insulation, fitment, etc.).
• Manage fast prototype workshop with critical tools, wires, connectors, etc.
• Support transition from prototype to production, working with suppliers and manufacturing teams.

You'll Bring These Qualifications:

• 2+ years of experience in wiring harness design and fabrication.
• Strong understanding of electrical schematics, mechanical layout, and harness routing principles.
• Proficiency with ECAD tools such as Zuken, AutoCAD Electrical, SolidWorks Electrical, Altium, or equivalent.
• Proficiency with MCAD tools such as Siemens NX, SolidWorks, CATIA or equivalent.
• Hands-on skills in wire crimping, soldering, and harness assembly.
• Familiarity with electrical test equipment (multimeters, continuity testers, etc).
• Experience with design for manufacturability (DFM) and working with contract manufacturers is a plus.

These Qualifications Would Be Nice to Have:

• Working knowledge of wire harnessing standards in aerospace application (Mil standards, AS50881, DO-160, IPC/WHMA-A-620, and etc..)
• Experience with 3D harness routing in CAD assemblies.
• Knowledge of EMI/EMC best practices in cabling.

Education

• Bachelor's degree in Electrical Engineering, Mechanical Engineering, Mechatronics, or a related field-or equivalent experience.
