Senior Harness Engineer; EWIS

We are looking for a Senior / Lead Harness Engineer (EWIS) who takes ownership, thinks in aircraft-level systems, and enjoys finding pragmatic, fast paths forward in a startup environment.

In this role, you are not “just designing harnesses” — you are shaping how the aircraft is wired
, from early architecture decisions through prototype builds and into manufacturable solutions. You will act as the EWIS focal point
, interfacing closely with systems, avionics, structures, propulsion, and manufacturing, and helping the team converge on robust, lightweight, and producible solutions.

EWIS is a core backbone of the aircraft and a source of truth for manufacturing. Attention to detail matters — but so does knowing when to move forward, iterate, and improve on the next build.

• Own and drive EWIS design and interface requirements across the aircraft (electrical wiring interconnect system)
• Design, optimize, and evolve aerospace harnesses across the full lifecycle, from early concept through prototype and production
• Create and maintain complex harnesses and assemblies in CAD
  , including routing and integration at aircraft level
• Derive fully dimensioned 2D technical drawings to support manufacturing, inspection, and certification needs
• Actively support manufacturing, integration, and test activities
  , including hands‑on involvement during prototype builds
• Support system development from concept to production
  , working closely with avionics, propulsion, structures, and operations
• Identify and resolve design, manufacturing, and assembly issues in a pragmatic, solution‑oriented manner

• Degree in electrical engineering or a comparable level of relevant professional experience
• Solid experience with electrical equipment integration
  , including grounding and bonding
• Good understanding of manufacturing drawings and harness documentation
  , including lacing, marking, and BOMs
• Proficiency working with state‑of‑the‑art EWIS tools
• Proficiency in CAD tools
  , with basic familiarity with PDM/PLM systems
• Strong analytical and problem‑solving skills
  , combined with a pragmatic, target‑oriented work style
• Clear and effective communication skills across disciplines and seniority levels
• Eligibility to work in Switzerland (EU/EFTA or equivalent work authorization)

• Experience working with Onshape (CAD)
• Experience working with Altium Designer (CAD), including schematics and scripting
• Professional background in the aerospace or automotive industry
  , or similarly complex, safety‑critical environments
