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.


Tasks



- **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



Requirements


required:




- 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)




advantageous:




- Professional background in the A
**erospace/UAV or automotive industry**
, or similarly complex, safety-critical environments

- Experience working with
**Onshape**
(CAD)

- Experience working with
**Altium Designer**
(CAD), including schematics and scripting
