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 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:

* Experience working with **Onshape** (CAD)
* Experience working with **state-of-the-art EWIS tools**, including schematics and scripting
* Professional background in the **aerospace or automotive industry**, or similarly complex, safety-critical environments
