Wire Harness Technician (EWIS)

Here at The Exploration Company, we are developing, producing, and operating Nyx, a modular and reusable space orbital vehicle that can eventually be refuelled in orbit and that can carry cargo - and potentially humans in the longer run.

To support this mission, we are bringing harness manufacturing in-house and are looking for a Wire Harness Technician to help industrialize, build, and validate high-reliability electrical harnesses used across the Nyx avionics and test campaigns.

In this role, your scope will be continuously evolving. Day-to-day you will help translate harness design outputs into robust manufacturing processes and deliver flight-like and test harnesses with strong quality, repeatability, and documentation.

Key Responsibilities

In your capacity as a Wire Harness Technician, your responsibilities will typically include:

Manufacturing & Assembly Execution

• Build electrical harnesses (development, qualification, and test harnesses), including cut/strip, crimp, splice, solder (where applicable), lacing/tie, over-braid/shield terminations, labeling, and final assembly.

• Support batch-by-batch production for test campaigns and verification activities (e.g., shock/vibration, EMI/EMC, TVAC), coordinating readiness of parts, tooling, and work instructions.

Cross-functional Collaboration

• Work closely with harness design and integration stakeholders to ensure manufacturability (DFM), clarity of drawings, and alignment between wiring diagrams and physical assembly.

Documentation & Traceability

• Maintain “as-built” records, deviations, rework logs, and configuration/serial tracking for harnesses and critical components.

What we would love to see from you

For the Wire Harness Technician role, you ideally bring experience with the following:

• Technical vocational training (Ausbildung) in electrical, electronic, or mechanical fields (e.g. Elektroniker, Mechatroniker) or equivalent hands-on experience.

• Strong hands-on experience with wiring harness manufacturing or cable assembly in high-reliability contexts (aerospace/space, aviation, motorsport, defense, medical, or similar).

• Ability to interpret harness drawings, wiring diagrams, BOMs, and connector tables; comfortable working from controlled documentation and detailed work instructions.

• Solid understanding of harness workmanship principles (crimp quality, strain relief, routing/bend radius, shielding/grounding practices, backshell assembly and torqueing, etc.).

• Practical troubleshooting skills (identifying pinning errors, shorts/opens, intermittent faults, damaged contacts, shielding issues, etc.).

• Experience using typical harness assembly tools (crimp tools, wire strippers, insertion/extraction tools, torque tools, soldering equipment when applicable).

• High attention to detail and manual dexterity, with a strong focus on quality and workmanship standards (preferably IPC/WHMA awareness).

• Ability to follow precise processes and work instructions while maintaining consistency and traceability during production.

• Comfortable working in a fast-paced production or test environment where priorities can shift based on integration and delivery needs.

• Team-oriented mindset with clear communication with engineering and quality teams when issues arise.

Nice to Have

• Familiarity with aerospace/space workmanship standards and inspection approaches (e.g., IPC-style workmanship, connector acceptance criteria, traceability practices).

• Experience with harness electrical test equipment and automated test report generation.

• Understanding of EMI/EMC-sensitive build practices (shield termination strategies, pigtail control, bonding/grounding considerations), aligned with the fact that harnesses support EMI/EMC test activities.

• Prior experience supporting test harness builds for environmental testing (vibration, thermal-vac, etc.).
