We are looking for a hands-on Prototyping Engineer to lead Astradyne’s product development and physical validation activities. This role is the bridge between design and reality: you will own the build-and-test cycle of our lightweight foldable solar panels, iterating quickly from concept to validated prototype, and providing technical support as products transition into small-series production.
You will work closely with the design team and external partners to ensure that new designs are physically sound, testable, and ready to scale.
Gross annual salary (RAL): €26.000 – €35.000
Key responsibilities
- Build, assemble, and test physical prototypes of lightweight foldable solar panels, including lamination, cell interconnection, and mechanical structures.
- Perform electrical testing and characterization of photovoltaic assemblies using tools such as multimeters, IV curve tracers, and custom test fixtures.
- Iterate rapidly on prototype designs in close collaboration with the design team, identifying failure modes and proposing practical improvements.




- Develop and document repeatable assembly and manufacturing procedures.
- Maintain organized and accurate technical records, including test reports, build logs, and bill of materials.
- Provide hands-on technical support during the transition to small-batch production, ensuring manufacturing quality matches prototype validation results.
- Contribute to DFM (Design for Manufacturability) reviews to ensure new designs are optimized for assembly and scale-up.

Essential qualifications
- 2–5 years of experience in a prototyping, product development, or hands-on hardware role.
- Proven hands-on mindset with a track record of building and testing physical products or assemblies.
- Solid proficiency in 3D CAD tools (e.G. SolidWorks) for design review and modelling.
- Good command of electrical testing instruments and measurement
- Strong attention to detail and ability to work methodically in a workshop/lab environment.
