VALENCIA, SPAIN · ON-SITE · UNPAID · 4 TO 6 MONTHS · PATH TO FULL-TIME

From concept to render to buildable engineering. You'll model components, assemblies and systems for real hardware — thermochemical reactors, energy systems and industrial enclosures. Your models turn into machined parts and fabricated assemblies that ship.

Who we are

We build and operate a portfolio of companies from a 4,000 sqm campus in Canggu, Bali, with 20+ years of company building across New York, London and Tokyo.

Zero-X develops thermochemical conversion and distributed energy systems, with 200+ systems live in 11 countries. This role is dedicated to Zero-X in Valencia.

What you'll work on

- Build parametric 3D models and detailed 2D fabrication drawings for production parts and assemblies.
- Work on design projects for Zero-X: energy plant components, reactor housings, structural elements and industrial enclosures.
- Generate BOMs, assembly instructions and documentation for the workshop floor.




- Collaborate with the engineering team to iterate designs based on manufacturability and cost.
- Manage version-controlled CAD libraries and maintain design standards across projects.

What we're looking for

- Degree in Mechanical Engineering, Industrial Design or a related field (completed or final year).
- Proficient in at least one parametric CAD platform: SolidWorks, Fusion 360, Inventor or Onshape.
- You understand DFM: what makes a part cheap to machine versus expensive.
- A portfolio of CAD work: assemblies, detailed drawings or manufactured parts.

What you get

- Real hardware built from your models — you'll see your parts machined, welded and assembled.
- 10 AM to 5 PM.
- A path into a full-time role across the group for strong performers.
