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. Good to know: this is an unpaid, fully on-site internship in Valencia, Spain. No remote or hybrid option. Apply below with your CV and portfolio.
