Key Responsibilities

  • Use Onshape to create fast, functional 3D CAD models and assemblies

  • Translate rough concepts into usable geometry ready for early-stage prototyping

  • Collaborate across sectors (space, aerospace, medtech, transport, IoT, and more)

  • Respond quickly to design feedback and iterate efficiently

  • Keep CAD structures clean, version-controlled, and shareable

Required Skills

  • Proficient in Onshape (non-negotiable)

  • Strong spatial reasoning and mechanical intuition

  • Basic render or visualisation skills (for communicating concepts clearly)

  • Prioritise testability and momentum over visual perfection

  • Enthusiastic about working on real-world, cross-sector hardware

  • UK citizen or UK permanent resident (required for defence-related projects)

Nice to Have

  • Hands-on experience with 3D printing, laser cutting, CNC, or similar

  • Startup, hackathon, or early prototyping experience

  • Understanding of Design for Manufacturability (DfM), tolerances, or basic simulation tools

  • SimScale proficiency within Onshape (desired, not required)

Tools & Setup

  • Bring your own computer (any modern, web-accessible machine is fine)

  • We provide all necessary licenses: Onshape, Microsoft Office, and others as needed

  • Remote first, with optional hybrid work available from our Leicester, UK office

Compensation

  • £500 per month retainer, paid on the last day of each calendar month

  • Must be paid in GBP into a UK GBP bank account (mobile and challenger banks are accepted)

  • Expected workload: approximately 20 hours per month

  • Equivalent to £25 per hour, structured to remain tax-free under the UK personal allowance

  • This is a freelance contract. The freelancer is responsible for managing their own income tax via self-assessment

  • Compensation and hours may be increased based on performance

  • Flexible hours and deliverables

  • Bonus opportunities for major contributions

  • 45-minute interview including:

  • 15-minute informal chat (get to know each other)

  • 30-minute live RapidCAD session (random product introduced at the start)
