Job Description:

PRINCIPAL DESIGN ENGINEER — MOULDED COMPOSITES

Permanent | Eynsham, Oxfordshire

THE BUSINESS

This is a precision engineering business at a genuinely exciting point in its development. Backed by significant private equity investment, they’re growing fast across aerospace, defence and motorsport, developing some of the most demanding composite and metallic components in the industry. The engineering team is expanding, the order book is strong, and the work is technically serious.

This is a Principal-level hire. The brief is straightforward: they want one of the best moulded composites design engineers in the country.

THE ROLE

You’ll be the technical authority on complex composite and metallic product design, leading from concept through to production on programmes that push the boundaries of what’s achievable in moulded composites. This isn’t a role for someone who wants to execute someone else’s vision. You’ll be setting the technical direction, mentoring the design team, and influencing how the engineering function develops.

Day-to-day you’ll be:

  • Leading design and development of new composite and metallic products from concept to industrialisation
  • Acting as the senior technical voice on assigned programmes, design reviews, feasibility, root cause, the lot
  • Working closely with NPI, Manufacturing Engineering and Quality to get designs production-ready
  • Driving technology development, contributing to IP and helping shape where the business goes next
  • Mentoring and elevating the design engineers around you

WHAT WE’RE LOOKING FOR

The non-negotiables:

  • Deep moulded composites design experience, CFRP, prepreg, RTM or similar
  • Siemens NX proficiency and Teamcenter PLM
  • Proven ability to take complex products from concept through to manufacture
  • Background in aerospace, defence, motorsport or F1, somewhere the bar is high

What sets the right person apart is a combination of genuine technical depth and the confidence to lead. You know why a design decision is right, you can defend it, and you can bring people with you.

THE SETUP

  • Principal Engineer level – title and package to match
  • Permanent role
  • Eynsham, Oxfordshire (on-site)
  • A business where engineers have real influence
