Job description

An innovative engineering organisation operating within the marine and defence sectors is seeking a Composites Engineer to join its R&D team. This is a hands-on, technical role with exposure to testing, research, and collaboration with external partners. The role offers significant growth potential as the company continues to expand its in-house capabilities.


Role Overview

As a Composites Engineer, you will play a key role in advancing the company’s materials science and processing capabilities, with a primary focus on polymer composites. Your work will be split approximately as follows:

  • Testing (1/3): Hands-on operation, setup, and execution of materials and component tests
  • Research (1/3): Supporting materials development projects and generating technical solutions to advance product performance
  • Third-party liaison (1/3): Identifying and managing external test houses, suppliers, and research partners to complement in-house capabilities


You will have the opportunity to influence future product and manufacturing strategies, and develop into a subject matter expert, with a clear path for progression as the company continues to bring more activities in-house.


Key Responsibilities

  • Lead and support composite materials testing, both in-house and in collaboration with external test facilities
  • Conduct applied research on polymer composites to support new product development
  • Identify and liaise with external test houses, suppliers, and research partners, ensuring successful third-party testing and research outcomes
  • Operate, maintain, and optimise laboratory and test equipment
  • Collaborate effectively within the team, contributing to planning, goal setting, and project delivery
  • Communicate clearly with internal teams and external partners
  • Undertake occasional domestic travel as required


Candidate Requirements

  • Bachelor’s degree (or equivalent) in Mechanical Engineering, Materials Science, or a related discipline
  • Proven experience working with polymer composites
  • Experience with metallurgy and ceramics is desirable but not essential
  • Previous exposure to materials testing, research projects, or working with external partners is advantageous
  • Hands-on experience with laboratory or test equipment is desirable; in-house training will be provided
  • Strong organisational, teamwork, and communication skills
  • Motivated, self-starting, and results-oriented approach


What’s on Offer

  • A technically challenging, hands-on R&D role focused on composites
  • Exposure to both in-house and third-party testing and research
  • Opportunity to develop into a subject matter expert with a clear progression path
  • Collaborative team environment within a forward-looking engineering company
  • Chance to influence product and manufacturing strategies and contribute to sustainable, high-performance solutions
