Project Engineer, Non-Metallics
Polymer and Composite Services/Materials Performance and Integrity
Location: Cambridge, Granta Park
Contract: Permanent
Hours: Full time, 36 hours per week
Job Profile: Engineer
Salary/annum: Up to £50,000 per annum
Reference number: JR100819
Closing Date: 04 September 2026
Description of role:
The Polymer and Composites Services Section within the Materials Performance and Integrity Technology Group is expanding due to order growth and the increasing use of non-metallic materials in established and emerging industrial applications. Over recent years, the team has delivered significant and sustained growth and is seeking a talented Project Engineer to join this fast-moving technical environment, helping to underpin technical excellence and support an expanding market share.
The successful candidate will work across the non-metallic materials portfolio, supporting technical delivery in coatings, polymers and composites. This will include involvement in applied research, industrial consultancy, materials testing, characterisation, failure assessment, technology development and client-facing project work. The role will suit a materials engineer, polymer engineer, surface engineer, composite engineer or mechanical engineer with strong technical foundations and the ability to work across more than one non-metallics discipline.
The successful candidate will strengthen the core skills of an exciting and innovative team by taking on responsibilities including project management, preparation and negotiation of contract proposals, laboratory experiments, testing and characterisation activities, data interpretation, and preparation of high-quality technical reports. Similar responsibilities are reflected across the existing polymer, composite and coating advert examples.
The work may involve polymeric materials, reinforced thermoplastics, composite structures, composite pipes and connectors, coating systems, surface characterisation, physical and mechanical testing, environmental performance, degradation and failure investigation. The successful candidate does not need to be an expert in all these areas from day one but should have strong technical capability in at least one relevant area and the motivation to develop broader expertise across coatings, polymers and composites.
Applicants must possess good team and networking abilities, demonstrate initiative and self-motivation, and have strong verbal and written communication skills. Applications are welcomed from candidates with a strong technical background and a good degree in materials science, polymer science, polymer engineering, composite engineering, chemistry, surface engineering, mechanical engineering, aerospace engineering or a related discipline. Similar qualification routes are used in the example adverts for polymer, composite and coating roles.
This position may require travel within the UK and abroad depending on project and business needs. The coating advert also notes that some projects may require security-related arrangements depending on the project need.
Main duties and responsibilities:
- Planning and conducting experiments, trials and test programmes to suit customer and project requirements.
- Developing appropriate testing, characterisation and evaluation methods for polymers, coatings and composite materials.
- Supporting work on composite materials and structures, including composite pipes, connectors, manufacturing, testing, mechanical performance and failure assessment.
- Supporting work on coatings and surface technologies, including coating application, surface characterisation, physical testing and performance assessment.
- Applying polymer science and engineering knowledge to the testing, characterisation and evaluation of polymeric and reinforced thermoplastic materials.
- Delivering technical projects efficiently to meet client, health, safety, quality, scope, schedule and budget requirements.
- Preparing technical reports, proposals, presentations and recommendations for industrial clients and internal stakeholders.
- Supporting commercialisation and proposal development efforts by working with project leaders, customers and suppliers.
- Working with the wider team to understand and develop business opportunities for internally developed technologies and services.
- Responding to enquiries from TWI Industrial Members and contributing to the development, negotiation and management of client projects.
- Building effective working relationships with clients, suppliers, universities, research institutes and internal technical teams.
- Contributing to continuous improvement of technical capability, laboratory methods, project delivery and knowledge sharing within the non-metallics area.
