Join ICOMAT – Revolutionising the Future of Lightweight Manufacturing!
iCOMAT is an advanced manufacturing company that invented Rapid Tow Shearing (RTS) - the only proven technology for producing defect-free curved-fiber composite parts at industrial scale. We deliver the lightest structures possible for aerospace, automotive, defense, and space, at a rate and cost efficiency that far exceeds existing composite production processes.
We build and operate automated factories for composite materials, delivering components to Tier 1 suppliers and OEMs. The business has three main divisions: development of automated production machines, development of software design and production tools, and operation of the factory. We work with 25+ customers and completed the largest ever Series A in composites manufacturing to fuel a significant scale-up, with growth plans that will see the business multiply in size over the next two to three years and expand operations into the UK, Europe and the US.
The business has currently more than 130,000 sqm of production capacity with manufacturing facilities in the UK (Gloucester and Swindon) and the US (Dayton, Ohio); a Hardware R&D Centre in Bristol, UK; and a Software R&D Centre in Athens, Greece.
We are looking for a Proposal Engineer to sit at the critical interface between Business Development, Engineering, and Operations.

Ensure proposals clearly communicate value, differentiation, and delivery approach
Cost modelling & pricing
Build detailed cost models (materials, labour, tooling, overheads)
Work with operations to validate manufacturing assumptions
Support pricing strategy to ensure competitiveness and margin
Cross-functional coordination
Act as the link between BD, engineering, and manufacturing
Drive inputs, timelines, and internal reviews
Ensure alignment between technical solution and commercial offer
Customer engagement
Support technical/commercial discussions with customers
Be able to articulate proposals clearly and confidently
Respond to queries and refine submissions
Continuous improvement
Help standardise proposal templates, costing tools, and processes
Capture learnings from wins/losses to improve future bids
What do we need from you?
Degree-qualified in engineering (materials, mechanical, aerospace, or similar)
1–3 years’ experience in industry (or a strong graduate with relevant exposure)
Background or interest in composites manufacturing
Looking to pivot toward a more commercial, customer-facing role
Enjoys bridging the gap between technical detail and commercial strategy
You’ll likely be someone who:
Is comfortable working across multiple teams and disciplines
Has strong attention to detail, particularly in cost and data
Can communicate clearly, both internally and externally
Wants to grow into a broader commercial or business development role
