Are you a senior Process Engineer looking to take full ownership of scaling a breakthrough chemical technology from pilot through to commercial readiness?

This is a rare opportunity to step into a principal-level leadership role within a fast-growing, venture-backed climate tech company developing innovative chemical recycling processes to recover high-value carbon fibre for reuse across aerospace, defence, and industrial sectors.

Following significant recent funding, the company is entering a critical phase - commissioning its first pilot-scale processing line in Bristol. You will take ownership of the engineering programme, leading scale-up from process development unit through to full pilot operation and beyond.

The Role

• Lead pilot plant build, commissioning, and ongoing process development
• Own scale-up strategy, engineering deliverables, and core process documentation (PFDs, P&IDs, balances)
• Translate lab chemistry into safe, reliable pilot-scale operations (including HAZOP & DSEAR ownership)
• Drive process performance, continuous improvement, and lead/develop the engineering team in line with technical strategy

The Person

• Chartered Engineer (CEng) or working toward it (IChemE, IMechE or similar)
• Significant experience in process engineering within industrial environments (chemicals, materials, or similar)
• Strong process design capability (P&IDs, PFDs, mass & energy balances)
• Experience across scale-up stages (lab – pilot – industrial)
• HAZOP leadership experience (chairing or co-chairing)

We are an equal opportunities company and welcome applications from all suitable candidates.
