Job description

Senior Process Engineer

• Permanent
• Full time
• EC2A1AJ, London, England, United Kingdom

Epoch Biodesign

Epoch Biodesign is a well‑funded, venture‑backed start‑up using biology to make every type of plastic recyclable – starting with Nylon. Using a unique combination of AI, synthetic biology and green chemistry, we are scaling enzymatic recycling processes that transform unrecyclable plastics into new, virgin‑quality materials. These processes yield substantial reductions in carbon emissions and prevent waste from entering landfill or the environment. They also generate disruptive unit economics, allowing us to scale our solutions quickly to solve this urgent challenge.

With our pilot plant already processing Nylon 6,6 waste at the multi‑tonne level, we will imminently complete construction on our larger demo facility. This will produce material that will be used in garments for some of the world’s biggest brands, and also in components for some of the world’s largest car companies.

The Role

We're looking for an experienced and innovative Senior Process Engineer to join the process team. We work in relatively small teams, so there is an opportunity to make a real difference. We’re a positive, driven team who enjoys what we do and is not afraid to roll up our sleeves when it counts, and we're all passionate about sustainability and the environment.

Reporting to the Head of Scale‑Up, you will play a crucial role in developing and scaling up processes for the enzymatic depolymerisation and repolymerisation of polymers.

This is an exciting opportunity to contribute to cutting‑edge solutions that address global sustainability challenges while mentoring the next generation of engineers.

Responsibilities

• Drive Process Innovation: Design and run experiments focused on enzymatic plastic recycling and polymer regeneration.
• Lead Scale‑Up Projects: Manage the transition from lab‑scale R&D to pilot and full‑scale operations, including process design and commissioning.
• Engineer Solutions: Tackle complex technical challenges and deliver high‑impact results across product and process development.
• Mentor & Collaborate: Guide junior engineers and engage with partners, customers, and internal teams to align on goals and outcomes.

Essential Skills and Experience

• Master’s degree in chemical engineering (or related) and Chartered Chemical Engineer status.
• 7+ years in process/product development, with hands‑on expertise in scale‑up, equipment design, and plant commissioning.
• Strong leadership, data analysis, project management, and the ability to clearly communicate complex technical concepts.
• Experience scaling up novel or early‑stage technologies, with a proven ability to translate pilot data into robust demo or commercial operating conditions.
• Strong hands‑on commissioning and troubleshooting skills across complex unit operations (reactors, separations, automation, utilities), ideally in pilot or demonstration environments.
• Ability to work in fast‑paced, innovation‑driven settings, collaborating across R&D, engineering, and operations to rapidly iterate, de‑risk processes, and drive technical improvements.
• Project and Team Management: Ability to independently design, plan, and execute project tasks and scientific R&D. Excellent interpersonal, communication, and organisational skills. Ability to produce and present technical information for internal and external audiences. Experience managing, mentoring, and developing junior engineers.
• A mindset driven by passion for sustainability and a focus on innovation in the recycling, waste, and biotechnology sectors.

Desirables

• A full, clean UK driving licence.

Benefits

Epoch Biodesign offers a comprehensive benefits program. At the moment this includes:

• A generous allowance of 30 days paid holiday (plus the usual 8 bank holidays).
• Meaningful EMI Share Options.
• A non‑contributory pension of 9% employer contribution.
• Optional company covered private medical insurance with Vitality.
• Group Income Protection.
• Group Critical Illness.
• Flexible working around the core times of 10am to 4pm.
• Cycle to work scheme.
• The opportunity to be part of building something remarkable.
