Senior Process Engineer

• Location: Equisera’s purpose-built innovation campus in the beautiful Gloucestershire countryside.
• Contract Type: Full-time

At Equisera, you'll help build one of the world's first commercially deployable carbon-negative energy technologies, tackling some of the hardest engineering challenges in the global energy transition.

Our breakthrough RiPR (Rising Pressure Reformer) process converts wet biogenic feedstocks, including agricultural and food waste and even plastics, into high-yield hydrogen and biomethane with minimal pre-processing. The process simultaneously captures carbon dioxide and produces biochar, delivering a truly carbon-negative energy solution.

Backed by significant private investment, government innovation funding and strategic industry partnerships, you will be joining us at a pivotal stage as we deliver our first commercial-scale plant. You'll join a small, passionate, high-impact team helping shape the future of carbon-negative energy.

The Role

Reporting to the Chief Engineer, you will lead Equisera's multidisciplinary engineering design team. You will define how RiPR is engineered into safe, operable and commercially viable process plants while leading concept development, detailed design, procurement, commissioning and continuous improvement.

Why this role is different

Unlike many engineering roles, this is not a desk-bound design position. At our purpose-built innovation campus, engineering, laboratories and manufacturing sit under one roof, giving you the opportunity to take ideas from first principles through laboratory validation, pilot plant and ultimately commercial deployment.

Key Responsibilities

You will develop the process engineering systems that underpin RiPR as it progresses from research and development to commercial deployment.

You will oversee chemical and mechanical engineers to define process requirements; support equipment selection; ensure that decisions are supported by robust analysis and sound engineering judgement and develop integrated process plant designs that are safe, practical and cost-effective to build and operate.

The role will involve leading the design efforts, reviewing and approving designs, supplier engagement, procurement, commissioning activities and operational troubleshooting, and mentoring the junior members of the team. You will contribute to the continuous improvement of RiPR, engineering processes and standards as the business grows.

You will own the process engineering Basis of Design, leading the development of Front End Engineering Design (FEED) packages that underpin the safe, efficient and commercially successful deployment of RiPR.
