Lead Mechanical Design Engineer; Design Manufacture

Position: Lead Mechanical Design Engineer (Design for Manufacture)
We're looking for a senior mechanical design engineer to turn our anaerobic digestion technology into a product we can manufacture repeatedly and  will be joining our core team to bring our innovation to market, overseeing the deployments of our first brewery systems and building a manufacturing blueprint for every unit that follows. About Future Greens Anaerobic digestion has existed for decades, but conventional systems are too big and expensive to fit next to food and drink factories, making it unfeasible to turn their waste into biogas.

We’ve developed a faster anaerobic digestion process designed to reduce the space needed for on-site waste treatment and biogas production. This enables food factories to cut their waste costs and reduce their reliance on fossil-derived natural gas. We're starting with breweries that have concentrated waste streams and a high gas demand. Once proven here, we plan to scale it across the whole food and drink sector and the wider bioeconomy to help all industries that produce biodegradable byproducts.

We've demonstrated the process in the lab, ran a pilot, applied for a patent and lined up customers for full-scale systems. We are now turning this technology into equipment we can manufacture and deploy repeatedly. The impact of your role You will be joining after our seed round, as we move towards our first commercial deployments. As our Lead Mechanical Design Engineer, you will lead mechanical design from CAD through to deployment, working with fabricators and installation partners responsible for building and installing the systems.

Your role is to ensure the designs are practical to manufacture and assemble, and to resolve engineering issues as they arise. What you will work on Design reactor equipment in CAD, considering materials, fabrication methods and assembly from the outset. Establish design workflows and select the software tools to support them. Build and maintain a bill of materials (BOM) cost model to compare design options against target unit costs.

Assess fabricators and suppliers, source components and qualify manufacturing partners. Oversee fabrication, assembly and installation of the first brewery systems, working with the wider engineering team. Turn deployment feedback into clear, repeatable design specifications. Simplify designs for manufacture at scale, removing unnecessary cost and complexity. What we're looking for You have designed industrial equipment and understand what happens when a design meets the realities of fabrication, assembly and cost.

We want to hear about the decisions you made, the trade-offs involved and what you learned from seeing your equipment get built. Relevant skills and experience include:
Responsibility for mechanical design from initial concept through to build. There is no minimum number of years: what you have designed and delivered matters more. Strong mechanical design and CAD skills. Practical knowledge of materials, fabrication methods and assembly, with a track record of designing for manufacture. Experience building BOM cost models or designing to a cost target. Direct work with fabricators and suppliers, including sourcing and qualification.

An interest in using AI tools to improve engineering workflows. A hands-on approach and the confidence to make and explain engineering decisions as the product develops. Relevant backgrounds include working with tanks, vessels, tankers, skid-mounted process equipment, modular or containerised systems and other fabricated industrial equipment. Experience in a fabrication design office or taking a new product into repeatable production would also be valuable.

We're not looking for an exact path, but the skills and motivation to develop practical…
