Principle Mechanical Engineer
A pioneering climate technology company is developing innovative algae cultivation systems to enable the production of sustainable low-carbon fuels and chemicals at a commercial scale. Their technology combines advanced materials, industrial manufacturing processes, and engineering solutions to support the transition towards cleaner energy.
This is an exciting opportunity for a Mechanical Engineer to take ownership of the development of large-scale polymer cultivation systems, helping to move designs from prototype through to commercial production. You will work closely with manufacturing partners, suppliers, and multidisciplinary engineering teams to optimise product design, manufacturing processes, and deployment of the technology globally.
Key Responsibilities - Principle Mechanical Engineer
- Lead the mechanical development of large-scale polymer cultivation tanks, taking designs from prototype stage through to commercial manufacture.
- Develop and optimise manufacturing processes for welded thin-film polymer structures and flexible materials.
- Collaborate directly with international manufacturing partners to improve production methods, product quality, and cost efficiency.
- Support supplier selection, factory trials, production ramp-up, and the transition into high-volume manufacturing.
- Design and develop supporting mechanical systems, including fluid handling equipment, pumps, valves, manifolds, and pipework.
- Produce manufacturing specifications, quality control procedures, and acceptance criteria to ensure consistent product performance.
- Perform engineering analysis and calculations relating to structural performance, stresses, and pressure loading.
- Support prototype builds, testing activities, commercial deployments, and integration with wider mechanical and automation systems.
