Job Description

I’m hiring on behalf of a pioneering clean-energy technology company, supporting them in securing an experienced Senior Mechanical Design Engineer for a 3-month paternity cover contract. This role sits within their R&D function and focuses on mechanical design for next-generation electrochemical hardware.

If you're motivated by meaningful engineering challenges and want to contribute to a mission-led organisation aiming to change the future of green energy, this is a great short-term opportunity.

The Opportunity

You’ll work closely with the technical leadership team on key mechanical componentry for their novel electrolyser system. Expect high-impact work, rapid iteration, and the chance to influence designs at an early, innovative stage.

What You’ll Be Doing

Producing detailed CAD designs and drawings (OnShape preferred; SolidWorks acceptable).

Delivering fully-specified drawings, BoMs, and design data for manufacturing and procurement.

Identifying design and process improvements across mechanical components and assemblies.

Providing technical leadership or support on product development and improvement projects, including working with external suppliers.

Applying rapid-iteration principles: fast prototyping, fail-fast learning cycles.

Contributing to design and safety reviews (FMEA, HAZOP).

Collaborating closely with electrochemical, process, safety, and electrical engineering teams.

Managing component suppliers and expediting critical parts when needed.

About You (Essential)

Degree (BEng or equivalent) in Mechanical Engineering.

4+ years’ experience in mechanical design engineering, including component design for high-volume manufacture.

Strong CAD capability and experience producing engineering drawings to BS8888 standards.

Experience participating in safety methodologies (e.g., HAZOP, FMEA).

Self-starter, able to operate effectively in a fast-paced, innovative environment.

Strong organisational skills and attention to detail.

Comfortable managing multiple workstreams simultaneously.

Desirable Experience

Knowledge of hydrogen systems, electrolysers or fuel cells.

Familiarity with high-pressure equipment design (ASME VIII div 3, PD5500, EN 13445).

Experience with corrosive service materials selection.

Background in early-stage product development and moving designs toward commercialisation.

Exposure to supercritical water reactor technology
