R&D Mechanical Engineer

A pioneering clean energy technology company is developing advanced electrochemical hardware to support the transition towards more sustainable energy systems. Following recent growth and investment, the business is expanding its engineering capability as it develops its technology from early-stage R&D towards a scalable commercial product.

This is an exciting opportunity for a Mechanical Engineer to take a key role in the development of novel physical hardware. You will work from first principles to develop new concepts, understand the physics behind them, build and test prototypes, and rapidly improve designs based on real-world results. This is a highly hands-on R&D role suited to someone who enjoys creating new technology rather than making incremental changes to established products.

Key Responsibilities – R&D Mechanical Engineer

  • Develop innovative mechanical components and hardware from early-stage concepts through to working prototypes.
  • Use first-principles engineering to understand how stress, fluids, pressure, materials, thermal behaviour and other physical factors influence designs.
  • Translate technical requirements and R&D findings into practical mechanical concepts and components.
  • Use engineering calculations, FEA, CFD and other analytical methods where appropriate to guide design decisions.
  • Develop CAD models and mechanical designs to communicate and progress engineering concepts.
  • Build, assemble and test prototypes to quickly validate new ideas and identify areas for improvement.
  • Work through rapid design-build-test-learn cycles, using failures and test results to continuously improve designs.
  • Develop test rigs, fixtures and experimental setups to understand component and prototype performance.
  • Analyse test results and translate findings into practical design changes.
  • Work closely with scientists, engineers, technicians and manufacturing partners to develop new hardware.
  • Support material selection, mechanical testing, failure investigations and root-cause analysis.
  • Contribute to the development of a fast, practical and evidence-led hardware development culture.

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

Start with a chat, not a search bar

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.

Experience & Skills – R&D Mechanical Engineer

  • MEng or equivalent advanced qualification in Mechanical Engineering or a closely related engineering discipline.
  • Approximately 5+ years' experience developing physical products or hardware within an R&D, product development or innovation environment.
  • Strong first-principles understanding of mechanical engineering, including areas such as stress, structures, fluids, pressure, materials and thermal behaviour.
  • Proven experience designing individual mechanical components or hardware rather than primarily integrating existing systems or equipment.
  • Experience developing genuinely new products, technologies or concepts rather than solely making incremental changes to established products.
  • Strong understanding of how mechanical design decisions influence the performance of a wider product or system.
  • Comfortable using CAD to develop and communicate mechanical concepts.
  • Experience with FEA, CFD, multiphysics modelling or similar analytical methods, either directly or through working effectively with specialist engineers.
  • Strong hands-on engineering experience, including building, assembling and testing prototypes.
  • Experience taking designs through rapid concept, prototype, test and iteration cycles.
  • Able to make sensible engineering decisions from incomplete information using calculations, experimentation and engineering judgement.
  • Comfortable operating within a fast-paced R&D or startup environment where requirements and designs evolve quickly.
  • Strong problem-solving skills with a practical approach to investigating failures and developing solutions.
  • Able to collaborate effectively with multidisciplinary engineers, scientists, technicians and external suppliers.
