Job Title

Senior Mechanical Engineer

Salary

£70k-90k + Equity

Company Description

Rivan Industries – Decarbonising heavy industry through synthetic fuels

Job Description

You will own the end-to-end design and manufacture of a critical Rivan sub-system, such as a reactor or electrolyser. This role involves rethinking conventional high-cost hardware from first principles to enable mass manufacturing. You'll drive everything from initial concept and CAD modeling to hands‑on workshop fabrication, testing, and vendor management.

Location

London, UK

Why this role is remarkable

  • Full ownership of a major hardware module (Reactor, Electrolyser, or DAC) with the freedom to challenge every design assumption and manufacturing step.
  • Join an elite seed‑stage team of ~20 engineers from Imperial, Cambridge, and high‑performance backgrounds like rocketry and motorsports.
  • Exceptional relocation and local living support, including an extra £6,000 per year specifically to help you live close to the Bermondsey HQ.

What you will do

  • Lead concept generation, architecting, and technical requirements capture for next‑generation synthetic fuel plant modules using SolidWorks.
  • Design and commission bespoke test rigs to rapidly validate underlying thermofluid hypotheses and iterate on hardware performance.
  • Manage the entire production lifecycle, from generating fabrication drawings to hands‑on assembly and integration within the onsite workshop.

The ideal candidate

  • 5+ years of professional experience in mechanical or aerospace engineering with a proven track record of designing and building complex systems.
  • Advanced competency in first‑principles engineering, including thermofluids (heat/mass transfer), FEA, CFD, and analytical modeling using Python.
  • Extensive hands‑on workshop experience with a DFM/DFA mindset, capable of bridging the gap between digital CAD design and physical hardware fabrication.
