Senior Mechanical Engineer + Equity at Rivan Industries

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.

• Your job is the full ownership of a major hardware module (Reactor, Electrolyser, or DAC) with the freedom to challenge every design assumption and manufacturing step.
• You will 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.

• Lead concept generation, architecting, and technical requirements capture for next‑generation synthetic fuel plant modules using Solid Works.
• 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.

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

Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
