Electrolysis Engineer

Rivan Industries (Rivan.com) is a synthetic fuel company designed to decarbonise heavy industry. We’ve developed a unique power-to-fuel machine built for low-capex deployment powered entirely by utility-scale solar. Here’s our entire business plan. We already have individual operating modules of our machine, we’re funded, and we’re now building out the team to bring the vision together and deploy at scale. 

We aim to make synthetic fuel cheaper than fossil fuels and sustain life on earth by keeping the CO2 locked underground. We’re looking for an Electrolysis Engineer that can own our cell performance and longevity over time. If you want to work on a high-impact technology that you’ll see the impact of in the world surrounded by smart people working with a sense of urgency and intensity – this is for you.

The role:

• Optimise current AWE electrolyser design
• Achieve current density targets within cost parameters
• Iterate on membrane, gasket, and electrode designs and material selection for cost, efficiency, and manufacturing simplicity
• Optimise cell and stack design for scaled deployment, with shunt-current and longevity considerations
• Work with mechanical team members to design optimal balance-of-plant
• Rapid ramp-up and ramp-down (linked to DC solar)
• Includes buffer mechanisms and techniques to deliver constant H2 purity and flow
• Offer guidance on control processes
• Design effective testing and safety processes

Core skills:

• 3+ years professional experience
• Bachelor’s or Masters in electrochemical engineering, materials, chemical engineering, or related field
• AWE design, build, and operation experience

The things that are important to us for this role:

• Execution history. What have you built or designed before where you had the responsibility? Project history is key.
• Reasoning by first principles. Can you deconvolute complex scenarios into their foundational truths or parts?
• Urgency. We don’t have time to wait, are you comfortable with a high-degree of risk and pressure to move fast?
• Grit. How relentless will you be despite set-backs? We’re going up against some big opposition.

The things we don’t care about very much:

• Where you went to school / education
• Where you have worked previously

Specifics:

• £70-80K Salary depending on experience
• Significant share options as part of the early team
• In-person work at our HQ in Bermondsey, South-East London
• Flexible time-off

To apply, email why you’re great for this role to [email removed - click apply for more details]. The only thing we’re looking for is execution proof – so any projects you’ve built from the ground up or were responsible for are way more important to us than a CV.

Or, better yet, send your best cell and stack design for a 500kW AWE that achieves 0.5amp/cm^2 at ~2v, with shunt-current considerations on stack length and total voltage, cost no more than £400/m^2.
