Job Description
Rivan Industries (Rivan.com) is a synthetic fuel company designed to decarbonise heavy industry. We aim to make synthetic fuel cheaper than fossil fuels and sustain life on earth by keeping the CO2 locked underground.
We’ve design and manufacture modular synthetic fuel plants consisting of a DAC system, an Alkaline Electrolyser, and a Sabatier Reactor, vertically integrating with off-grid DC solar and the European gas-grid. Here’s our entire business plan. We’ve recently deployed the UK’s largest synthetic fuel plant and are planning to 1000x this scale in the next 2 years.
We have one single goal – reduce the leveralised cost of methane to the point drilling stops and companies mine the sky for carbon. If you urge to make a difference in the real-world, surrounded by people you admire doing great work with intensity, this is for you.
The role:
- Develop and refine process models for Rivan’s lime-based Direct Air Capture (DAC) process, integrating thermodynamics, kinetics, and transport phenomena
- Perform first-principles heat and mass transfer calculations, dynamic process simulations, and optimisation studies.
- Work cross-functionally with experimental and design teams to validate models against empirical data, refine process understanding, and inform plant operation and scale-up.
- Build and maintain modular simulation tools (e.g. MATLAB, Aspen Plus, COMSOL, or custom Python models) to support techno-economic and performance assessments.
Core skills:
- 3–7 years experience in process modelling, computational science, or chemical/process engineering R&D.
- Bachelor’s/Master’s in Chemical Engineering, Process Systems Engineering or related field (PhD advantageous).
- Proven experience with MATLAB, Aspen Plus/HYSYS, and/or COMSOL, ANSYS Fluent, or Python-based CFD.
- Strong background in heat and mass transfer, reaction engineering, and first-principles modelling (PDEs, reaction kinetics, etc.).
- Experience in model validation with lab or pilot data; understanding of solid–gas systems (calcination, hydration, carbonation); and past-demonstration of system optimisation preferred.
The things we don’t care about very much:
- Where you went to school / education.
- Where you have worked previously.
Specifics:
- £60K Salary depending on experience.
- Significant share options as part of the early team.
- In-person work at our HQ in Bermondsey, South-East London.
- Extensive relocation support, including £6000 per year extra to live close to our HQ.
- Unlimited time-off.
