You will lead the development of high-fidelity process models to optimize a vertically integrated synthetic fuel system. By building simulations of Direct Air Capture and Sabatier reactors, you will act as the "puppet master" directing physical resources and identifying performance ceilings before they impact the 1000x scale-up mission.

Computational Scientist at Rivan Industries
Join the team that recently deployed the UK’s largest synthetic fuel plant and is now scaling 1000x to make fossil fuels obsolete. As a Computational Scientist, you will be the 'puppet master' of the physical world, using bits to move atoms by building the simulation infrastructure that underpins a generation-defining climate product. If you have 3-7 years of experience in process modelling and want to work at the intersection of Direct Air Capture and green hydrogen, this Bermondsey-based role offers a £70k-£80k salary plus a unique £6k annual housing subsidy to live near HQ.
