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 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 are looking for someone to build and own the models that determine what we design, build, and scale. You will develop first‑principles and data‑driven models of our lime‑based DAC system and use them to make real engineering decisions. This is not a pure modelling role. Your work will directly influence hardware, operat...
