Embedded Systems Engineer

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, whilst vertically integrating with off-grid DC solar and the European gas-grid. We’ve recently deployed the UK’s largest synthetic fuel plant and are planning to 1000x this scale in the next 2 years.

To make the cheapest synthetic fuels on earth we need to have our electrical systems efficient, cheap, and scaleable. That means having end-to-end ownership of hardware and software, both in our deployed machines and in our factory, and everything in between. We want to bring everything in-house. To do that we need excellent software and hardware to design/test/deploy thousands of machines as soon as possible. If you want to work at the intersection of electronics, firmware, and software that makes a real difference, we want to meet you.

We are looking for a mid-career engineer who can take ownership of substantial subsystems and help scale embedded systems from prototype to high-volume industrial deployment.
