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 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. 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 scalable. 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 senior engineer who can architect, ship, and scale embedded systems that move from prototype to thousands of deployed industrial machines.

The role:

• System architecture design that scales


• Requirements capture, risk analysis, and design reviews


• Firmware design/test/deploy (embedded C/C++, RTOS, embedded Linux)


• Wiring harness design for data and power distribution


• DfMA, DfT


• Integrating the end product with production tools, supply chain, and procurement systems


• Hardware and software test and deployment (factory acceptance rigs, fleet management integrations)

Core skills:

• Embedded-C/C++, RTOS


• Embedded Linux, Yocto project


• CI/CD, Git, automated testing


• Industrial communications standards: Modbus (RTU/TCP), CAN bus, OPC UA, TCP/IP, RS-485


• Hands‑on building experience, fault‑finding and repair


• Experience with functional safety standards (IEC 61508 or related standards)

Preferred skills:

• Regulator compliance (LVD, Machinery Directive, CE/UKCA)


• IEC 61131‑3 (ST/LD/FBD)


• Python 3


• Fleet management


• Solidworks Electrical / ECAD

Specifics:

• £80 - 100k salary depending on experience


• Significant share options as part of the early team


• In‑person work at our HQ in Bermondsey, South London – flexibility considered based on personal circumstances


• Extensive relocation support, including £6,000 per year extra to live close to our HQ


• Private health insurance


• Unlimited time off
