Job description

Principal Process Engineer – Synthetic Fuels

An innovative UK clean technology company developing modular synthetic fuel plants, is looking for a Principal Process Engineer to join its engineering team in South London, on a permanent basis.

The ideal candidate will have 10+ years of process engineering experience, with a strong track record designing, building and commissioning process plants and the ability to take ownership of complex, first-of-a-kind systems from concept through deployment.

The key skills required for the Principal Process Engineer:

• 10+ years of experience in process engineering and process plant design
• Proven experience taking process systems from concept through construction and commissioning
• Strong process safety experience, including HAZOP, FMEA and hazard assessments
• Expertise in P&ID design, process simulation, mass and energy balances
• Experience designing and commissioning large-scale or multi-megawatt process plants
• Strong understanding of complex process systems and process architecture
• Experience working with reactors, electrolysers, DAC or related industrial technologies is highly desirable
• Ability to make engineering decisions for first-of-a-kind technologies and rapidly scaling systems
• Hands-on approach with strong ownership and problem-solving skills
• Comfortable working in a fast-paced, engineering-led environment

You will own process engineering across Rivan's reactor, electrolyser and Direct Air Capture systems, leading process safety and system design from early architecture through to deployment and commissioning. This is an opportunity to join an engineering-first company at an early stage of scaling a novel synthetic fuel technology from MW-scale deployment towards 50MW+ systems.
