Job description

Rivan Industries is a synthetic fuel company decarbonising heavy industry. We’re making synthetic fuel cheaper than fossil fuels, sustaining life on Earth by keeping the CO2 locked underground.

There is no boilerplate engineering in this system; only the most innovative, problem-solving engineers can thrive on this challenge. We practice our culture, working in small teams, expecting complete ownership and ground-up reasoning from our engineers, whilst executing at speed.

We operate with minimal process and bureaucracy, only what is essential to ensure our systems are safe, legally compliant, and deployed on time; everything else is up to you.

The role: Own process engineering of Rivan’s DAC system

The role encompasses the full development cycle, but can be tailored to the specialist skillset of the applicant. We need you to:

• Ideate novel architectures and system integrations for a solid phase, cyclic lime-based DAC process
• Run bench-scale testing and analysis of calcination, hydration, carbonation and sorbent cyclic stability
• Own detailed design and optimisation of unit operations across the full CaCO₃ -> CaO -> Ca(OH)₂ -> CaCO₃ loop
• Tightly integrate the DAC module with our methanation and electrolysis units
• Design intelligent, inherently safe, high-temperature, steam-rich, solids-handling systems
• Specification and procurement of equipment
• Own the assembly, integration, site commissioning and testing of our system

Essential skills:

• 5+ years of professional experience.
• Bachelor’s or Master’s degree in Chemical Engineering or a related field.
• Experience designing and building plants with solid-handling
• Experience with high-temperature processes such as calcination, pyrolysis, reforming, roasting or thermal treatment.
• Experience working with powders/granular materials

Additional skills:

• HAZID, HAZOP and LOPA leadership experience
• CAD experience
• Chartered Engineering Status

Specifics:

• £70-100k salary depending on experience
• Significant share options as part of the early team
• In-person work at our HQ in South Bermondsey, South London – flexibility considered based on personal circumstances
• Extensive relocation support, including £6000 per year extra to live near our HQ
• Private health insurance
• Unlimited time-off

We encourage exceptional applicants from all backgrounds to apply for this role, even if they do not meet all the requirements listed.
