Senior Process Engineer

We are seeking a Senior Process Engineer to lead our scale-up journey—from lab pilot to commercial demonstration. Reporting to the CTO, you will play a key role in process modelling, pilot operation, scale-up design, equipment selection, and coordination with EPCs, subcontractors, and internal teams.

• Support operational safety through systems like permit-to-work and equipment isolation
• Identify opportunities for process improvements and integration of chemical recovery steps
• Collaborate with the CTO to define, optimise, and execute scale-up plans
• Influence technical direction, team structure, and scale-up strategy
• Provide clear communication and lead by example
• Oversee maintenance, upgrades, and modifications of pilot systems
• Work with chemists, mechanical engineers, process control engineers, and plant operators
• Ensure learnings from the pilot feed into the commercial plant design
• Support commissioning, operation, and troubleshooting of the mini-plant
• Ensure safety, quality, and documentation standards are met
• Manage experimental runs and ensure high-quality data generation
• Forecast engineering workload and resource needs
• Work alongside world-class partners and technology leaders
• Project manage engineering tasks, time, and budgets
• Develop process models and design documents, including:
• Lead or support cross-functional teams including subcontractors and EPCs

This is an exciting opportunity to apply multidisciplinary engineering skills to a truly transformative climate technology.

• 10+ years’ experience in process design, commissioning, and scale-up, ideally involving solids handling or mineral processing
• PFDs, process descriptions, preliminary plot plans
• Experience with Python, Excel, Aspen, Thermoflex, or similar tools
• Fluent in more than one language
• Strong project management and leadership skills
• Exposure to techno-economic analysis and cost modelling
• Experience delivering engineering packages from concept to deployment
• Educated to at least BEng/BSc in Process or Chemical Engineering
• Experience in carbon capture and mineralisation processes

• Knowledge of PLCs, SCADA, electrical systems, and process control
• Forklift licence (or willingness to obtain one)
• Ability to analyse plant data and implement continuous improvement
• Background in concrete or cement chemistry
• Strong grasp of unit operations and chemical/physical transformations
• Willingness to travel and potentially relocate (future plant expected in UK or EU)
