Senior Process Engineer

Overview

Concrete4

Change (C4C) is a pioneering R&D company developing breakthrough technology to permanently mineralise CO₂ in concrete. We are finalising a mini full-flowsheet pilot plant at our Nottingham facility to operate over the next six months and feed into process design documentation and models for a scalable commercial demonstrator.

Senior Process Engineer (Job title flexible). Location: Nottingham, UK. Type: Permanent, Full-Time. Start Date: Immediate.

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

• Collaborate with the CTO to define, optimise, and execute scale-up plans
• Develop process models and design documents, including heat and mass balances, equipment lists and sizing, utility and waste profiles
• Prepare PFDs, process descriptions, preliminary plot plans, techno-economic evaluations
• Identify opportunities for process improvements and integration of chemical recovery steps

• Pilot & Commercial Plant Operations
• Support commissioning, operation, and troubleshooting of the mini-plant
• Ensure learnings from the pilot feed into the commercial plant design
• Manage experimental runs and ensure high-quality data generation
• Oversee maintenance, upgrades, and modifications of pilot systems
• Forecast engineering workload and resource needs
• Lead or support cross-functional teams including subcontractors and EPCs
• Ensure safety, quality, and documentation standards are met
• Project manage engineering tasks, time, and budgets

• Cross-Disciplinary Collaboration
• Work with chemists, mechanical engineers, process control engineers, and plant operators
• Provide clear communication and lead by example
• Support operational safety through systems like permit-to-work and equipment isolation
• Influence technical direction, team structure, and scale-up strategy

• 10+ years’ experience in process design, commissioning, and scale-up, ideally involving solids handling or mineral processing
• Strong grasp of unit operations and chemical/physical transformations
• Proven ability to manage EPCs, subcontractors, and pilot plant construction
• Experience delivering engineering packages from concept to deployment
• Ability to analyse plant data and implement continuous improvement
• Strong project management and leadership skills
• Experience with Python, Excel, Aspen, Thermoflex, or similar tools
• Exposure to techno-economic analysis and cost modelling
• Knowledge of PLCs, SCADA, electrical systems, and process control
• Fluent in more than one language
• Forklift licence (or willingness to obtain one)
• Experience in carbon capture and mineralisation processes
• Background in concrete or cement chemistry
• Educated to at least BEng/BSc in Process or Chemical Engineering
• Willingness to travel and potentially relocate (future plant expected in UK or EU)
• Bonus scheme tied to key milestones
• Private health insurance & pension plan
• Generous holiday entitlement
• Free food and coffee at the office
• Equity participation opportunities
• Work alongside world-class partners and technology leaders
• Full exposure to a scale-up journey from pilot to full commercialisation
• Unrivalled long-term career progression in climate tech
