Senior Process Engineer

Overview Concrete4Change (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.Position Senior Process Engineer (Job title flexible). Location: Nottingham, UK. Type: Permanent, Full-Time. Start Date: Immediate.The Opportunity 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.Key Responsibilities Process Design & Scale-upCollaborate with the CTO to define, optimise, and execute scale-up plansDevelop process models and design documents, including heat and mass balances, equipment lists and sizing, utility and waste profilesPrepare PFDs, process descriptions, preliminary plot plans, techno-economic evaluationsIdentify opportunities for process improvements and integration of chemical recovery stepsPilot & Commercial Plant OperationsSupport commissioning, operation, and troubleshooting of the mini-plantEnsure learnings from the pilot feed into the commercial plant designManage experimental runs and ensure high-quality data generationOversee maintenance, upgrades, and modifications of pilot systemsForecast engineering workload and resource needsLead or support cross-functional teams including subcontractors and EPCsEnsure safety, quality, and documentation standards are metProject manage engineering tasks, time, and budgetsCross-Disciplinary CollaborationWork with chemists, mechanical engineers, process control engineers, and plant operatorsProvide clear communication and lead by exampleSupport operational safety through systems like permit-to-work and equipment isolationInfluence technical direction, team structure, and scale-up strategyQualifications & Experience 10+ years\’ experience in process design, commissioning, and scale-up, ideally involving solids handling or mineral processingStrong grasp of unit operations and chemical/physical transformationsProven ability to manage EPCs, subcontractors, and pilot plant constructionExperience delivering engineering packages from concept to deploymentAbility to analyse plant data and implement continuous improvementStrong project management and leadership skillsExperience with Python, Excel, Aspen, Thermoflex, or similar toolsExposure to techno-economic analysis and cost modellingKnowledge of PLCs, SCADA, electrical systems, and process controlFluent in more than one languageForklift licence (or willingness to obtain one)Experience in carbon capture and mineralisation processesBackground in concrete or cement chemistryEducated to at least BEng/BSc in Process or Chemical EngineeringWillingness to travel and potentially relocate (future plant expected in UK or EU)Bonus scheme tied to key milestonesPrivate health insurance & pension planGenerous holiday entitlementFree food and coffee at the officeEquity participation opportunitiesWork alongside world-class partners and technology leadersFull exposure to a scale-up journey from pilot to full commercialisationUnrivalled long-term career progression in climate techSeniority DirectorEmployment type Full-timeJob function Manufacturing, Product Management, and ProductionIndustries: Chemical Manufacturing and Chemical Raw Materials ManufacturingNote: This description excludes boilerplate and unrelated postings to focus on the role and requirements.
