Lead process design, scale-up, and project delivery across Cocoon’s next-generation slag activation system. Work closely with process and mechanical engineers, material scientists, researchers, and technicians to optimise our core process and integrate it with existing steelmaking infrastructure. This role spans front-end engineering, pilot and lab development, capital project delivery, and commissioning. You’ll take ownership of process design packages, champion process safety, and represent process engineering internally and externally as we scale from pilot to demonstration, and to commercial scale.
Job Responsibility:
Own and deliver process design packages (PFDs, mass and energy balances, equipment specifications) across front-end engineering, detailed design, and execution phases
Produce and review process models and calculations
Plan, execute, and analyse lab and pilot-scale development trials to de-risk process scale-up
Lead process engineering input across the project lifecycle, from design through installation and commissioning
Ensure alignment of process design with cost, schedule, operability, and performance targets
Lead and support process safety reviews (e.g. HAZID, HAZOP) and proactively manage process risks
Ensure designs meet internal, regulatory, environmental, and safety requirements
Represent process engineering in discussions with equipment vendors, consultants, trial partners, and contractors
Clearly define and manage technical scope and requirements with third parties
Champion sustainable design, energy efficiency, and continuous improvement in process and equipment selection
Provide technical leadership and mentorship to engineers and technicians
Support the development of fellow engineers and contribute to a collaborative, inclusive, knowledge-sharing culture
Contribute to continuous improvement in design practices, safety performance, and project outcomes
Support installation, commissioning, and testing activities in the UK and internationally
Requirements:
Master’s degree in Chemical or Process Engineering
5+ years of industry experience in process development and scale-up
Strong technical foundation in process design, modelling, engineering calculations, and process safety
Comfortable owning deliverables in lean project teams without heavy functional support
Thrive in fast-paced, evolving environments
Practical, hands-on problem-solving mindset
Communicate clearly and confidently across technical and non-technical audiences
Nice to have:
Hands-on experience across the capital project lifecycle, including design, construction, commissioning, and operations
Experience scaling technologies from lab or pilot to demonstration or full-scale implementation (TRL 4/5 to TRL 8/9)
Familiarity with stage-gate development processes and capital project lifecycles
Knowledge of minerals processing, solids handling equipment, or industrial water systems
Background in steelmaking, pyrometallurgy, or high-temperature fluid/refractory systems, including FMEA or structured risk methodologies
