We’re looking for a Process Engineer to support process design, development trials, and early-stage scale-up of Cocoon’s next-generation slag activation system. You’ll work closely with process and mechanical engineers, material scientists, researchers, and technicians across lab, pilot, and plant environments. This is an early-career, hands-on role with strong exposure to real-world engineering — from preparing design documentation and running development trials, to supporting equipment installation, commissioning, and process safety activities. You’ll build your technical capability while contributing directly to Cocoon’s scale-up journey.
Job Responsibility:
Participate in process hazard reviews and assist in identifying and mitigating process safety risks
Maintain a safety-first mindset in all engineering activities and promote a proactive safety culture
Prepare and update engineering documents, including PFDs, P&IDs, mass and energy balances, and equipment specifications
Support process calculations and design work under guidance from senior engineers
Organise and run lab and pilot-scale development trials with cross-functional teams
Gather, analyse, and interpret data to support process understanding and scale-up decisions
Support design coordination, installation, and commissioning of new equipment and processes
Build knowledge of standard process engineering deliverables, tools, and methodologies through hands-on work and mentorship
Liaise with equipment suppliers, contractors, and internal stakeholders to gather technical data and support procurement and delivery processes
Support the achievement of project milestones by contributing to technical reports, presentations, and design documentation
Communicate clearly with engineers, scientists, technicians, and external partners
Support development trials, installation, and testing activities in the UK and internationally
Requirements:
Hold a degree in Chemical or Process Engineering
Have up to 3 years of industrial experience (or relevant internships/placements)
Have a solid foundation in core chemical engineering principles, including mass and energy balances, thermodynamics, and transport phenomena
Are enthusiastic about hands-on engineering and motivated to learn through practical experience
Are organised, detail-oriented, and willing to take ownership of tasks in a lean team
Communicate effectively and enjoy collaborating across disciplines and environments
Nice to have:
Exposure to lab or pilot plant operations or industrial process environments
Familiarity with standard engineering documentation (e.g. PFDs, H&MBs, equipment specifications)
Understanding of process safety concepts such as HAZOP or FMEA
Exposure to pyrometallurgy, refractory systems, high-temperature processes, minerals processing, or solids handling equipment
