Location: Nottingham, UK (On-site — plant delivery role)Remuneration: above market rate + meaningful equity + performance-based bonusStart Date: ImmediateContract Type: Permanent, Full-timeVisa Sponsorship: Available for exceptional candidates only
About UsConcrete4Change (C4C) is building one of the most commercially viable CO₂ mineralisation platforms globally.We are already operating at pilot scale (~3 tonnes/year).Next steps:

Demo plant (~300 tonnes/year)
Industrial plant (~300,000 tonnes/year)

This is a 1000× scale-up, and we are executing it now with major industrial partners (Holcim, Goldbeck).
The RoleThis is a delivery leadership role.We are looking for a Process Engineering Manager who can take full ownership of engineering execution, subcontractors, budget, and delivery — and turn a working process into a fully engineered, operable, and commercially viable plant.Your job is not to design in isolation. Your job is to deliver a plant that works, on time, on budget, and meets performance targets.What You Will Actually Do• Own delivery of the demo plant (~300 t/year) and define the pathway to industrial scale (~300 kt/year)• Lead and manage all engineering activities and subcontractors:

EPC / integrators
equipment suppliers
consultants
internal engineering team

• Translate process risks into engineered solutions:

identify failure modes
design mitigation strategies
ensure robustness at scale

• Own budget, cost control, and financial discipline:

capex planning
supplier negotiation
cost vs performance trade-offs

• Ensure the plant meets technoeconomic and commercial targets:

throughput
cost per tonne
product quality
operability and uptime

• Lead FEED, detailed design, and engineering package development• Own:

PFDs / P&IDs
mass & energy balances
equipment specifications
system integration
Mechanical skid design

• Drive supplier selection, contracting, and performance management• Lead commissioning, debugging, and ramp-up — not just design• Own factory acceptance testing (FAT) and ensure real performance matches design intent• Work closely with chemistry and analytical teams to ensure the process is controllable and stable• Deliver on timeline, budget, and performance — simultaneously
Essential Requirements• Degree in Chemical Engineering• 10–15+ years of experience delivering process plants and scale-up projects (TRL 5–9)• Proven experience managing:

engineering teams
subcontractors
suppliers
project delivery

• Strong experience in:

process design (PFDs, P&IDs, mass balance)
Mechanical design
plant integration
Process control design
commissioning and start-up

• Demonstrated ability to translate technical risk into practical engineering solutions• Strong commercial awareness — understands cost, value, and trade-offs• Experience delivering projects to budget and schedule under pressure• High ownership mindset — no reliance on others to drive delivery
Strong Signals (We Will Prioritise)• You have delivered a demo or first-of-a-kind plant• You have managed EPCs / integrators / complex supplier networks• Experience in CCS, chemicals, energy, or materials processing• Experience with solids, precipitation, crystallisation, or multiphase systems• You have taken responsibility for budget + delivery + performance (not just design)
Benefits• Ownership of scaling a breakthrough process from pilot → demo → industrial• Equity in a company targeting global decarbonisation• Direct engagement with major industrial partners and investors• High-impact leadership role with full delivery responsibility• Fast progression based on results• No bureaucracy — only execution
Final Note (Read Carefully)This role is about accountability.If you want:

to focus only on design
to avoid budget responsibility
to avoid managing subcontractors
or to work without pressure on delivery

this is not the role.If you want to:

own engineering delivery end-to-end
build a real industrial system
and be accountable for cost, performance, and timeline

then apply.
