• Proven delivery of projects across the full lifecycle: feasibility through to operations
  
• Strong communication skills and a proactive, safety-first mindset
  
• Comfortable in a start-up environment with self-starting, problem-solving attitude
  
• Background in electrolysis, fuel cells, or hydrogen system design
  
• Experience working with supercritical water or oxygen systems
  
• Familiarity with thermal design tools (e.g., HTRI) and CFD
  
• Chartered status
  
• Equity participation through a tax-efficient share scheme
  
• 25 days holiday + public holidays (option to buy 5 more)
