  • Interpreting operational data and identifying opportunities for process improvement
  • Providing practical, implementable recommendations to improve efficiency, compliance, and cost performance
  • Supporting commissioning of new or upgraded treatment systems
  • Writing clear technical reports and presenting findings to clients
  • Managing your own projects from proposal through to delivery, including planning, resourcing, and client communication
  • Collaborating with internal teams and external contractors to deliver successful project outcomes
  • Supporting the development of standard procedures, quality systems, and health & safety documentation (RAMS, permits, etc.)
  • Building strong relationships with clients and contributing to business development activities

Essential Skills & Experience

  • Degree (BSc/BEng or higher) in Environmental Engineering, Chemical Engineering, or a related field
  • Experience in water, wastewater, or environmental consultancy/industry
  • Strong understanding of:

Process engineering fundamentals

  • Experience working on industrial or water utility sites
  • Project management experience (planning, coordination, delivery)
  • Confident communicator with experience presenting to clients
  • Strong data analysis and report writing skills
  • Good understanding of site equipment (e.g. pumps, mixers, aeration systems)
  • Knowledge of health & safety requirements on operational sites (RAMS, permits, inductions)
  • Full UK driving licence and willingness to travel

Sounds interesting, apply direct!
