Process Engineer – Water/Wastewater (PE)

We are seeking an experienced Process Engineer to support the planning, design and delivery of water and wastewater treatment projects. This role will suit a technically capable professional who can develop practical, sustainable solutions and work effectively with multidisciplinary teams, clients, contractors and operational personnel.

You will contribute across the full project lifecycle, from feasibility studies and process selection through to detailed design, commissioning and operational support. The position offers the opportunity to work on a varied portfolio of infrastructure and treatment projects, helping to improve asset performance, regulatory compliance and environmental outcomes.

Key responsibilities

  • Develop process designs, calculations, specifications, technical reports and design documentation for water and wastewater treatment systems.
  • Assess treatment processes, hydraulic performance, mass balances, equipment requirements and energy efficiency.
  • Prepare and review process flow diagrams, piping and instrumentation diagrams, process descriptions and control philosophies.
  • Support feasibility studies, option appraisals, risk assessments, cost estimates and programme development.
  • Collaborate with civil, mechanical, electrical, control and environmental engineering disciplines to deliver integrated designs.
  • Provide technical input during construction, commissioning, testing and performance verification activities.
  • Review contractor submissions, respond to technical queries and ensure designs meet applicable standards and regulatory requirements.
  • Engage with clients and stakeholders, clearly communicating technical information to both specialist and non-specialist audiences.

About you

You will have a degree or equivalent qualification in chemical, civil, environmental or process engineering, together with demonstrable experience in the water or wastewater sector. Professional registration, or progress towards registration, is desirable. Experience with treatment technologies, process modelling, design software and industry standards will be advantageous.

You should be commercially aware, well organised and confident managing competing priorities. Strong written and verbal communication skills are essential, along with a proactive approach to problem-solving and a commitment to health, safety, quality and environmental performance.

A full driving licence and willingness to travel occasionally to project and client sites may be required.
