About Us

We’re a specialist provider of advanced wastewater treatment solutions, delivering sustainable infrastructure across municipal and industrial sectors. We're not a corporate machine — we're a focused, technically driven business where your ideas actually shape outcomes.

The Role

We're looking for a hands-on, technically sharp Process Engineer to join our growing team. You’ll work on the full lifecycle of projects — from initial concept and design through to commissioning and optimisation. This role demands someone who understands the real-world challenges of wastewater treatment, not just the theory.

Key Responsibilities

• Design and develop wastewater treatment processes for new and existing plants (biological, chemical, physical treatment).
• Undertake mass balances, process modelling, and simulations (e.g., BioWin, GPS-X, or similar).
• Produce PFDs, P&IDs, and support equipment selection/specification.
• Lead or support commissioning and plant performance testing/troubleshooting.
• Collaborate with design engineers, project managers, clients, and subcontractors.
• Prepare and review technical documentation, calculations, and process reports.
• Support bids and proposals with technical input and process innovation.

About You

• Degree qualified in Chemical, Process, Environmental Engineering, or similar.
• 3–10 years' experience in wastewater treatment — preferably hands-on in the UK market.
• Strong technical understanding of biological and chemical treatment processes (e.g., activated sludge, MBRs, nutrient removal).
• Able to balance office-based design with occasional site work and commissioning.
• Skilled communicator — able to explain the “why” behind your design decisions to clients and colleagues.

Desirable but Not Essential

• Chartered or working towards Chartership (IChemE, CIWEM, etc.).
• Experience with DfMA, modular systems, or smart/automated process control.
• Exposure to industrial effluent treatment.
