About the Role
The UK water sector is entering a period of unprecedented investment and transformation. Egis is rapidly expanding its Water Business in the UK and is building a high-performing Process Engineering team to help shape this next chapter. As a Process Engineer, you will play a meaningful role in delivering major water and wastewater programmes across the UK municipal and industrial sectors. Working within a collaborative, multidisciplinary environment, you will contribute to technically robust, sustainable, and innovative treatment solutions on nationally significant projects. This is a rare opportunity to join at a key stage of Egis’ UK growth journey, helping to establish, shape, and expand a process engineering capability built on global infrastructure expertise and a long-term commitment to the sector.

Key Responsibilities
Contribute to process design packages across feasibility, optioneering, concept, outline, and detailed design for UK water and wastewater treatment projects. Prepare process calculations, mass balances, basis of design reports, process flow diagrams, P&IDs, sketches, datasheets, schedules, and technical notes under senior guidance. Support option development, treatment process selection, hydraulic and process capacity checks, and assessment of existing treatment assets. Attend site visits, asset surveys, and data collection activities, including discussions with operators, suppliers, and technology providers. Collaborate with Mechanical, EICA, civil/structural, architectural, and construction teams. Contribute to design and operational safety studies such as HAZOP, SWIFT, DSEAR, HAC/HAP, and CDM/safety-by-design reviews. Use spreadsheets, process tools, data analysis, and modelling/simulation outputs to support evidence-based design decisions. Support contractor and supplier reviews, technical queries, commissioning strategies, performance testing, and handover where required.

Experience
Typically 4+ years’ relevant process design experience in water, wastewater, and/or biosolids/sludge treatment design. Proven experience preparing process design deliverables such as calculations, mass balances, process flow diagrams, P&IDs, basis of design reports, and technical specifications. Understanding of water/wastewater treatment processes, process safety, CDM/safety-by-design, and quality assurance processes. Ability to work effectively within multidisciplinary teams to deliver integrated, buildable, and operable treatment solutions. Good digital capability including Excel and relevant process calculation, data analysis, or modelling tools. Willingness and ability to travel to operational works, construction sites, and supplier facilities as required.

About you
Motivated and collaborative professional eager to contribute to sustainable water infrastructure projects. Strong communicator with the ability to engage with operators, suppliers, and multidisciplinary teams.
