Joining Arup

Arup's purpose, shared values and collaborative approach has set us apart for 80 years, guiding how we shape a better world.

Our process chemical and process engineering team comprises specialist chemical engineers, scientists and industrial experts who shape everything from conceptual design ideas through pre-FEED and FEED to completed turnkey facilities. We support projects at all stages of delivery, ensuring safe, regulatory compliant solutions. We focus on design development, process optimisation, debottlenecking and control of chemical, physical, and biological process, from hydrogen production to carbon capture and transformation through to water and wastewater treatment.

The Opportunity

We are looking for a candidate with a background in process engineering design on multi-disciplinary projects within the municipal and industrial water sectors. With our depth and breadth of skills, our team is currently involved in many exciting projects across the Energy, Water and Resources sectors. Whilst the team is based across the North of England, much of our work involves supporting projects internationally, integrating with teams in our offices across the globe.

The successful candidates are likely to have design experience of the following: fixed and suspended growth systems, anaerobic treatment of biosolids and high-strength effluent, biogas handling and upgrading, membrane separation, solids filtration, disinfection, oxygenation, thermal hydrolysis, nutrient removal processes, chemical storage and dosing systems, along with some experience of HazOp, DSEAR, COMAH, SIL determination, flammable gas handling and compression.

What you’ll do

You will co-ordinate the work of others and liaise with engineers of other disciplines, imparting your knowledge and experiences. You will be working in highly regulated sectors, within a gated design and project delivery process.

You will be responsible for process audits, investigations, feasibility studies, and the outline and detailed design of drinking water treatment works and associated systems.

You will also be involved in report writing and the development of fee proposals and feasibility studies of plant operating and capital costs. We would expect you to have a practical comprehension of how your designs will be implemented, and of digital approaches to solve our problems, including the relevant current analysis and design software.

We operate an enviable graduate training scheme, which is accredited by the IChemE, and as a senior engineer you will be expected to join the mentoring programme and help to shape our future pipeline of process engineers

What we’re looking for

• Strong knowledge of water chemistry and drinking water treatment processes, including membrane separation systems

• Experience in process design, including mass balances, P&IDs, and water treatment hydraulics

• Experience delivering process audits, feasibility studies, investigations, and outline/detailed design of drinking water treatment works

• Ability to develop client briefs, proposals, and presentations

• Collaborative approach, working effectively with colleagues, clients, and external partners

• Experience supporting and mentoring junior engineers and early careers staff (including line management where applicable)

• Degree in Engineering and Chartered Engineer status (or close to obtaining chartership) required
