Working flexibly from the Birmingham office, you’ll visit client sites and collaborate with teams across multi-year frameworks. As part of our thriving business, you’ll take on rewarding multi-disciplinary projects from inception to delivery, creating innovative solutions that enhance the environment and improve communities.

Here’s what you’ll do:

• Develop feasibility studies, outline and detailed designs, and provide construction support.
• Create design drawings, select mechanical plant, and prepare technical specifications.
• Collaborate with multidisciplinary teams, including civil, electrical, process, and mechanical engineers.
• Ensure high technical quality, contribute to bids, and maintain client relationships.
• Manage project budgets, schedules, and deliverables to meet agreed targets.
• Design mechanical installations for water and wastewater systems, including pumps, screens, valves, and odour control.
• Conduct site surveys and liaise with clients, contractors, and suppliers.
• Produce layouts, technical specifications, datasheets, and P&IDs for system designs.

As well as providing innovative and industry leading MEICA solutions to Clients, the team also collaborates with a wide variety of disciplines from other offices in delivering projects, including a close working relationship with our Enterprise Capabilities centres in India, South Africa and Romania.
