I'm working with a growing engineering design consultancy with an expanding workload across the water, utilities and rail sectors, who are looking to appoint an experienced Principal Process Engineer.

This is a senior technical position for a Chartered Engineer with significant experience working on projects for regulated water companies.

You'll combine hands-on process design with technical leadership, design assurance and mentoring, working on a growing portfolio of wastewater treatment projects across the UK.

The Role:

• Lead the development of efficient and practical process design solutions

• Review control philosophies and commissioning strategies
• Provide technical guidance across multidisciplinary project teams
• Support tenders, technical proposals and project planning
• Estimate design hours and contribute to project programmes
• Direct, mentor and develop engineers and graduates
• Lead and participate in HAZOP, ALM, KM and other technical review meetings
• Ensure designs comply with relevant technical standards, professional guidance and water company requirements
• Review design changes and ensure they are appropriately implemented and recorded
• Contribute to the continued development of process engineering standards and best practice

Your initial project will focus on optioneering sewage treatment works capacity increases, before moving onto a wider portfolio of projects including:

• Outline designs for sewage treatment works upgrades
• Capacity improvement and treatment optimisation
• Projects for a range of regulated water companies across the UK
• A growing pipeline of water and wastewater design work

What You'll Need:

• Experience across both clean water and wastewater
• Experience leading or participating in HAZOP studies, ideally as Chair
• Experience supporting tenders and technical proposals
• Full UK driving licence and access to a vehicle
• £65,000–£80,000, depending on experience and working arrangements
• Join a growing consultancy with an expanding water and utilities workload
• Work on projects for multiple regulated water companies across the UK
• Take genuine technical ownership rather than simply delivering individual design packages
• Opportunity to mentor and develop engineers within a growing team
• Hybrid working can be agreed, with up to 3 days working from home for the right candidate
• Occasional site visits only, with travel expenses covered
• Full-time permanent position with a strong focus on training and professional development
