Key Responsibilities
Technical & Design Leadership
- Lead the mechanical design of municipal water and wastewater treatment projects across the UK, covering feasibility, optioneering, concept, outline and detailed design across major programmes (e.g. AMP8, WINEP, SROs, etc).
- Set and uphold the mechanical design approach for treatment work: in-house standards (in line with water industry asset standards), checking, and consistency of outputs across projects and teams.
- Fulfil Designer duties under CDM 2015 for mechanical works, ensuring effective hazard identification and risk reduction and, where designated, supporting or undertaking Principal Designer responsibilities on assigned projects.
- Take ownership of the mechanical scope within multidisciplinary delivery, driving clear decisions on operability, maintainability, access, and whole-life performance.
Client Engagement & Delivery
- Act as a senior client-facing technical lead, running workshops and design reviews, advising clients, and building long-term relationships with regulated water stakeholders.
- Provide design assurance and technical support during delivery phases, including reviewing contractor submissions, answering design queries, and supporting handover/commissioning activities when required.
Business Growth & Team Development
- Grow the mechanical capability through business development and work winning: identify opportunities, shape scopes, contribute to bids, and build a healthy forward pipeline.
- Help translate the UK water growth strategy into practical actions: target sectors, priority accounts, capability gaps, and delivery plans focused on treatment.
- Build the mechanical arm of the UK water consultancy team through recruitment, mentoring and skills development, including pathways, coaching and technical governance.
Qualifications
What do we need from you
- BEng/MEng (or equivalent) in Mechanical Engineering.
- Registered as a chartered engineer (CEng) or equivalent professional membership (e.g., IMechE or similar).
- Strong track record in the UK regulated water market, focused on municipal water and/or wastewater treatment.
- Demonstrated leadership across the design lifecycle: feasibility/optioneering, concept, outline and detailed design, plus support through delivery stages as the designer.
- Practical depth in treatment mechanical engineering: selecting and specifying equipment, integrating packaged plant, and producing/reviewing high-quality design documentation.
- Working knowledge of UK water industry standards, regulatory expectations, and safety-by-design/CDM as applied to treatment facilities.
- Experience supporting projects delivered via frameworks, alliances and/or D&B models, including design review, technical query response, and design assurance.
