Job description

Summary:

Are you a skilled mechanical engineer looking for a role that offers both technical challenge and a genuine work-life balance?

Do you want to use your expertise to lead meaningful projects that provide a vital service to our community?

As one of our Senior Mechanical Engineers, you’ll provide the technical leadership needed to keep our MEICA team moving forward. This is a varied role where you’ll oversee resource allocation, solve complex mechanical queries, and help deliver capital engineering schemes from the initial design through to commissioning.

Whether you’re an experienced professional looking for a more stable, value-driven environment or a rising talent ready to step into a senior position, you’ll find plenty of opportunity here to make a tangible impact.

Main Responsibilities:

• Develop Technical Solutions: Coordinate with multi-disciplinary teams—including Process and Civil—to create integrated, practical solutions for water infrastructure.

• Lead Design Reviews: Work independently or as part of a team to check, review, and approve complex mechanical designs, calculations, and specifications.

• Oversee Project Delivery: Manage outline scheme designs and ensure all contractor work aligns with company specifications, WIMES, and current legislation.

• Support the MEICA Team: Act as a deputy authorising engineer and provide technical guidance to the mechanical engineers reporting to you.

• Ensure Safety & Standards: Undertake designer responsibilities under CDM regulations and participate in HAZOP/ALM studies to keep our sites and people safe.

• Stakeholder Engagement: Build professional relationships with internal teams and framework partners, representing South East Water at industry working groups.

What you’ll need:

• Industry Experience: A strong background in clean water projects, specifically with treatment plants, pumped systems, and chemical dosing.

• Technical Proficiency: Experience with hydraulic systems, including pump selection, head loss calculations, and an understanding of surge requirements.

• Contract Knowledge: Practical experience working with NEC3 Design & Construct or PSC contracts.

• Organisational Skills: The ability to manage your own workload alongside a team’s, staying calm under pressure and meeting budget constraints.

• Communication: Clear verbal and written skills for report writing and collaborating with diverse project teams.

• Licence: A full, clean UK driving licence is required for regular travel to our Snodland office and various sites across our supply area.
