Mechanical & Electrical Design Engineer

Position: Mechanical & Electrical Design Engineer
Mechanical & Electrical Design Engineer

Water & Wastewater Infrastructure

If you enjoy seeing your designs make a real-world difference, keep reading.

This is a hands-on Mechanical & Electrical Design Engineer role where your work directly shapes water and wastewater treatment facilities — from pump stations and treatment plants to complex network infrastructure.

Demand is growing, projects are increasing, and this role has been created to support a busy and expanding portfolio of work. You’ll be joining a team that values practical engineering, collaboration, and ideas that actually get implemented — not parked in a drawer.

If you want responsibility, variety, and the chance to influence how things are designed and delivered, this Mechanical & Electrical Design Engineer role gives you exactly that.

The Mechanical & Electrical Design Engineer Role — What You’ll Be Working On

You’ll take ownership of mechanical and electrical design activities across a range of water and wastewater projects. No two jobs are the same, and you’ll be involved from early concept through to detailed design and delivery.

As a Mechanical & Electrical Design Engineer, expect to:

* Design mechanical and electrical systems for water and wastewater assets including pump stations, treatment plants, pipelines and valves

* Produce high-quality detailed designs using CAD tools (AutoCAD, Revit, etc.)

* Work closely with civil, process and instrumentation engineers to deliver fully integrated solutions

* Manage your own design deliverables, ensuring quality, programme and budget requirements are met

* Ensure all designs comply with industry standards, regulations and health & safety requirements

* Engage with clients to understand requirements, explain technical solutions and support decision-making

* Contribute ideas that improve efficiency, sustainability and long-term performance of assets

This is a collaborative, roll-your-sleeves-up environment — you’ll have the freedom to step beyond a narrow job description and genuinely influence outcomes.

The Kind of Engineer Who Thrives Here

You’ll do well in this role if you:

* Enjoy solving practical engineering problems, not just producing drawings

* Like working across disciplines and learning how everything fits together

* Are comfortable taking responsibility and managing your own workload

* Want your ideas to be heard and used

* Care about sustainable, well-thought-out design

* Enjoy variety — office design work mixed with site exposure

What You’ll Bring

* 3–5+ years’ experience in mechanical and/or electrical design engineering

* Experience with in the water or wastewater sector (highly desirable)

* A degree in Mechanical Engineering, Electrical Engineering or a related discipline

* Strong CAD capability (AutoCAD, Revit or similar)

* Knowledge of relevant water industry standards and regulations (e.g. WIMES, DSEAR, BS / EU standards)

* A practical, sustainability-focused mindset

Chartered or working toward professional registration is beneficial, but not essential.

Working Environment & Location

* A mix of office-based design work and site involvement

* Site work primarily across the South of England, with occasional nationwide travel

* A varied workload across multiple projects rather than being tied to one narrow area

* A team environment that values flexibility, collaboration and proactive engineers

Why This Mechanical & Electrical Design Engineer Role Stands Out

* Real ownership of design work from concept to delivery

* Direct impact on critical water infrastructure and sustainability outcomes

* A growing workload that offers long-term stability and development

* Exposure to a wide range of projects and engineering challenges

* A culture where engineers are trusted, listened to, and supported
