The Anglian Water @one Alliance is a totally collaborative organisation made up of nine partner companies (Anglian Water, SWECO, Balfour Beatty, Barhale, Binnies, MMB, MWH Treatment, and Skanska) and an extended supply chain, delivering over half of Anglian Water’s capital investment programme.

We are gearing up for our most exciting and challenging Asset Management Period yet, known as AMP8, which will see us deliver a programme of work larger than we’ve ever delivered before. We’ll be embarking on a new kind of project delivery focusing on nature‑based solutions like wetlands and urban drainage schemes.

We are driving change, empowering us to set global benchmarks and build a better environment, with the opportunity to offer enhanced growth and development to our workforce.

With such an exciting portfolio of projects planned for AMP8 to keep the water flowing across the region, our ability to manage our work and outperform against our customer’s expectations will come under greater scrutiny.

We need aspiring driven talent to help us achieve our ambitious targets. Are you ready to join us as we prepare to deliver the most creative and innovative AMP we have ever seen?

As our Principal Mechanical Engineer, you'll lead the Senior Mechanical Engineers in designing and delivering cutting‑edge value‑driven mechanical engineering solutions that adhere to water quality standards while reducing carbon, enhancing natural capital, and embracing the challenges of climate change.

• As part of the asset standards governance process identify, support, implement and approve standard products for delivery efficiency and consistency in projects.

• Support the identification of value‑driven solutions at Stage 1 of projects.
• Conduct audits (internal and externa) to ensure compliance with quality standards and specifications.
• Lead the resolution of non‑compliance issues, competency gaps, and procedural improvements.
• Offer expert direction for complex design challenges and stakeholder engagement.

• Drive excellence in compliance with CDM regulations, ensuring safe and compliant designs.
• Conduct audits on mechanical safety standards (e.g., HAZOP, DSEAR) and lead improvements.
• Proficiency and application of Regulation 31 in relation to mechanical assets in water projects.

• Provide technical leadership, mentoring, and career guidance to the mechanical engineering team.
• Champion professional development and qualifications while fostering an inclusive, respectful, and diverse environment.

• Inspire a culture of experimentation, safe failure, and continuous improvement.
• Lead the introduction of new technologies and techniques to advance performance and sustainability.

To thrive in this role, you’ll need a strong background in mechanical engineering, preferably within water treatment or similar industries. Proven leadership experience, with the ability to inspire teams and drive innovation. A deep understanding of sustainability principles, including reducing carbon and protecting natural capital. Excellent communication, collaboration, and stakeholder engagement skills, and a passion for mentoring, professional development, and fostering a positive workplace culture.

If you believe you have the skill set required, are keen to join a business with genuine opportunities for career progression, then we’d love to hear from you.
