At Severn Trent, our people are at the heart of everything we do. We’re in the top 5% of utility companies worldwide when it comes to employee engagement and are ranked as a Top 50 UK Employer on Glassdoor. Join us in making a positive impact on the environment and our communities, while being valued and supported in a truly inclusive workplace.
Are you passionate about tackling climate change and making a positive impact on the environment? Our ambitious five-year programme, featuring over 5,000 innovative projects, is dedicated to overcoming the challenges of delivering exceptional water and waste services. With our dedicated in‑house design team, we are set to achieve outstanding results and make a significant impact.
We have an exciting opportunity for a Senior Design Engineer (Mechanical, Civil or Process). The role will be based in Raynesway (Derby) and will sit within our expanding major projects and bioresearch waste treatment design team. The Design Team uses technical skills to shape wastewater strategies for the company, providing expert advice to lead projects from feasibility to detailed design.
You will work with stakeholders, consultants and contractors to protect and enhance the quality of our waste‑treatment assets and rivers; interrogate and improve our data systems; undertake investigations and outline designs so that we have the best evidence available for decision‑making.
You’ll be degree qualified (desirable) and showing your professional commitment as a member of one of the engineering institutions or actively working towards incorporated or chartered status, a journey we are keen to support. A water‑industry background would be great but not essential; an engineering discipline is required.
You will have excellent internal and external stakeholder management skills, with the ability to build relationships with a diverse range of people. You will be forward‑thinking, capable of anticipating challenges and responding to change in a rapidly evolving environment. A full UK driving licence will be required.
We value character, positivity and a caring attitude in equal weight.
Working here isn’t just a job. You can build a career at Severn Trent. We’ll reward you for it, too. We have a range of benefits that recognise great work and offer award‑winning training to help you reach your potential.
