We’re in the top 5% of utility companies worldwide for employee engagement, and we’re equally proud of our strong Glassdoor score — reflecting how much our people love working here.  Join us to make a positive impact on the environment and our communities, while being valued and supported in a truly inclusive workplace. 

If you want to do more, because you care, we want you on our team. 

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.

 

ABOUT THE ROLE

Within our Capital Design and Delivery department, we are looking for a Design Engineer with a Civil Engineering background and experience in wastewater hydraulic modelling to join our Waste Treatment team based at our Finham Hub in Coventry.

If this sounds like you, this could be the opportunity you’ve been looking for!

 

WHAT YOU’LL DO

In this role, you will support the development and delivery of engineering solutions for Severn Trent Water projects, with a particular focus on hydraulic modelling and civil design.

  • Developing and undertaking hydraulic modelling using HADES to support wastewater treatment and infrastructure projects.
  • Gathering and reviewing the information required to develop hydraulic models, including survey data, levels, flows, asset information and other design inputs.
  • Building, running, reviewing and checking hydraulic models to support engineering design decisions.
  • Interpreting modelling results and ensuring that proposed solutions comply with relevant Severn Trent standards, specifications and design requirements.
  • Using hydraulic modelling to support optioneering, outline design and detailed design.
  • Producing clear modelling outputs, calculations and technical information for inclusion within design packs.
  • Supporting civil engineering design activities across wastewater treatment works and biosolids/bioresources sites.
  • Undertaking appropriate design checks and reviews and contributing to the overall quality of engineering deliverables.
  • Working collaboratively with engineers from other disciplines and internal and external stakeholders.
  • Considering health, safety, environmental and buildability requirements throughout the design process.
  • Supporting projects to meet programme, quality and cost requirements.
  • Projects will range from smaller improvement schemes through to significant wastewater treatment and infrastructure projects. 

 

WHAT YOU’LL BRING

We are particularly interested in candidates with practical experience of HADES hydraulic modelling within the water or wastewater industry.

You may already have experience working on wastewater treatment works, sewerage networks or other infrastructure projects and be looking for an opportunity to develop your technical and design engineering career within an in-house design team.

 

You may also have:

  • A strong technical foundation and enjoy solving engineering problems and working collaboratively to deliver practical solutions.
  • A degree or equivalent qualification in Civil Engineering or a relevant engineering discipline.
  • Experience in gathering, reviewing and interpreting engineering data and using it to develop hydraulic models and design solutions.
  • Experience contributing to engineering projects through optioneering, outline and/or detailed design stages.
  • A full UK driving licence.
  • It would also be beneficial if you are actively working towards Incorporated Engineer (IEng) or Chartered Engineer (CEng) status. We’re keen to support you on that journey.

 

Most importantly, you’ll bring a positive, collaborative attitude and a willingness to learn share knowledge and support the wider team.

We value the right technical skills and experience, but we also value character, positivity and a caring attitude.

We do more, because we care.
