Warrington
£50,000 - £65,000 DOE + Benefits
We're working with a growing integrated MEP and building physics consultancy with offices in Yorkshire and the North West. They deliver mechanical, electrical, and sustainability design across a broad range of sectors, residential, commercial, education, industrial, and retail - and they're looking for a Senior or Principal Mechanical Engineer to join their expanding team.
This is a consultancy that does things properly. Design continuity runs all the way through to site, so you'll actually see your work get built - not hand it off at Stage 3 and move on. They have a real emphasis on buildability from the earliest design stages, and the business is fully digitally operational with Revit Coordinators working alongside the engineering team on every project.
At Senior level, you'll be taking ownership of mechanical design across a live and varied project portfolio, working closely with electrical engineers, building physics specialists, BIM coordinators, architects, and main contractors. At Principal level, you'll be doing all of that whilst also leading a small team, mentoring junior engineers, and playing an active role in client relationships.
The Warrington office is going through an advanced period of growth, and this is a role where the right person will have genuine influence - on projects, on people, and on the direction of the team.

The Culture
This is a team where people are trusted to get on with the job. There's no hierarchy for the sake of it - everyone has a voice, decisions are made collaboratively, and individuals are actively supported in developing their careers and building their own reputation in the market.
You won't be passed from team to team as a project progresses. The same engineers who design it see it delivered, which means the work is taken seriously at every stage - and at Senior or Principal level, that continuity gives you real accountability and real visibility on the projects you lead.
