Not Just Another Drainage Engineer Role...

We're looking for an exceptional drainage engineer—someone who enjoys solving the jobs that other engineers can't.

This is a rare opportunity to become the founding technical lead of our growing SewerFix division. You won't simply be carrying out drainage works; you'll play a key role in shaping the future of the business, influencing how the division develops, helping to recruit and mentor future engineers, and becoming the technical expert customers and colleagues rely on.

If you're the engineer everyone calls when they can't find the problem, we'd love to hear from you.
