Senior ​/ Principal Mechanical Engineer

Some engineers spend years waiting for an opportunity to lead.

Others choose a business that's already creating them.

If you're looking for a consultancy where progression isn't just talked about, it's happening all around you, this could be your next move.

Join one of the UK's most respected independently owned Building Services consultancies and become part of a business that's investing heavily in its future leaders.

Whether you're an established Senior Engineer ready to step into a Principal role, or already operating at Principal level, you'll have the opportunity to influence projects, mentor engineers and build a genuine pathway towards Associate and beyond.

You'll join a collaborative Mechanical team delivering technically challenging projects across healthcare, education, commercial, residential, science & technology, defence and advanced manufacturing. The role offers the perfect balance of hands‑on engineering, project leadership and client engagement, giving you the autonomy to make decisions while remaining technically involved.

This is a consultancy that believes progression should be earned, not waited for. With a strong pipeline of work, continued growth across multiple UK offices and a genuine commitment to developing its people, you'll be surrounded by experienced engineers who enjoy sharing knowledge and helping others succeed. Add in agile working, outstanding professional development, enhanced family benefits, bonus schemes and an excellent team culture, and it's easy to see why people build long‑term careers here.

You're already delivering quality Mechanical Building Services projects and you're ready for more. More responsibility, more influence and more opportunity to shape your own career. You'll have consultancy experience, enjoy working directly with clients and be motivated by joining a business where your next promotion is based on your ability, not simply on time served.
