This is an opportunity to join a close-knit team of around 25 staff, where you'll play a key role in delivering technically strong, buildable designs across a genuinely varied project portfolio.

You'll be working across sectors including healthcare, MOD, education (from primary schools through to universities), commercial, and residential. Projects range from complex refurbishments through to new build developments, with the added benefit of working both client-side and alongside contractors-giving you well-rounded exposure and a deeper understanding of how projects are delivered on site.

The business prides itself on developing high-quality engineers, with a strong emphasis on practical design and real-world application. You'll be given the autonomy to take ownership of your projects, build client relationships, and support the development of junior engineers within the team.

The Role:

• Lead mechanical design on a range of building services projects

• Engage directly with clients and project stakeholders

• Produce detailed, technically sound, and buildable designs

• Mentor and support graduate engineers

• Contribute to maintaining strong client relationships and repeat business

What They're Looking For:

• Proven experience in mechanical building services design

• Comfortable in a client-facing role

• Ability to lead projects and support junior team members

• Strong technical capability across a range of project types

Why Join?

• Hybrid working (2 days from home)

• Diverse project portfolio across multiple sectors

• Opportunity to influence projects from both client and contractor perspectives

• Supportive, collaborative team environment

• Newly refurbished, modern office space

• Clear scope for progression as the business continues to grow

If you're looking for a role where you can broaden your project exposure, take on more responsibility, and genuinely influence project outcomes-this could be a strong next step.
