* Take full responsibility for project delivery, ensuring quality, programme, and commercial objectives are consistently achieved.

* Mentor and develop junior engineers, fostering technical excellence across the team.
* Support business development through client engagement, fee proposals, recruitment, and identifying new opportunities.

* Membership of CIBSE, IMechE, or another relevant professional institution (or working towards chartership).
* Proven experience delivering commercial, refurbishment, fit-out, and mixed-use projects.
* Strong technical knowledge with proficiency in AutoCAD, Revit, IES VE, Hevacomp, H2X, Bluebeam Revu, and Microsoft Office.
* Excellent communication, report writing, and stakeholder management skills.
* Commercial awareness with an interest in business development, team leadership, and contributing to the continued growth of the business.
Whats on Offer?
* Salary of up to £80,000, depending on experience.
* 28 days annual leave plus bank holidays.
* A clear and structured pathway to Director level.
* The opportunity to play a key role in the growth and future success of an ambitious consultancy.
