Principal Mechanical Engineer | Building Services Consultancy | London | Up to £80,000

Were partnering with an ambitious and fast-growing Building Services consultancy based in London that's quickly making its mark in the industry. Since launching in 2020, the business has earned an outstanding reputation for delivering high-quality MEP design solutions, building long-term client partnerships, and securing an impressive level of repeat business.

With a growing portfolio spanning commercial offices, mixed-use developments, retail, industrial, and residential projects, the consultancy is now looking to appoint a Principal Mechanical Engineer to play a pivotal role in its next phase of growth.

If you're looking for a genuine leadership opportunity within a dynamic, entrepreneurial consultancy where your ideas and expertise will directly shape the future of the business, this could be the perfect next step.

* Lead the mechanical design and delivery of a diverse range of commercial, mixed-use, refurbishment, and fit-out projects.
* Manage projects through all RIBA Stages (1-6), ensuring successful technical and commercial delivery.
* Build and maintain strong relationships with clients, architects, contractors, and key project stakeholders.
* Take full responsibility for project delivery, ensuring quality, programme, and commercial objectives are consistently achieved.
* Oversee surveys, technical reports, specifications, calculations, and detailed mechanical designs.
* Coordinate mechanical designs, BIM models, technical submissions, and drawing packages.
* Carry out site inspections, commissioning reviews, and provide technical support throughout each project lifecycle.
* Ensure designs comply with current Building Regulations, CDM requirements, sustainability objectives, and industry best practice.
* Mentor and develop junior engineers, fostering technical excellence across the team.
* Support business development through client engagement, fee proposals, recruitment, and identifying new opportunities.

About You

You'll ideally have:

* 10+ years experience within Building Services Mechanical Design.
* A degree in Mechanical Engineering or a related discipline.
* 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.
* A collaborative and supportive working environment where your ideas and contributions are valued.
* Exposure to a varied portfolio of commercial, mixed-use, retail, industrial, and residential projects.
* Genuine autonomy, responsibility, and long-term career progression within a growing business.
