A Senior Mechanical Design Engineer is required for a well-established Building Services consultancy with over 60 years of industry experience and a workforce of more than 100 employees. The business has built a strong reputation across commercial, residential, hospitality, and mixed‑use developments and is continuing to expand its London presence due to increasing client demand and a growing project portfolio. This is an excellent opportunity to join a growing London team at an exciting stage of its development.

With the backing of a large, established consultancy, but the feel of a small and collaborative office, the successful candidate will play a key role in shaping the future growth of the business. You will work on a wide range of high‑profile projects, mentor junior engineers, manage client relationships, and have genuine opportunities to progress as the London office continues its planned expansion over the coming years.

• Manage projects throughout the full lifecycle from RIBA Stage 1 through to handover.
• Produce mechanical calculations, technical specifications, reports, and detailed design information.
• Attend client, design team, and project meetings as a key technical representative.
• Coordinate designs with architects, structural engineers, contractors, and wider project teams.
• Support and mentor junior and intermediate engineers within the business.
• Review project deliverables to ensure technical accuracy and compliance with current regulations and standards.
• Build and maintain strong client relationships while supporting repeat business opportunities.
• Work collaboratively with colleagues across the wider engineering team to deliver high‑quality projects.
• Experience in public health design would be advantageous, although this is not essential.

• Minimum of 5 years' experience within a Building Services consultancy environment.
• Strong experience delivering mechanical designs on large‑scale commercial, residential, hotel, PBSA, or mixed‑use developments.
• Ability to manage projects independently and confidently engage with clients and stakeholders.
• Experience across detailed design and technical delivery stages.
• Strong understanding of current and upcoming Building Services regulations and standards.
• Commercial awareness and understanding of the construction and development process.
• Proficiency in AutoCAD and Revit.
• Excellent communication skills with the ability to mentor junior engineers and represent the business professionally.
• Strong written and spoken English skills.
• Public health design experience would be beneficial but is not a prerequisite.

• Salary up to £75,000 depending on experience.
• 20 days holiday + bank holidays with additional leave accrued through length of service.
• Private healthcare.
• Company phone.
• Hybrid working arrangement with 3 days in the office and 2 days working from home.
• Flexible working hours with core hours between 9:30am and 3:30pm.
• Opportunity for an early Friday finish through flexible working arrangements.
• Clear career progression opportunities within a rapidly growing London office.
• Central London office location.
