Hours: Full Time

The role and responsibilities:

We are seeking an experienced and motivated Senior or Principal Mechanical Engineer to join our dynamic team. This role focuses on the refurbishment, upgrade, and decarbonisation of existing buildings, and requires a practical, client-facing engineer who thrives in both technical and on-site environments. You’ll play a key role in the delivery of mechanical engineering services from feasibility through to detailed design and construction.

What you’ll be doing:

• Lead mechanical engineering design for projects involving HVAC, domestic water services, and renewable energy systems in existing buildings.
• Conduct condition surveys, asset assessments, and lifecycle costing.
• Deliver decarbonisation analysis, energy audits, and retrofit strategy development.
• Produce technical reports, specifications, and feasibility studies.
• Undertake detailed engineering calculations to inform design and decision-making.
• Liaise with contractors, clients, and stakeholders throughout the project lifecycle.
• Fulfil Contract Administrator duties including managing valuations, contractor performance, and change control procedures.
• Apply knowledge of contract management, especially JCT contracts.
• Conduct regular site inspections, oversee commissioning, and support issue resolution.
• Collaborate closely with electrical engineers, architects, sustainability specialists, and quantity surveyors.
• Mentor and support the development of junior engineering staff.

Qualifications

• Building Services Engineering qualification

Experience

• Proven experience in mechanical design, delivery, and project leadership on existing building projects.
• Familiarity with maintenance contracts, including performance monitoring and lifecycle planning.
• Demonstrated experience writing and contributing to procurement documentation for public or private sector projects.
• Proficiency in writing technical reports, developing specifications, drawings, calculations and conducting feasibility studies.
• Extensive experience working within the social housing sector, as well as across a broad range of public sector environments, including educational facilities (e.g. schools and academies), healthcare buildings, and commercial properties. This includes a strong understanding of the specific challenges, compliance requirements, and stakeholder engagement needs associated with these settings—such as budgetary constraints, phased works in occupied premises, and alignment with government or local authority frameworks and funding criteria.
• Experience in asset data collection, including on-site surveys to identify and log mechanical and electrical systems, capturing equipment condition, operational status, and compliance with relevant standards to support lifecycle planning, maintenance strategies, and investment decisions.
• Knowledge of construction risks, including how to identify and manage them effectively across project stages.
• Experienced in reporting resource and financial information to Partners and senior management, ensuring visibility on project performance and forecasts.

Knowledge

• Thorough understanding of building services systems including HVAC, hot and cold water, and controls.
• Working knowledge of UK Building Regulations, CIBSE guides, BREEAM, and other sustainability frameworks.
• Experience with maintenance contract planning and service level agreements.
• Familiarity with public procurement processes, contract law, and compliant documentation.
• Familiarity with energy and carbon reduction strategies, including low/zero carbon technologies.
• Contract knowledge, particularly JCT forms of contract and contract administration processes.
• Understanding of government funding schemes

Skills

• Strong communication skills – able to lead client meetings and present complex information clearly.
• Analytical thinking – capable of problem-solving and value engineering on live projects.
• Proficient in relevant software such as AutoCAD, and Microsoft Office Suite. An understanding of Revit and IES is desirable.
