Senior or Principal Mechanical Building Services Engineer

Salary: £55,000-£71,000
Employment type: Permanent
Sector: Infrastructure and Ministry of Justice buildings

We are recruiting a Senior or Principal Mechanical Building Services Engineer for a leading UK infrastructure consultancy.

You will take a key role in the design and delivery of mechanical building-services solutions across infrastructure and Ministry of Justice projects, including prisons and other secure operational facilities.

Depending on your experience, you will either lead the mechanical delivery of individual projects or provide technical leadership across a wider portfolio, supporting multidisciplinary teams and developing more junior engineers.

Key responsibilities
Lead the design of heating, ventilation, cooling, domestic water, drainage and associated mechanical building-services systems.
Prepare and check calculations, specifications, drawings, schedules and technical reports.
Develop projects from initial survey and concept design through detailed design, construction support, commissioning and handover.
Coordinate mechanical designs with electrical, structural, architectural and other technical disciplines.
Undertake surveys and assessments of existing buildings and infrastructure.
Develop practical solutions for refurbishment, upgrade and new-build projects.
Ensure designs comply with Building Regulations, relevant British Standards, CDM requirements and industry guidance.
Manage design quality, project risks, budgets and programme commitments.
Liaise with clients, contractors, suppliers and operational stakeholders.
Provide construction-stage technical support and respond to design queries.
Mentor engineers and technicians.
At Principal level, lead teams, approve technical deliverables, manage resources and contribute to bids and work-winning activities.
About you

You will have:

A degree or equivalent qualification in Mechanical Engineering, Building Services Engineering or a related discipline.
Significant experience designing mechanical building-services systems.
Experience working within a consultancy or multidisciplinary design environment.
Strong knowledge of HVAC, mechanical plant, water services and associated controls.
Experience producing and checking calculations, specifications and design documentation.
Knowledge of Building Regulations, relevant standards and CDM responsibilities.
Experience with AutoCAD, Revit and BIM-led delivery.
Strong client, stakeholder and project-management skills.
Incorporated or Chartered status, or demonstrable progress toward professional registration.

Principal-level candidates should also possess Chartered status or equivalent experience and demonstrate technical leadership, team management, commercial responsibility and client-development capability.

Experience within prisons, courts, government buildings, defence, healthcare, education or other operationally sensitive environments would be advantageous. Candidates must be able to obtain the necessary Ministry of Justice security clearance.

The position offers a competitive benefits package, flexible working, professional development and opportunities to work on technically challenging public-infrastructure projects.
