Mechanical Design Engineer – Job Description
About the Role
We are looking for a talented Mechanical Design Engineer to join our engineering team. You will be responsible for designing and developing mechanical building-services systems, working on a variety of projects across residential, commercial, education, and special-structure sectors. You’ll help drive efficient, buildable, and high-quality engineering solutions from concept through to completion.
Key Responsibilities
*
Develop mechanical design solutions (HVAC, heating/cooling systems, ventilation, public health) from concept to detailed design.
*
Prepare and produce calculations, specifications, and technical design reports.
*
Create 2D and 3D drawings, using CAD and BIM tools (e.g. AutoCAD, Revit).
*
Collaborate with structural, architectural, and other engineering disciplines to coordinate integrated building designs.
*
Conduct performance analysis (e.g. thermal, airflow) and optimise systems for energy efficiency, cost, and maintainability.
*
Ensure designs comply with UK building regulations, CIBSE guidelines, and relevant sustainability standards.
*
Visit sites to carry out surveys, support construction teams, and resolve design-related technical queries.
*
Participate in design reviews and value-engineering exercises.
*
Assist with project reporting, risk assessment, and quality assurance.
*
Provide technical support during the construction phase, including responding to site design changes and as-built documentation.
Person Specification / Required Skills
*
Degree in Mechanical Engineering, Building Services Engineering, or a related discipline (or equivalent experience).
*
Experience (e.g., 2–5+ years, depending on level) working in building services design consultancy.
*
Proficiency with CAD/BIM tools, such as AutoCAD and Revit.
*
Good understanding of mechanical services (HVAC, heating, hot/cold water systems) and design principles.
*
Strong knowledge of UK building regulations, CIBSE standards, and sustainability frameworks.
*
Analytical mindset: ability to produce and interpret design calculations.
*
Excellent communication and teamwork skills: able to work collaboratively with multidisciplinary teams.
*
Self-motivated, organised, and able to prioritise in a multi-project environment.
*
Willingness to travel to project sites for surveys and design support.
*
Chartered (e.g. CEng) or working towards chartership is desirable but not essential.
What’s On Offer
*
Competitive salary, depending on experience.
*
Opportunities for professional development and chartership support.
*
Exposure to a varied and interesting portfolio of projects, including structural-engineered buildings.
*
Flexible working arrangements / hybrid working.
*
Supportive, innovative team culture
