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
