Intermediate Mechanical Designer Role Summary We are seeking an experienced Mechanical Designer to join our building services consultancy team. The successful candidate will support the design of mechanical systems for both new-build and refurbishment projects, with a strong focus on sustainability, low carbon design, buildability, and effective delivery from concept through to completion. The role involves collaborating across disciplines, producing detailed mechanical design drawings (CAD & BIM), and ensuring compliance with industry standards and client requirements. Key Responsibilities * Produce mechanical engineering design for HVAC, plumbing, domestic hot water, drainage, and other mechanical building services systems across all project stages (RIBA Stages 1-5). * Develop detailed drawings, specifications, calculations, and schedules using both 2D CAD and 3D BIM tools. * Collaborate with electrical, architectural, structural, and sustainability teams to ensure integrated, buildable solutions. * Ensure designs meet relevant standards, codes, and regulations (e.g. Building Regulations, CIBSE, etc.). * Contribute to the low-carbon / net-zero design strategy: selecting efficient systems, evaluating renewable technologies, optimizing energy performance. * Assist in coordinating with contractors and other stakeholders during design & construction phases to resolve technical issues and clarify design intent. * Carry out review of drawings and designs produced by junior designers or external parties; provide mentoring / guidance as required. * Conduct site visits when necessary to verify conditions, assembly constraints, or installation/interference issues. * Maintain project documentation, version control, and quality assurance in line with company processes. * Support cost estimation and feasibility studies related to mechanical systems, including life-cycle cost and energy modelling where required. Required Skills & Experience * Bachelor’s degree or similar in Mechanical Engineering, Building Services Engineering, or closely related field is preferable. * Typically 3-5 years demonstrated experience in mechanical design within a building services / M&E consultancy environment. * Proficiency with CAD and BIM tools (e.g. AutoCAD, Revit or similar). * Strong technical understanding of HVAC systems, plumbing, heating, ventilation, drainage, and associated components. * Knowledge of energy efficiency, low carbon technologies, sustainable building practices. * Good understanding of UK Building Regulations, standards (e.g. CIBSE, BS), and statutory compliance. * Ability to interpret architectural and structural drawings, coordinate with other disciplines. * Strong communication skills – both written and verbal – to liaise with clients, consultants, contractors and internal teams. * Attention to detail with good problem solving and judgement skills. * Ability to manage own workload, prioritize tasks, and deliver to deadlines. * Willingness to visit sites as required. Desirable Attributes * Experience in Net Zero / low carbon / renewable energy system design. * Knowledge of energy modelling or simulation tools. * Prior exposure to a variety of sectors (residential, education, leisure, industrial). * Familiarity with contract documentation and construction phase involvement. * Leadership qualities: ability to mentor junior staff, review others’ work, take initiative. Working Conditions & Other * Based in Nottingham / U.K., with travel to project sites as required. * Hybrid working potential depending on project requirements. * Competitive salary aligned to experience. * Opportunities for professional development and training in sustainable design and advanced BIM methodologies
