Intermediate Mechanical Designer

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.

• 
  
• 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.
  

• 
  
• 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.
  

• 
  
• 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.
  

• 
  
• 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
