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
