About the Job

As a Senior Mechanical Engineer, you will lead the delivery of mechanical building services/ MEP design for energy, industrial and commercial projects within a multidisciplinary building services consultancy environment.

• Carry out continuous design and installation quality checks to ensure compliance with project specifications and applicable standards

• Prepare fully detailed mechanical building services tender packages, technical reports, analyses and recommendations

• Support construction stages through technical queries, site visits and coordination with contractors and vendors

• Take technical ownership of projects, operating with minimal input from senior management

• Mentor, guide and review the work of junior and intermediate engineers, ensuring QA standards are met prior to issue

Technical Skills

• Strong experience in mechanical building services / MEP systems design within a consultancy environment

• Proven expertise delivering HVAC and building services systems for industrial buildings

• Working knowledge of ATEX directives and mechanical design considerations in hazardous environments

• In-depth understanding of CIBSE, ASHRAE, BS, IS and EN standards
