About the Role Im hiring on behalf of our client, a leading multi-disciplinary engineering consultancy, to fill a Senior Mechanical Design Engineer vacancy. You will design and specify advanced mechanical systems across high-profile commercial, residential, data centre, utility, and infrastructure developments working from concept through completion under best-practice and regulatory standards. Projects Youll Be Working On: Landmark commercial headquarters projects demanding sustainable, energy-efficient mechanical system design and BREEAM/LEED compliance, akin to the Central Bank of Ireland HQ. Mixed-mode ventilation and bespoke faade integration, delivering high-performance heating, cooling, and ventilation systems tailored for intelligent building envelopes. Infrastructure and site development works, such as canal dredging or site-wide utility layouts, requiring detailed mechanical design coordination across civil, structural, and MEP engineering disciplines. What Youll Do Design and specify HVAC, drainage, water services, ventilation, and BMS solutions that meet sustainability and performance benchmarks. Lead pre-construction design tasks: producing tender drawings, equipment schedules, and service coordination packages. Oversee construction-phase duties, including submittals, RFIs, and site inspections. Collaborate with architects, civil/structural engineers, contractors, and vendors to ensure a fully coordinated mechanical design. Mentor junior engineers, fostering their development in mechanical design processes and standards. What Youll Bring Minimum 7 years experience in mechanical and building services design in Ireland. Deep technical expertise with Irish Building Regulations, CIBSE codes, IS/EN standards, and sustainability frameworks (e.g. BREEAM, LEED). Proficiency in AutoCAD, Revit, and building performance analysis tools (e.g. IES or analogous software). Strong analytical and design skills: competent in heat load calculations, ventilation design, pressure drop analysis, and ductwork/piping engineering. Demonstrated ability to manage drawing revisions and support procurement processes. Excellent leadership, communication, and team coordination skills. Third-level degree in Mechanical or Building Services Engineering. Chartered Engineer status (or actively working towards it). Whats Offered €70,0000 - $80,000 + competitive bonus structure.
