Mechanical Engineer Jobs

Mechanical engineering in Ireland sits at the crossroads of several booming sectors — HVAC and building services, pharmaceutical manufacturing, data centres, and medtech — and with 227 active roles the career path offers both depth and geographic spread across Dublin, Cork, Limerick, Galway, and the midlands.

Johnson Controls is the standout recruiter, with positions across two Cork entities and a particular focus on its Apprentice HVAC Service Engineer programme. Based initially in Cork but covering the Southern Counties with national travel, the programme requires just a Junior Cycle or Leaving Cert with Grade D in five subjects including Maths and English. Apprentices spend significant time at client sites servicing, maintaining, and repairing heating, ventilation, and air conditioning systems across environments including sports facilities, hospitals, and commercial buildings. It's one of the clearest earn-while-you-learn entry points into engineering on HiringNow.ie.

At the experienced end of the market, the demand shifts toward specialist design and sustainability roles. Amazon is recruiting a Senior Mechanical Sustainability Engineer in Dublin to drive carbon reduction in data centre design across its EMEA portfolio — working directly on Amazon's Climate Pledge commitment to reach net zero by 2040. PM Group in Dublin hires Principal and Lead Structural Engineers for pharmaceutical and data centre projects, with responsibilities including managing teams of engineers, designers, and technicians to develop structural packages for tender and construction.

The pharma and medtech corridor adds significant depth. PCI Pharma Services at its City North Business Campus in Stamullen, Co. Meath recruits Maintenance Technicians for night shifts (Thursday to Saturday, 7pm to 7am), where the role involves machine changeovers, planned maintenance, fault-finding on electrical and mechanical systems, and PLC programming — all within GMP compliance. Dexcom at its Athenry, Co. Galway facility — a pioneer in continuous glucose monitoring with over 25 years in the medtech space — is hiring technicians for day shifts through 2026/2027. Veolia Ireland, the country's leading environmental services company, recruits Utilities Shift Technicians in Athlone, Co. Westmeath with a benefits package that includes full VHI cover, pension, and education assistance.

What qualifications tie these roles together? The spread runs from apprentice-level trade qualifications through to chartered engineer status. Core skills in demand include CAD (AutoCAD and Revit), HVAC design, pipe fitting, MEP coordination, and increasingly PLC programming and building management systems. For the pharmaceutical and medtech sectors, familiarity with cleanroom environments, GMP documentation, and validation protocols significantly strengthens your candidacy. Whether you enter through an apprenticeship or a Level 8 engineering degree, this is a career path with clear progression from technician through to principal engineer and design lead.
