Machine Learning Engineer Jobs

The AI and machine learning market in Ireland is experiencing explosive growth, with 241 active roles spanning everything from agentic AI development at global consultancies to robotics simulation at semiconductor leaders. Dublin dominates with the bulk of positions, but Limerick's semiconductor cluster adds a distinctive hardware-AI dimension that few European cities can match.

The range of employers reflects how deeply AI has penetrated every sector. Analog Devices at Raheen Business Park in Limerick is hiring Principal AI/ML Robotics Simulation Engineers for its Edge AI team — building real-time intelligent systems that combine world-class sensor technology with cutting-edge AI at the edge, where milliseconds matter. This is hardware-meets-AI work that directly leverages ADI's $9 billion semiconductor business. Intercom, at 124 St. Stephen's Green, recruits Senior Product Engineers for its AI Infrastructure team to build the systems behind Fin, which the company describes as the most advanced customer service AI agent on the market, serving nearly 30,000 global businesses.

The financial services sector is a growing source of AI demand. PayPal in Dublin hires Staff Machine Learning Engineers to build ML-powered payment systems for its two-sided network connecting hundreds of millions of merchants and consumers. Citi is recruiting a Director of GenAI Engineering for its Developer Enablement function — a senior technology leader who will own the GenAI roadmap and embed cutting-edge practices into enterprise software delivery. PwC at One Spencer Dock recruits AI Engineers specialising in agentic architectures, including design, testing, deployment, and maintenance of end-to-end GenAI solutions.

The consulting and professional services firms are building out AI practices at speed. EY at Harcourt Centre hires AI Security Senior Managers to lead cyber AI solutions covering data security, privacy, and model security reviews. Welocalize (via its Welo Data subsidiary) at Cherrywood Business Park operates a global network of 500,000+ contributors in 100+ countries, delivering annotation, evaluation, and prompt creation data to train advanced AI systems.

What skills are in demand? The core technical stack includes Python, PyTorch, TensorFlow, and increasingly LangChain and agentic frameworks for GenAI work. For robotics-focused roles, experience with simulation environments, ROS, and reinforcement learning is valued. The career path ranges from AI Operations Intern and Robot Learning Intern through to Staff ML Engineer and Director of GenAI Engineering — with compensation at the senior end reflecting the fierce global competition for AI talent. Whether you're building recommendation systems, training language models, or programming robots to perceive the physical world, Ireland's AI market offers depth across both the research and applied ends of the spectrum.
