Data Scientist Jobs

Data science sits at the intersection of statistics, engineering, and domain expertise, and with 59 active roles it represents one of Ireland's most technically demanding career paths. Dublin accounts for 44 positions, with Limerick and Cork each contributing 5.

UnitedHealth Group leads with 5 positions, applying data science to healthcare outcomes and insurance operations at scale. Analog Devices at Raheen Business Park, Limerick recruits 4 data scientists for sensor-level AI and edge analytics — a unique intersection of hardware and data science. Intercom at St. Stephen's Green has 4 roles for data scientists building models that power its AI customer service agent Fin. PayPal recruits 4 data scientists working on fraud detection, risk modelling, and payment optimisation for hundreds of millions of transactions.

The consulting and pharmaceutical sectors add diversity. EY hires data scientists for client-facing advisory engagements. Novartis recruits 3 data scientists for its Dublin operations, applying advanced analytics to drug development and commercial operations. iCIMS has 3 positions for data science work in HR technology. Fisher Investments applies data science to wealth management and investment decision-making.

F5 adds network analytics and cybersecurity data science from its Dublin engineering centre, while Canonical recruits for Ubuntu telemetry and product analytics.

What separates data science from data analysis? The key distinction is model building: data scientists design, train, and deploy machine learning models and statistical models that make predictions or automate decisions. The core skills include Python (NumPy, pandas, scikit-learn), SQL, statistical modelling, experiment design (A/B testing), and increasingly deep learning frameworks (PyTorch, TensorFlow). A Master's degree or PhD in a quantitative discipline is common though not universal. The career path runs from Data Scientist through Senior Data Scientist to Staff Data Scientist, Principal Data Scientist, and Head of Data Science — with the distinction from related paths in data engineering and machine learning engineering becoming increasingly important as companies build specialised teams.
