Senior Data Scientist - FDI Scale up - Belfast

MCS Group are delighted to be working with an exciting, fast-growing global SaaS business that is building an AI-driven platform helping some of the world's largest companies understand and improve profitability.

Their platform brings together financial, sales, HR, and operational data into one place, giving businesses a clear, real-time view of where they are making and losing money - right down to transaction level, powered by AI and advanced analytics.

They already work with major international clients across the US, Europe, and EMEA and are now establishing a new engineering hub right here in Belfast. The engineering and data function is scaling, with a strong leadership team and a growing AI / data research capability.

This is a Senior Data Scientist role for someone who enjoys a mix of hands-on building and research-driven problem solving.

You won't just be building dashboards - you'll be helping shape how the product understands and predicts profitability using real-world, often messy financial data.

You'll be:

• Building financial and data models to understand profit drivers
• Working with complex, messy datasets (finance, sales, operational data)
• Using Python to clean, structure, and model data
• Applying AI / LLMs to generate deeper commercial insights
• Experimenting with new modelling approaches and analytical methods
• Helping define how the product evolves from a data and AI perspective
• Turning real-world business data into usable, scalable intelligence

• Strong Python skills (daily, hands-on use)
• Experience working with real-world, messy datasets
• Strong commercial understanding (revenue, cost, margin, profitability)
• Comfortable moving between data exploration, modelling, and production thinking
• Exposure to AI / LLMs (or strong interest in this space)
• Understanding of data pipelines / APIs / how systems connect
• Cloud experience (nice to have, not essential)

This is a rare opportunity to join a small but high-impact AI/data team at the core of a scaling global product. It's a blend of data science, experimentation, and product innovation, focused on solving real commercial problems - not just reporting on them.
