MCS Group is working with a fast‑growing global SaaS business building an AI‑driven platform that helps some of the world's largest companies understand and improve profitability. The 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. The company already works with major international clients across the US, Europe, and EMEA and is establishing a new engineering hub in Belfast. The engineering and data function is scaling, with a strong leadership team and a growing AI/data research capability.

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.

Responsibilities
  • 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
What they're looking for
  • 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.
