Senior Data Scientist - AI & Machine Learning - FinTech

I’m working with a well established FinTech that is investing heavily in Data Science, Machine Learning and Generative AI. They are looking for a technically strong Senior Data Scientist to join their growing team and work on a range of high-impact, real-world AI solutions.

This is a hands-on role with the opportunity to own projects end-to-end - from identifying and framing problems through to developing, deploying and improving production-ready solutions.

You’ll work across predictive modelling, machine learning, time-series forecasting and modern Generative AI, helping turn complex datasets and business challenges into practical technology solutions.

You’ll be involved in:

• Developing and deploying machine learning and predictive models
• Building LLM-powered applications, AI agents and multi-step workflows
• Working with modern frameworks such as LangChain, LangGraph or similar
• Developing scalable, production-grade Python solutions
• Working with large and complex datasets, including time-series data
• Taking ownership of projects from problem definition through to production
• Collaborating with engineers, analysts, product teams and senior stakeholders
• Exploring new developments across Generative AI, LLMs and agentic AI
• Mentoring junior team members and helping raise technical standards

Experience

• 3+ years’ experience in Data Science, Machine Learning or a related field
• Expert-level Python with strong experience across Pandas, NumPy, SciPy and Scikit-learn
• Strong machine learning and predictive modelling experience
• Hands-on experience with LLMs / Generative AI
• Experience building AI applications beyond basic chatbot interfaces
• Strong understanding of time-series modelling / forecasting
• Experience taking models or AI solutions into production
• Familiarity with Snowflake, AWS, GCP or equivalent cloud technologies
• MSc or higher in Mathematics, Statistics, Econometrics, Physics or another quantitative discipline

This is a great opportunity for a Data Scientist, Machine Learning Engineer or AI Engineer who wants to work with modern AI technologies while having genuine ownership and commercial impact.
