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
