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.
