Data Scientist
Location: Manchester (Hybrid)
Salary: £60,000 - £75,000 + benefits
The Role
We are working with a well-established financial services organisation undergoing significant investment in its data and AI capabilities.
They are looking for a hands-on Data Scientist to help drive the development and deployment of GenAI solutions across the business. This role is focused on practical application - building and scaling real-world use cases.
You will work on a variety of projects, including intelligent automation, document processing, internal copilots, and customer-facing AI tools, leveraging large language models and modern machine learning techniques.
While the organisation operates in a regulated environment, they are open to candidates from a range of industry backgrounds - financial services experience is beneficial but not essential.
Key Responsibilities
- Design, build, and deploy Generative AI solutions using large language models (LLMs)
- Develop and optimise prompt engineering strategies for production use cases
- Build end-to-end pipelines (RAG, embeddings, vector search) for scalable GenAI applications
- Work with both structured and unstructured datasets, including text-heavy data
- Collaborate closely with data engineering and software teams to productionise solutions
- Identify high-impact use cases and contribute to the broader AI roadmap
- Ensure solutions align with governance, risk, and compliance standards
- Communicate insights clearly to both technical and non-technical stakeholders
