Data Scientist

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 Gen AI 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 Gen AI 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
• Required Skills & Experience
• 3+ years’ experience in Data Science / Machine Learning roles
• Strong Python and SQL skills with hands‑on experience building models and data pipelines
• Proven experience working with Generative AI (LLMs, prompt engineering, embeddings)
• Experience using frameworks such as Lang Chain, Llama Index, or similar
• Experience integrating with model APIs (e. g. Open AI or open‑source alternatives)
• Exposure to cloud environments (AWS, GCP or Azure)
• Strong problem‑solving skills with a pragmatic, delivery‑focused mindset
• Ability to work in cross‑functional teams within a fast‑paced environment
• Nice to Have
• Experience within financial services or other regulated industries
• Exposure to vector databases (e. g. Pinecone, Weaviate, FAISS)
• Experience with MLOps / LLMOps and deploying models into production
• Familiarity with LLM fine‑tuning, evaluation, or guardrailing techniques
• Experience building internal tools such as copilots or knowledge assistants
• What’s on Offer
• Salary up to £75,000 depending on experience
• Generous benefits package
• Opportunity to join a well‑established business investing heavily in AI
• High‑impact role with real ownership and visibility
• Collaborative and forward‑thinking data team
