We're partnering with a leading UK fintech to find a Senior Data Scientist with hands-on GenAI experience. This is for someone who wants to work at the cutting edge of applied AI — building production-grade agentic systems that have a real impact on the business.
The Role
This is a hands-on position focused primarily on GenAI, with traditional ML work also in the mix. You'll be designing agentic workflows, building evaluation frameworks, and bridging the gap between experimental prototypes and production reality - enabling teams across the business to build their own GenAI products.
- Designing and implementing core logic for GenAI agents, including tool definitions that allow LLMs to interact with internal systems
- Building systematic evaluation frameworks to measure accuracy, reliability, and tool-use performance
- Developing predictive ML models and analysing business data for opportunities
- Rapidly prototyping applications to validate technical feasibility with stakeholders
- Optimising prompts, reasoning chains, and agentic patterns for production use
- Implementing responsible AI guardrails and adversarial testing
Requirements:
- Hands-on experience building LLM-powered applications — tool use, RAG, agentic frameworks
- Strong, production-quality Python (clean, tested, Git-based workflow)
- Experience evaluating non-deterministic and ML models systematically
- Solid SQL and data manipulation skills
- Ability to translate non-technical business problems into effective technical solutions
