Not demos. Systems that work. * Developing and fine-tuning small and medium language models (SLMs) for regulated banking use cases,



including custom evaluation frameworks and domain-specific benchmarks. * Architecting and implementing MCP servers, A2A protocols, and federated API layers that allow AI agents to operate across the group’s multi-country infrastructure. * Prototyping new ideas in two-week sprints: hypothesis, architecture, code, functional demo, one-pager. This is the lab’s operating rhythm - you need to thrive in it. * Collaborating with researchers, data scientists and business stakeholders to translate complex technical concepts into tangible bank value - Alchemy-style transformations of legacy assets. * Keeping the lab at the frontier: monitoring emerging research, evaluating new tools (Harness Engineering, Kiro, Windsurf, Devin), and integrating them into the lab’s workflow when they add real value. * Producing clean, tested, observable code that can be handed off to the AI Science team for production scaling. You own your code end-to-end. What You’ll Bring Ou
