Build and ship end-to-end AI banking customer experiences on an agentic platform: prototype quickly, create tools via prompts/configuration, design evals to define “good,” and iterate from real customer conversations. Work in the codebase with engineering review, shape production behavior (routing, latency, cost, model choice), and make sound risk/compliance judgments with partners—within a small, highly autonomous team in a heavily regulated environment.

Location: London
Workplace: Hybrid
Employment Type: Full time
Job Function: Data Science & Machine Learning

Key Responsibilities

  • •Own a customer problem end to end: identify the opportunity, decide what should exist, build it, ship it, and learn from outcomes.
  • •Prototype and create complete customer experiences on the agentic platform using prompts, tools, and configuration rather than new services.
  • •Design evals that define what good looks like, use them for iteration, and drive release decisions.
  • •Work in the codebase: raise PRs for engineering review and partner with engineers for deeper technical work when needed.
  • •Shape agent behavior in production by balancing context, cost per conversation, latency, model choice, and routing, then improve based on real customer conversations.

Key Requirements

  • •You can point to AI-driven customer experiences you personally built and shipped, and explain your decisions.
  • •You understand how LLM systems work in practice, including context management, tool design, prompting, non-determinism, and trade-offs around cost and latency.
  • •You design evals and use them to find issues traditional testing would miss, informing iteration and release decisions.
  • •You think in systems and solve recurring problems at the underlying-cause level.
  • •You can make sound judgments on risk, compliance, and potential customer harm while building, partnering with Risk and Compliance.
