- Design interfaces for AI interactions: streaming responses, loading and error states, citations and confidence cues, and human-in-the-loop controls.

- Build APIs that expose fan behaviour analytics to the UI and to AI services.

- Use AI coding assistants in your daily workflow, and help the team shape good practice: prompting, code review of AI-generated code, testing and guardrails.

- Work closely with product and marketing to turn data into high-value features.

- Write clean, tested, maintainable code with accessibility and performance in mind.

- Strong React and TypeScript experience, including component architecture, state management, and performance.

- Hands-on experience using AI coding tools (Claude Code, Copilot or similar) in day-to-day development, with a clear view of their strengths and limits.

- CI/CD experience with Azure DevOps pipelines or GitHub Actions.

- Familiarity with LLM APIs (Anthropic, OpenAI, Azure OpenAI), prompt design, tool/function calling, or MCP.

- Experience implementing AI features in a UI: LLM-backed chat or copilots, generative UI, or AI-assisted search and filtering.

- Experience testing and evaluating non-deterministic features, and handling latency, cost, privacy and safety.

- Clear communication, including explaining blockers and timelines to non-technical stakeholders.

- Strong C# and experience building APIs in modern .NET (Core/6/8/10); awareness of .NET Framework migration considerations.
