About the role

Key responsibilities & impact

Build internal tools and coach-facing features on top of LLMs (Claude, OpenAI, open-source models)
Turn unstructured conversational data (WhatsApp threads, coaching notes) into structured, reliable signal
Design and maintain prompt chains, RAG pipelines, and agent workflows where they genuinely help
Prototype rapidly, going from idea to working demo in days
Evaluate model outputs, set up evals, and iterate on quality, with a focus on accuracy coaches can trust
Wire AI into our existing systems (platform APIs, databases, WhatsApp, Slack)
Own the full stack of what you ship: frontend, backend, model integration, deployment
Sit with coaches regularly. Watch how they work. Build for their reality, not for a spec
