• Collaborate directly with founders and users to shape product roadmap.
• Design and implement LLM‑powered testing agents that explore, learn, and adapt in real time.
• Own the end‑to‑end stack, from Python back‑end services to TypeScript front‑end interfaces and cloud infrastructure.
• Run experiments on models, embeddings, and retrieval pipelines and move successful prototypes to production.

Required profile

• Demonstrated ability to ship product quickly in a high‑velocity, low‑safety‑net environment.
• Strong drive to execute, learn, and adapt faster than the problem evolves.
• Passion for AI/LLM technologies and a product‑outcome mindset.
• Comfort working across frontend, backend, and infrastructure without silos.
