- LLMops (RAG, evals, fine-tuning, agentic workflows)
Proven track record deploying containerized services at scale (Docker, Kubernetes)
Clear communicator who bridges data science, product and engineering
Master's/PhD in ML, CS, Statistics or related
Passion for the craft of ML and deep learning: you love learning and keep up-to-date with the state of the art.
