• Experience with LLM application quality, evaluations, scaling prompt engineering, and optimizing latency and costs of agent loops.

• Knowledge of OAuth 2.0 / OIDC and multi-tenant authorization design.

• In-depth understanding of EKS, GKE, or AKS internals.

• Contributions to Kubernetes or cloud-native open-source software.

• Must reside in one of the specified European countries.
