You are familiar with Kubernetes beyond the basics - you can write a Helm chart for a new service with relative ease, you understand best practices around security, and you have prior job experience or certifications to prove this. You have worked with relational databases before - we use PostgreSQL, but we are not particularly picky about this one as long as you have a solid grasp on the fundamentals. You have worked at a startup before - you understand that things don’t always go according to plan, that there is significant technical debt, that some tasks just need to be done, and that sometimes there are no processes or documentation to guide your hand. You are not afraid of taking a task from start to finish - gathering requirements, figuring out and implementing the best technical solution, then deploying and monitoring the results. You have worked at least 3 years on systems at scale. Who You Might Be (nice-to-haves) You understand how Kafka works - maybe you even worked with Redpanda before.  You know what a JWT token is, and how OpenID Connect and SAML work. Maybe you even heard about Keycloak, or have worked on authentication systems before. You have done IaC deployments with Argo CD or Terraform, or have used Google Cloud Platform and Google Kubernetes Engine before. You have experience with Grafana’s observability stack - Prometheus, Tempo and all the rest. You might have even written a PromQL query for a new alert once or twice. You are familiar with FlatBuffers and Protocol Buffers, have written or consumed gRPC services before, and can design simple RESTful APIs.
