  • All our services run in Kubernetes.
  • We are in the process of switching away from our Ruby monolith to a brand-new microservice architecture.
  • Domain-driven design is at the heart of our development process, we like to build fast but think about the bounded context before we start.

  • Knowledge of event-driven systems and tools/protocols like Kafka, and gRPC will be a plus.
  • Have experience (~3+ years) working on internal product engineering teams, developer tools, developer productivity or infrastructure products at scale.
  • Are a generalist engineer with an ability to pick up new frameworks quickly and willing to work across the stack.
