  • Comfortable navigating ambiguity and translating business goals into clear technical plans and deliverables
  • Excited by large, complex problems and motivated to continuously improve foundational systems

    • What We Use
  • Our infrastructure runs primarily in Kubernetes hosted in AWS’s EKS
  • Infrastructure tooling includes Istio, Datadog, Terraform, CloudFlare, and Helm
  • Our backend is Java / Spring Boot microservices, built with Gradle, coupled with things like DynamoDB, AirFlow, Postgres, and Redis, hosted via AWS
