  • Automate environment provisioning using Infrastructure-as-Code (Terraform).
  • Implement and manage containerized workflows with Docker and Kubernetes (EKS or similar).
  • Collaborate with engineering teams to support deployments of C#, Python, and React-based applications.
  • Develop internal tooling for build automation, monitoring, logging, and performance optimization.
  • Improve release processes, reduce deployment friction, and increase system reliability.
  • Monitor environments using Datadog, CloudWatch, or equivalent observability tooling.

  • Scripting skills in Python.
  • Familiarity supporting C#/.NET Core, Python services, and React front-end builds.
  • Experience building secure, scalable, and highly available production environments.
  • Strong understanding of networking, monitoring, logging, and alerting frameworks.
