  • Troubleshoot and resolve issues across the full software stack to support system reliability and availability.
  • Participate in system design and architecture discussions related to modularization, scalability, and observability.
  • Document system behaviors, edge cases, and changes to components to support internal knowledge sharing.
  • Work with cross-functional and distributed teams to translate business requirements into technical solutions.
  • Provide guidance to junior developers and monitor emerging technologies to suggest product and process improvements.

  • Familiarity with Git or similar version control systems.
  • Familiarity with both Linux and Windows.
  • Experience with Kubernetes and CI/CD pipelines using Azure DevOps.
