  • Provision, monitor, and optimize cloud infrastructure for reliability, scalability, and performance
  • Support new product initiatives by deploying and managing microservices in Kubernetes environments
  • Design and manage infrastructure-as-code and deployment workflows using Terraform, Helm, and GitOps tools (e.g., Flux, ArgoCD)
  • Improve CI/CD pipelines and developer workflows using tools like CircleCI and GitHub Actions
  • Implement observability solutions (metrics, logging, alerting) to improve system visibility and operational response
  • Architect secure, cloud-native solutions across AWS, Azure, and/or GCP
  • Partner with engineering teams to deliver production-ready, compliant platform capabilities
What qualifications are necessary?

  • Experience with observability tools such as Datadog, Prometheus, or Grafana
  • Strong understanding of building reliable, scalable, high-performance systems
  • Ability to quickly learn new technologies and work independently in unfamiliar systems
  • A curious, self-directed mindset with strong problem-solving skills
Nice to Have
  • Experience with PKI, encryption, mTLS, or security-focused infrastructure
  • Familiarity with GitOps tools like Flux or ArgoCD
  • Experience integrating AI tooling (e.g., MCP servers) into production environments
  • Exposure to compliance-focused systems (PCI, SOC 2, ISO, etc.)
