  • Set up end-to-end observability: logs, metrics, traces, dashboards, and alerts using any one of the platforms including CloudWatch, OpenTelemetry, ELK or New Relic.
  • Diagnose and resolve production issues related to latency, throttling, auth failures, routing, certificates, and backend dependencies.
  • Build and maintain CI/CD pipelines and automation (GitHub Actions/Jenkins, Terraform/CloudFormation, Maven/npm) for repeatable deployments.

What We're looking for

  • Experience Required-5+ years in API
  • Strong hands-on experience with AWS API Gateway (REST API / HTTP API), stages, deployments, custom domains, throttling, caching, usage plans, and integrations.
  • OR strong hands-on experience with Apigee, including API proxies, policies, shared flows, environments, and deployments.
  • Strong understanding of REST API design and best practices; experience with OpenAPI (Swagger).
  • Solid experience implementing API security: OAuth2/OIDC, JWT, API keys, RBAC, mTLS, certificates, and integration with IdPs.
