• Set up service mesh (Istio) for traffic management, mutual TLS, and observability dashboards in Grafana.
• Collaborate with DevOps to integrate ArgoCD for progressive delivery and blue‑green deployments.
• Document API contracts using OpenAPI and enforce versioning policies across the platform.

Must-have skills

• Deep experience designing and scaling microservice architectures on AWS or GCP.
• Proficiency with Docker, Kubernetes, Helm, and service mesh technologies.

• Hands‑on knowledge of CI/CD tools (GitLab CI, Jenkins) and infrastructure as code (Terraform).
• Ability to mentor teams on best practices for automated testing and monitoring.

Nice to have

• Familiarity with serverless functions (AWS Lambda) for edge processing.
• Experience with chaos engineering tools such as Gremlin.
