Hands on Cloud Dev Ops / Microservices Engineer to design, build, and operate secure, scalable, and observable cloud native platforms and services. You’ll own CI/CD, container orchestration, infrastructure as code, and runtime reliability for microservices partnering closely with software engineering, security, SRE, and product teams to deliver high quality releases with speed and confidence.

• Design, provision, and maintain cloud infrastructure (AWS, Azure) including compute, networking, storage, IAM, and managed services.
• Implement Infrastructure as Code (IaC) with Terraform, Cloud Formation, ARM, Bicep; enforce Git Ops practices (pull requests, code reviews, change history).
• Build multi-account subscription landing zones, network segmentation, and controls for cost, security, and compliance.
• Optimize cloud spend with right sizing, autoscaling, reserved savings plans, and cost governance dashboards.
• Build robust CI/CD pipelines (Azure Dev Ops, Git Hub Actions, Jenkins, Git Lab CI) with automated build, test, security scans, artifact management, and progressive delivery (blue-green, canary).
• Standardize pipelines as reusable templates, implement trunk-based development, and robust branching strategies.
• Enable automated rollbacks and deployment health checks; integrate quality gates (unit, integration, contract tests).
• Containerize services (Docker) and operate them on Kubernetes (AKS, EKS, GKE) or Open Shift.
• Manage service discovery, ingress, service mesh (Istio, Linkerd), config and secret management, HPA, pod disruption budgets, and node pools.
• Implement microservices best practices (circuit breakers, retries/backoff, idempotency, API gateways, rate limits, event driven patterns such as SQS, SNS, Kafka, Event Hub, Pub Sub).
• Establish end-to-end observability: metrics, logs, traces with Prometheus, Grafana, Cloud Watch, Azure Monitor, ELK, Splunk, Open Telemetry.
• Define and track SLI, SLO, SLA; create actionable alerts and on-call runbooks; participate in incident response and post-incident reviews (RCA).
• Conduct load performance testing; remediate hotspots at infrastructure, container, and application layers.
