• Provision cloud object storage for all application file storage needs, replacing local disk paths with an S3-backed solution.
• Set up CloudFront distributions for static frontend assets, replacing on-premises web server file serving.
• Implement infrastructure as code using Terraform, structured to support microservices decomposition.
• Establish observability: container metrics, structured logging pipelines, distributed tracing, and alerting dashboards.
• Implement security controls including network segmentation, WAF rules, encryption at rest and in transit, and least-privilege IAM roles.
• Participate in Agile/SCRUM processes, maintain infrastructure runbooks, and coordinate environment promotions and cutover planning.

Must-Have Qualifications

• 5+ years of DevOps / cloud infrastructure engineering with deep AWS hands-on experience.
• Proficiency with AWS ECS / Fargate, ECR, load balancing, VPC design, and IAM role configuration.

• Hands-on production experience with AWS RDS, Amazon MQ, S3, and CloudFront.
• Proficiency with infrastructure-as-code tools at enterprise scale, including AWS CDK with TypeScript, Terraform.
• Experience with container health checks, auto-scaling policies, rolling deployments, and blue/green strategies.
• Proficient in Git and familiar with Agile/SCRUM team processes.

Nice-to-Have Skills

• Experience with CloudWatch Container Insights and OpenTelemetry-based observability stacks.
• Familiarity with AWS DMS for coordinating minimal-downtime database migration cutovers.
• Experience with multi-environment promotion pipelines including manual approval gates.
• Experience with cloud cost optimization strategies for containerized and managed workloads.
• Experience with performance optimization and scalable cloud-native architectures.

We offer*:
