Key Responsibilities: - Design and maintain AWS-based cloud infrastructure (Serverless + ECS microservices) - Migrate and optimize architecture from Lambda-heavy backend to hybrid (ECS + services) - Build and maintain CI/CD pipelines and infrastructure as code (Terraform) - Improve system scalability, reliability, and observability - Optimize MySQL/Aurora performance and infrastructure - Implement monitoring, alerting, and logging (Grafana, CloudWatch) - Work closely with backend team on performance and high-load architecture - Support multi-cloud integrations (AWS primary, some GCP & Azure)Tech Stack: - AWS (Lambda, ECS, EC2, S3, CloudFront, API Gateway, SQS, Kinesis, Aurora) - Terraform (Infrastructure as Code) - Grafana, CloudWatch (observability) - Serverless + ECS microservices architecture - MySQL / Aurora, Redis - CI/CD (GitHub Actions or similar) - Multi-cloud exposure (GCP, Azure — limited but used)Must-Have Experience: - 5+ years in DevOps / Cloud Engineering - Strong understanding of networking, security groups, load balancing - Strong AWS infrastructure experience (Serverless + containers) - Active use of AI tools (e.g. Copilot, Claude or similar) in daily development workflowNice-To-Have Experience: - Experience building high-load systems (1k+ RPS) - Experience with multi-region infrastructure
