o CI/CD pipelines (GitHub Actions, GitLab CI, Jenkins, or similar)

o Logging, monitoring, and observability tools

o API gateways, reverse proxies, load balancing concepts

  • Experience with distributed systems, service discovery, and reliability patterns (circuit

breaker, retry logic).

Cloud Engineering (AWS Preferred)

o EKS, ECS, Lambda, API Gateway, S3

o RDS (Postgres), DynamoDB (optional)

o CloudWatch, IAM, Secrets Manager, Parameter Store

o VPC, networking fundamentals, security groups

  • End-to-end understanding of cloud deployment workflows, versioning, and release

management.

Quality & Engineering Excellence

  • Write high-quality, testable code and enforce engineering best practices.
  • Participate in code reviews, and technical discussions.
  • Drive improvements across performance, security, and automation.
