AWS (Must Have)

• AWS IoT Core, Lambda, API Gateway
• S3, DynamoDB, RDS / Aurora
• IAM, Cognito, CloudWatch
• VPC, networking fundamentals

Infrastructure & DevOps

• Terraform (required)

   – no manual console engineers.
• CI/CD pipelines with automated testing and deployments.
• Docker; Kubernetes is a plus (not mandatory).

IoT Domain Knowledge

• MQTT, device provisioning, device lifecycle management.
• Handling

  offline devices, retries, acknowledgements, and data loss prevention

  .
• Understanding of

  edge vs cloud responsibilities

  .

Experience Requirements
