- Review code and help maintain good engineering practices
- Improve application performance, database queries, and AWS costs
- Write tests to keep the code reliable and maintainable
- Monitor backend performance and fix issues proactively
- Set up proper error handling, logging, and alerts
- Support deployments, monitoring, and troubleshooting in production

- Experience with infrastructure-as-code tools such as Serverless Framework, AWS CDK, or Terraform
- Experience with Git, CI/CD, and modern deployment practices
- Experience writing backend tests and maintaining code quality
- Understanding of monitoring, logging, and observability tools such as CloudWatch or Datadog
- Strong problem-solving skills and the ability to work independently
- Available for 4–5 hours of overlap with US Eastern Time
