• Build, maintain, and troubleshoot GitLab CI/CD pipelines.

• Collaborate with team members on application architecture, implementation decisions, code reviews, and deployment practices.

• Support infrastructure-as-code efforts, especially where Terraform is used.

• Use IntelliJ IDEA as the primary development environment.

• Apply sound software engineering practices, including maintainable code design, testing, documentation, and operational awareness.

• Where appropriate, leverage AI-assisted coding tools to improve development productivity and code quality.

Required Qualifications

• Strong professional experience developing Java applications.

• Experience with Java 21 or recent versions of the Java SDK.

• Solid experience with Spring Boot and Spring-based application development.

  • Amazon ECS

  • Amazon API Gateway

  • Amazon DynamoDB

• Familiarity with Terraform or other infrastructure-as-code tools.

• Experience using IntelliJ IDEA in a professional development environment.

• Familiarity with AI-assisted development tools such as Claude Code, GitHub Copilot, Cursor, or similar tools.

• Experience troubleshooting cloud deployments, application logs, build pipelines, and environment-related issues.
