  • Support smaller web applications using Thymeleaf, HTML, CSS, and JavaScript.

  • Work with AWS-based infrastructure and services, including ECS, API Gateway, and DynamoDB.

  • Contribute to source control and development workflows using GitLab.

  • 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 applications with Java.

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

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

  • Experience designing, building, and consuming REST APIs.

  • Strong working knowledge of JSON and API integration patterns.

  • Familiarity with front-end technologies including HTML, CSS, and JavaScript.

  • Experience using Git-based source control, preferably GitLab.

  • Experience working with CI/CD pipelines, preferably GitLab CI/CD.

  • Practical experience developing, deploying, or supporting applications in AWS.

  • Ability to work independently, communicate clearly, and deliver high-quality work in a contractor capacity.

Preferred Qualifications

  • Experience with Thymeleaf for server-side templating.

  • Hands-on experience with AWS services such as:

    • 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.

  • Understanding of secure coding practices and cloud application security concepts.

Technical Environment

Our current technology stack includes:

  • Java SDK 21

  • Spring Boot / Spring Framework

  • Thymeleaf

  • REST APIs

  • JSON

  • HTML / CSS / JavaScript

  • AWS, including ECS, API Gateway, and DynamoDB
