Full Stack Java Developer

Agensys is seeking a Full Stack Java / AI Software Developer to support a new initiative focused on expanding cloud-based flight planning and automation capabilities.

This effort is part of a broader flight service modernization initiative and will involve approximately six months of intensive product development before transitioning into operations and maintenance. The new Alaska capability is expected to eventually integrate with existing flight service systems supporting the continental United States.

The development team will use modern full-stack technologies and AI-assisted software engineering tools to accelerate the delivery of new application capabilities.

What Makes This Opportunity Different

The team is adopting an AI-driven development model where engineers use Claude and AI coding agents to perform a significant portion of the coding work.

Developers will be responsible for understanding requirements, designing technical solutions, breaking down development activities, and providing detailed instructions to AI agents. They will then review, test, troubleshoot, and refine the generated code to ensure it meets production requirements., * Design, develop, test, and maintain full-stack Java applications supporting FAA flight planning and automation capabilities.

• Develop backend services using Java, Spring Framework, and Spring Boot.
• Develop frontend components using React, JavaScript, HTML, and CSS.
• Design and integrate RESTful APIs and supporting application services.
• Use Claude and AI coding agents to accelerate development, debugging, testing, and implementation.
• Translate technical requirements into structured development plans and detailed instructions for AI coding tools.
• Direct AI agents to generate application functionality and assist with software engineering tasks.
• Review, troubleshoot, test, and refine AI-generated code.
• Develop and execute unit and functional tests using tools such as JUnit and Mockito.
• Apply secure coding principles and maintain high standards for application performance and reliability.
• Use GitLab for source control, code reviews, collaboration, and development workflows.
• Participate in Agile ceremonies, including sprint planning, daily stand-ups, backlog refinement, and technical design discussions.
• Collaborate with product owners, software engineers, systems engineers, and DevSecOps teams.
• Develop and support cloud-based and containerized applications.
• Troubleshoot defects and resolve technical issues throughout development and testing.
• Support integration with existing FAA flight service systems.
• Assist with transitioning new capabilities into ongoing operations and maintenance.
