OverviewDecisionPoint Corporation is seeking a Mid-Level Software Developer 6 Java Backend to support our U.S. Transportation Command (USTRANSCOM) Integrated Booking System (IBS) program. This role is primarily focused on the development, enhancement, and sustainment of Java-based backend applications and services that support mission-critical transportation and logistics operations.
The Software Developer will design and develop backend services, APIs, integrations, and application components using Java and modern Java frameworks such as Spring Boot. The developer will work across the software development lifecycle, supporting new capabilities, system enhancements, defect resolution, integration, testing, and deployment.

- Integrate backend services with relational databases, external systems, and other application components
- Translate functional and technical requirements into reliable, scalable, and maintainable software solutions
- Write clean, efficient, testable, and maintainable Java code following established coding standards and software engineering best practices
- Develop and maintain unit and integration tests to support application quality and reliability
- Participate in peer code reviews and incorporate feedback to continuously improve code quality
- Troubleshoot and resolve backend application defects, integration issues, and performance problems
- Analyze application logs and system behavior to identify root causes and implement effective solutions
- Support application integrations across system components and external interfaces
- Contribute to CI/CD pipelines and automated build, test, and deployment processes
- Ensure applications comply with DoD security requirements, secure coding practices, and applicable STIG requirements
- Participate in Agile development activities, including sprint planning, daily stand-ups, backlog refinement, demonstrations, and retrospectives
- Develop and maintain technical documentation for application components, APIs, integrations, and system changes
- Collaborate with senior developers, technical leads, QA, DevSecOps, database, infrastructure, and other engineering teams to support successful releases and deployments
