• Travel occasionally to Manassas, VA for integration and team collaboration.

Required Qualifications:

• At least 3 years of hands-on professional experience developing, maintaining, and enhancing production applications in Java and/or C++, with a strong emphasis on existing codebases.
• Experience working with service-oriented architecture (SOA) and enterprise integration patterns (e.g., SOAP services, XML/JSON messaging, WSDL, message queues) is highly desirable.
• Familiarity with modernizing or integrating existing systems, including refactoring, performance tuning, and incremental adoption of newer technologies or frameworks.
• Education:

Bachelor’s degree in Computer Science, Computer Engineering, or a related field that provides strong software development skills.
