J2EE Developer (Legacy Modernization)

Remote

At IPT Associates (IPTA), we enjoy solving real-world problems with technology. We work closely with our customers, teammates, experts, and partners to come up with practical solutions that make a difference. Whether it's a government or business organization, we focus on understanding the need and building something that works.

Our Team

At IPTA, everything starts with our people. We're big believers that when you invest in your team, great things happen. That's why we encourage learning, growth, and trying new things-even if you don't have all the answers yet.

Our culture is rooted in fierce determination, fearless integrity, and passionate service-but we also like to keep things collaborative, supportive, and down-to-earth.

We're looking for people who:

• Are curious and excited about technology
• Like solving problems and figuring things out
• Can take initiative but also enjoy working with a team
• Want to keep learning, growing, and challenging themselves

If you're someone who's eager to jump in, learn something new, and make an impact-you'll fit right in here.

Responsibilities:

• Bridges the legacy system codebase and the Palantir Foundry migration team, reading, analyzing, and documenting existing application and data-integration logic so it can be mapped into the target data integration architecture's ETL pipelines
• Reverse-engineers and documents business rules embedded in the legacy application and data layers
• Supports static analysis of legacy ETL jobs
• Acts as SME liaison to the Foundry pipeline engineers, translating legacy transformation logic into terms they can re-implement correctly
• Documents application dependencies, including the database schema, integrations, and the NIPRNet/SIPRNet Data Guard replication path, to inform the eventual cutover and decommission plan
• Supports reconciliation testing by explaining why legacy output looks the way it does when it does not match the new Army Vantage (Foundry) output

Requirements:

• Bachelor's degree in Computer Science, Information Systems, or a related field (equivalent experience may be considered)
• 4+ years of professional Java/J2EE (Java EE) development experience
• Java/J2EE (Java EE) expertise: MVC Model 2 design patterns, DAOs, Servlets, JSP, EJB (session and message-driven beans), JDBC, JNDI, and JMS
• Oracle application and database logic development using PL/SQL (ideally Oracle Application Server and Oracle Database 19c)
• Oracle Data Integrator (ODI) and Oracle Cloud Infrastructure (OCI) Data Integration, including Oracle SQL and PL/SQL, ELT/ETL concepts, Oracle Data Transforms, and E-LT architectures
• Comfortable reverse-engineering undocumented legacy enterprise code with no SME available to explain it
• Working knowledge of ETL/batch processing concepts, such as daily/weekly sync jobs and materialized-view refresh patterns
• Create, modify, and test the code, forms, and script that allow computer applications to run. Work from specifications drawn up by software developers or other individuals
• Possesses and applies expertise on multiple complex work assignments. Assignments may be broad in nature, requiring originality and innovation in determining how to accomplish tasks
• Operates with appreciable latitude in developing methodology and presenting solutions to problems
• Contributes to deliverables and performance metrics where applicable
• An active Secret security clearance is required (role supports NIPRNet/SIPRNet work)

Preferred Qualifications:

• Prior exposure to Army force management or personnel systems (e.g., GFM DI, IPPS-A, TAADS); the domain-specific business rules are dense, and prior context shortens ramp-up considerably
• Experience on legacy-to-modern migration or decommission efforts, not just steady-state J2EE development
• Ability to collaborate closely with a Palantir Foundry team, communicating legacy logic in terms a Foundry engineer can act on (Foundry coding not required)
• Basic scripting (Python/shell) to build validation or bridge tooling between the two systems
• CompTIA Security+ or equivalent DoD 8570/8140 baseline certification
