Application Programmer / Java Developer

This position supports Revolutional’s customer, Department of Homeland Security (DHS), where critical mission systems are undergoing modernization. The current environment consists of large, complex legacy systems that manage operational workflows (e.g., processing, tracking, and managing encounters). These systems have evolved over time and often include layers of business rules, manual processes, and tightly coupled functionality.

The core challenge is not simply rebuilding these systems; it is:

• Understanding how they actually work in practice
• Identifying which functionality is mission-critical
• Eliminating unnecessary complexity
• Translating that functionality into a modern platform-based architecture

As part of this effort, DHS is adopting Palantir as a target platform for modernization. Revolutional plays a key role in bridging legacy systems and this new platform, ensuring accurate translation of functionality while improving system design.

No prior Palantir experience is required. Revolutional will provide training and certification to enable engineers to build effectively within the platform., Revolutional is seeking a skilled Application Programmer / Java Developer to support a federal government client in a dynamic, agile development environment.
