Software Systems Engineer (SE)

Job Summary:

We are seeking an Software Systems Engineer (SE) to implement solution based on contract requirements to meet the needed Proof of Concept (PoC) objectives. 

The Mechanization of Contract Administration Services (MOCAS) system, originally developed in 1958, remains the Department of Defense’s primary platform for contract administration, entitlement, and disbursing. Managing approximately 51% of procurement spending and over 90% of payments for complex contracts, MOCAS is a mission-critical system supporting military services, defense agencies, and contractors within the Defense Industrial Base. However, the system relies on aging mainframe technology, including COBOL, Assembler Machine Language, and hierarchical databases, making sustainment increasingly difficult due to technological obsolescence and a shrinking pool of skilled personnel. To address these challenges, Diné Source is leading a Critical Stabilization (CS) effort aimed at modernizing the system while maintaining operational continuity. Leveraging our decades of experience supporting mainframe systems coupled with established and emerging code conversion practices and advanced AI-powered frameworks, Diné Source will automate the conversion of legacy code into maintainable, future-ready languages, enhance system security, and transition to scalable architectures. This initiative ensures that MOCAS continues to fulfill its essential mission, safeguarding the Department’s contract administration and payment functions while laying the groundwork for future technological advancements.
