Mainframe Developer/Programmer Analyst, Level 3

We are seeking a Mainframe Developer role in Texas for a long-term contract.

Perform advanced automated systems development work as a member of the project team to implement the four standardized NASWA SIDES exchanges: Additional Fact-Finding, Determinations, Monetary Charges, and Benefit Charges. Responsible for activities during all phases of the system development life cycle including external customer service, analyzing and documenting requirements, coding, testing as well as resolving software, data, hardware and reporting problems and troubleshooting system issues for internal and external clients. Develops and tests COBOL, Natural and JCL Applications to meet design specifications. Documents current processes, creates and reviews project specification modifications, and creates test cases for testing the new and modified programs. Analyze, document, design, and develop logical, structured programs and systems appropriate to customer needs that may be maintained by others. Test applications in accordance with agency standards. Ensure adherence to programming documentation and procedural standards, and management goals and objectives. Perform other duties as assigned to support the NASWA SIDES initiatives. Integrate the incoming and outgoing NASWA SIDES exchange data streams into the existing core legacy processing architecture. This initiative requires comprehensive systems analysis and modification of current runtime routines, user interface screens, database tables, and batch processing jobs. Because data formats, triggers, and validation rules vary across functional areas, a separate, dedicated analysis phase must be executed independently for each of the four SIDES Exchanges (Additional Fact-Finding, Determinations, Monetary Charges, and Benefit Charges). Perform other duties as assigned.
