COBOL Developer; z​/OS; LATAM Remote

Workstate seeks a COBOL Developer to join our team for an 18-month modernization project! In this role, you will convert a legacy RPG II codebase to COBOL on IBM z/OS in preparation for a cloud migration to Google Cloud Platform using the Raincode mainframe rehosting platform. You will work as part of a larger conversion team. If you are a solid COBOL engineer who enjoys working with data and takes pride in accurate, well-tested code, you'll fit right in at Workstate.

This position is fully remote and available to people residing in Colombia or Argentina with the right to work in that country.

• Strong SQL and data skills, especially DB2 for z/OS (embedded SQL, query tuning, data modeling)
• JCL, TSO/ISPF and batch processing
• VSAM, QSAM/sequential files and GDGs
• Mainframe utilities such as DFSORT/SYNCSORT and IDCAMS
• CICS
• Legacy modernization, code conversion or mainframe migration projects
• Mainframe rehosting or emulation platforms (Raincode, Micro Focus/Rocket Enterprise Server) or GCP
• Source control and change management tools (Git, Endevor, Change Man)
• Data validation, reconciliation and parallel-run testing
• B1 level (intermediate) or higher English: able to read and write technical documentation and take part in team discussions in English

You do not need RPG II experience. Engineers joining the project are trained on it.

• Convert legacy RPG II programs into well-structured, maintainable COBOL on z/OS
• Analyze existing program logic, file layouts and data flows to make sure the converted code behaves the same way
• Develop and maintain JCL, batch job streams and related utilities
• Write and tune SQL (DB2 for z/OS) and work with VSAM and sequential datasets
• Take part in unit, regression and parallel testing, including data validation and reconciliation between legacy and converted output
• Prepare code and data for rehosting on GCP with the Raincode compiler and runtime
• Document converted programs, data dependencies and technical decisions
• Work with the client's technical and migration teams in an Agile setting
