About the job
The company 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 the company.
This position is fully remote and available to people residing in Colombia or Argentina with the right to work in that country.
Requirements
The ideal candidate will have 4+ years of professional COBOL development experience on IBM z/OS mainframes. Beyond that, we're looking for some of the following skills, but not necessarily all:
- 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, ChangeMan)
- 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.
Job Duties
- 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
