# COBOL Developer (z/OS) - LATAM Remote

> Workstate · Colombia (Remote) · Contract · Posted 2026-10-06

**Workplace:** remote

## Description

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.

## 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
