Help establish and enhance the Endevor-to-Git CI pipeline for RIO, including repository onboarding, source synchronization, Endevor compilation, automated quality checks, and security scanning using available enterprise capabilities.
Use GitHub Copilot responsibly in approved environments to assist with COBOL/JCL code understanding, impact analysis, documentation, code generation and refactoring, unit-test design, defect analysis, and knowledge transfer.
Validate all GitHub Copilot-generated or AI-assisted output through developer review, approved coding standards, testing, security controls, and established change-management processes.
Promote code explainability, dependency analysis, automated testing, modern debugging, reusable engineering patterns, technical-debt reduction, and measurable improvements to the mainframe developer experience.

Nice to have

Experience with Git, GitHub, branch and pull-request workflows, and CI/CD or DevSecOps practices.
Experience with Endevor Bridge for Git, Explorer for Endevor, VS Code, and Code4z/Zowe.
Experience using GitHub Copilot for legacy-code analysis, documentation, code assistance, test generation, defect analysis, or refactoring, with appropriate developer validation.
Exposure to automated code-quality and security scanning tools such as SonarQube and Veracode.
General knowledge of IBM MQ, SAS on z/OS, ACF2, and secure file-transfer or mailbox integrations.
Knowledge of registered investment products or processing
Experience with application ownership, audit/SOX evidence, technology risk, data retention, resiliency, and disaster-recovery activities.
