Job description

Senior/Lead CA Gen Engineer – Mainframe Modernization

Overview

We’re seeking a Senior or Lead CA Gen Engineer to join an established team of 15–20 engineers on a large-scale mainframe modernization initiative. This role is ideal for someone with deep expertise in CA Gen (Broadcom Gen / COOL:Gen) and COBOL who can reverse-engineer legacy applications and help drive their migration to modern technologies, including Java and .NET.

You’ll analyze existing CA Gen models, runtime frameworks, and generated COBOL code to uncover underlying business logic and translate it into detailed technical specifications for replacement systems. Your work will play a key role in reducing dependency on legacy CA Gen and mainframe technology.

This is a fully remote opportunity with no on-call responsibilities. Both Senior and Lead-level candidates will be considered.

Key Responsibilities

• Analyze CA Gen models, runtime frameworks, and generated COBOL code to understand legacy application behavior and business rules.

• Reverse-engineer existing applications and translate their functionality into detailed technical specifications for modern replacement systems.

• Support modernization efforts focused on transitioning legacy CA Gen/mainframe applications to platforms such as Java and .NET.

• Collaborate with architects, developers, and other engineers to validate migration approaches and ensure business logic is accurately preserved.

• Identify technical risks, dependencies, gaps, and edge cases within legacy applications.

• Document legacy architecture, application workflows, data flows, and system dependencies.

• Contribute to knowledge-sharing efforts, helping the team understand complex CA Gen models and COBOL implementations.

Required Qualifications

• 5+ years of hands-on experience with CA Gen (Broadcom Gen / COOL:Gen), including its models, runtime framework, and underlying application structure.

• 5+ years of COBOL development experience.

• Strong understanding of CA Gen-generated COBOL code and the ability to interpret complex legacy application logic.

• Experience with mainframe modernization, application migration, or legacy system transformation.

• Ability to translate reverse-engineered business logic into clear, detailed specifications that guide the development of replacement applications.

• Strong analytical and problem-solving skills, particularly when working with complex legacy codebases.

• Excellent communication skills and the ability to collaborate effectively across technical teams.

Nice to Have

• Hands-on experience modernizing CA Gen applications to Java and/or .NET.

• Experience with CICS, Db2, VSAM, or IMS DB.

• Familiarity with Java or C# development.

• Familiarity with AWS or cloud-based application architectures.
