Job Description:
Mainframe systems are at the heart of the digital economy, with 80% of the world's structured corporate data residing or originating on mainframes, and 55% of all enterprise applications hitting the mainframe to complete transactions. Our industry-leading software solutions are critical to many Fortune 1000 companies.
We are seeking a hands-on, highly skilled principal engineer to own, maintain, and expand our enterprise COBOL application. Unlike traditional legacy production systems, this specific platform is a critical internal-only tool used to generate test data, simulate complex business scenarios, and support demo environments across Broadcom's mainframe software division.
In this role, you will be the absolute authority on this system. You will act as a "player-coach"-getting your hands dirty in the mainframe codebase while simultaneously serving as the main subject matter expert (SME) to advise our division on COBOL integration, modernization, and testing strategies.
Key Responsibilities
Own the Roadmap:Define, prioritize, and manage the backlog for the COBOL application, ensuring it meets the evolving needs of our QA, automation, and demo teams.
Balance "Run" vs. "Build":Decide when to patch existing logic and when to engineer new, scalable capabilities to support modern testing frameworks.
Code & Implement: Write, test, and deploy COBOL code to add new features and enhance the application's capabilities.
Use What We Build: Leverage products from the MSD DevOps solution to analyze, build, debug, manage, and validate the applications.
Environment Support:Ensure the applications remain stable, reliable, and integrated with our modern CI/CD pipelines and middleware.
Internal Consultant:Act as the go-to technical advisor for other product teams needing to build test environments and demo scenarios using the applications.
Governance:Establish a process for community contributions from multiple internal organizations.
Required Technical and Professional Expertise
12+ years of hands-on software engineering experience, with a heavy focus on enterprise COBOL development within IBM mainframe or mainframe-emulation environments.
Bachelors and 12+ years of related experience; or Masters degree and 10+ years of related experience
High proficiency in building applications that leverage mainframe subsystems (Db2, IMS, CICS, IDMS, Datacom)
Experience leading technical initiatives across multiple teams and stakeholders
Experience using Source Code Management tools such as Endevor and GitHub.
Soft Skills & Professional Competencies
Strong written and verbal communication skills; ability to deliver succinct technical presentations and write clear documentation for diverse stakeholders.
Excellent problem-solving, structural debugging, and data-driven analysis capabilities.
High emotional intelligence, a hunger for learning emerging technologies, and the capacity to give and receive constructive feedback.

Ability to work independently and in a team-oriented environment.
Open to learning new technologies and programming languages.
