Senior Mainframe Engineer (COBOL/CICS/DB2)

Senior Mainframe Engineer (COBOL/CICS/DB2)

This role focuses on the ongoing maintenance and support of core mainframe applications. You will be responsible for managing complex legacy logic, researching system behaviors, and ensuring the stability of brokerage platforms. While the primary focus is on mainframe technologies, a foundational understanding of cloud environments is required to support long-term modernization efforts. You are expected to independently review designs, ask critical questions, and challenge technical approaches to ensure optimal system performance.

Core Responsibilities

• Application Maintenance: Maintain and optimize existing mainframe applications, focusing on COBOL, CICS (online and batch), and JCL environments.
• Logic & Event Analysis: Research and review existing mainframe logic to determine how events behave and document findings for technical stakeholders.
• Database Management: Manage data and execute complex queries using DB2 and SQL.
• Independent Research: Independently analyze system behaviors and conduct thorough design reviews to identify potential improvements or risks.
• Collaborative Development: Partner closely with developers to refine technical stories and requirements within an Agile environment. Ability to understand API driven cloud applications and collaborate with modernization teams.
• Debugging & Troubleshooting: Perform end-to-end analysis and debugging of production issues, including the ability to look deeply into system logs.
• AI Integration: Use Copilot and other AI-assisted tools to facilitate code research, analysis, and maintenance tasks.

Top Required Skills

• Mainframe Tech Stack: Deep expertise in COBOL, CICS, DB2, and JCL.
• Domain Knowledge: Professional experience in the BFSI sector, specifically within Brokerage, corporate actions, Trade Settlement, or loan origination.
• Data & SQL: Strong understanding of DB2; knowledge of Oracle, SQL or other distributed databases is highly preferred.
• Cloud & Modernization Basics: Foundational knowledge of cloud platforms (AWS) and distributed systems to assist with potential modernization transitions.
• Agile Tools: Proficiency in Jira for task tracking and project management.
• Distributed Architecture: Understanding of REST APIs and the basic functionality of distributed web applications.

Professional Qualities

• Analytical Mindset: Strong ability to perform root-cause analysis and end-to-end system reviews.
• Communication & context switching: As these roles might be required to work on multiple things they should be able to communicate proactively and context switch.
• Challenger Mentality: Proactive in asking questions and challenging existing designs to ensure quality and efficiency.
• Self-Directed: Ability to research complex, undocumented logic and provide independent technical assessments.
