Mainframe Modernization Expert

Job Title: Mainframe Modernization Expert

Location: Columbia MD

Duration: Part-Time (20 hours/ week)

Job Description:

We are seeking an experienced Mainframe Modernization Expert with a solid track record in converting mainframe applications and databases to cloud-hosted modernized solutions. This role requires deep expertise in mainframe (M/F) systems hands-on experience with mainframe-to-modern code conversion tools and a strong understanding of cloud environments and Java-based solutions. The selected candidate will be responsible for analyzing designing and implementing migration strategies to transition our mainframe-based systems with minimal downtime and maximum data integrity.

Key Responsibilities:

• Analyze legacy mainframe systems (e.g. COBOL DB2 stored procedures BMS Maps JCL) to identify migration paths dependencies and potential risks.
• Migrate or redesign user interface components including BMS Maps into modern Java-based front-end frameworks.
• Translate and optimize batch processing components including JCL-driven jobs to Java batch frameworks ensuring equivalent functionality and performance.
• Design and execute a comprehensive migration strategy prioritizing critical components such as business logic UI screens batch processes and stored procedures.
• Utilize modernization and code conversion tools to facilitate an efficient migration process ensuring compatibility with modern cloud-hosted solutions.
• Convert or rewrite mainframe DB2 for z/OS stored procedures and schemas to Java-compatible formats or modern database solutions.
• Provide expertise in handling IBM Db2 for z/OS including schema understanding data model optimization and stored procedure integration with COBOL or other mainframe languages.
• Collaborate with cross-functional teams to maintain business continuity data integrity and minimize downtime during migration.
• Leverage cloud platform knowledge (e.g. AWS Azure Google Cloud) to deploy and manage modernized systems in cloud-hosted environments.
• Ensure all migrated applications UI components batch processes and databases are optimized and meet performance requirements in the cloud environment.

Key Qualifications:

• Mainframe and Database Expertise: Extensive experience with mainframe applications including BMS Maps JCL and DB2 and deep involvement in end-to-end migration processes.
• Modernization Tools Proficiency: Skilled in using code conversion and migration tools to support smooth and efficient transitions to modern architectures.
• Cloud Knowledge: Familiarity with cloud platforms such as AWS Azure or Google Cloud and deployment of Java-based solutions.
• DB2 for z/OS: Proficient in IBM Db2 for z/OS with strong knowledge of mainframe DB2 schemas stored procedures and experience rewriting them for modern databases.
• Java Understanding: Good knowledge of Java with familiarity in Spring or microservices-based frameworks preferred.

Abilities:

• Analyze and break down legacy components including BMS Maps batch JCL jobs and DB2 entities to define detailed migration strategies.
• Prioritize migration tasks to focus on critical system components and ensure minimal business disruption.
• Design and implement strategies that ensure data integrity maintain business continuity and deliver high performance in the modernized cloud environment.
