Job Title: Senior COBOL Developer – Mainframe Decommission
Location: Freeport, ME (On-site)
Employment Type: Contract (W2 through ZipStaff)

About the Opportunity

ZipStaff is seeking a Senior COBOL Developer to support a mainframe decommission initiative within the Marketing technology landscape of a leading retail organization.

The focus of this role is to move, improve, or remove existing mainframe workloads as the organization modernizes off the mainframe. Ideal candidates bring strong COBOL/mainframe depth plus practical cloud skills to help migrate and improve applications rather than simply maintain legacy code.

What You’ll Do:

Analyze existing COBOL / mainframe applications supporting Marketing processes.
Support decommission planning by identifying workloads to migrate, improve, or retire.
Design and implement changes required to move functionality off the mainframe.
Improve or remediate COBOL applications where they must remain temporarily in production.
Partner with application, architecture, and business stakeholders to ensure Marketing capabilities are preserved during transition.
Contribute to modernization work that leverages cloud platforms where appropriate.
Document current-state logic, interfaces, and target-state recommendations.

Required Qualifications:

7–8+ years of hands-on COBOL / mainframe development experience.
Proven experience supporting mainframe application maintenance, enhancement, or decommission/migration work.
Ability to analyze complex legacy programs and determine whether to move, improve, or remove functionality.
Strong troubleshooting, analysis, and documentation skills.
Ability to work on-site in Freeport, ME.
Must be legally authorized to work in the United States without sponsorship now or in the future.

Preferred Qualifications:

Hands-on cloud experience (AWS, Azure, or GCP) used in support of mainframe modernization or application migration.
Experience with Marketing, customer, or retail systems on the mainframe.
Familiarity with related mainframe technologies (JCL, CICS, DB2, VSAM, or similar).
Prior experience on a mainframe exit / modernization program.

About ZipStaff

ZipStaff partners with leading organizations to connect skilled technology professionals with high-impact contract opportunities. We focus on quality matches and long-term success.

To apply, please submit your resume highlighting your COBOL/mainframe experience and any cloud or modernization work.
