• Assist with production implementations, post-deployment validation, troubleshooting, and remediation efforts.
• Communicate technical findings, risks, recommendations, and project updates to both technical and non-technical stakeholders.

Required Qualifications

• Bachelor's degree in Computer Science, Information Systems, Business Information Systems, or a closely related field.
• Minimum of 3 years of progressively responsible IT experience involving systems analysis, application support, requirements documentation, data analysis, SQL development, application development, or related technical work.
• Hands‑on COBOL experience is required, including experience analyzing, supporting, troubleshooting, or working with COBOL‑based applications in a mainframe or legacy environment.
• Strong Systems Analyst experience, including requirements gathering, functional analysis, process analysis, technical documentation, stakeholder coordination, testing, and implementation support.
