• Provide time and effort estimates for assigned work items and small enhancements; assist on estimates for moderate projects.
• Actively participate in Agile ceremonies (stand‑ups, planning, reviews, retros).
• Document tickets, decisions, and work acceptance in team tools.
• Mentor peers informally on standards and procedures as needed (no formal people leadership).

Mainframe Application Developer Experience: 5+ years of mainframe development in enterprise settings (or equivalent).

• Proficient in COBOL (maintenance and net‑new development).
• Proficient in Natural (maintenance and net‑new development).
• Strong working knowledge of JCL (batch authoring, scheduling handoff, troubleshooting).
• Experience with ADABAS and DB2 (queries, data analysis, understanding of performance basics).
• Familiarity with Oracle concepts and SQL tooling (e.g., PL/SQL Developer or equivalent).
• Comfortable with tools such as QMF, Visio (or equivalents) for data and design work.

• Detail-oriented, organized, and dependable follow‑through.

Preferred Qualifications: Experience with Natural/ADABAS in public sector or large enterprise environments. Exposure to mainframe CI/CD and change tools (e.g., Endevor, ChangeMan, ISPW).
