An architect who can open an unfamiliar IBM i estate and make sense of it — the code, the designs behind it and the platform it runs on — and explain it clearly to the people deciding what happens next.

EXPERIENCE: 10–15 years
LEVEL: Senior Architect (hands-on)
PRACTICE: Midrange modernisation
LOCATION / TYPE: Chennai/NOIDA · Full-time / Consulting

THE ROLE
This is a comprehension and analysis role, not a greenfield build role. Our modernisation work starts with understanding what banks actually run today: large RPG and Synon / CA 2E application estates on AS/400 (IBM i), often thinly documented, with the original authors long gone. You will be the person who reads that code, reconstructs the design and platform architecture, and turns it into findings, documentation and recommendations that engineers, client architects and executives can act on — increasingly with AI-assisted analysis tools working alongside you.

WHAT YOU WILL DO
• Read and comprehend large RPG (RPG III / RPG/400, RPG IV / ILE, free-format) and CL code bases,



including Synon / CA 2E-generated programs and the 2E model behind them (functions, action diagrams, access paths, files).
• Reverse-engineer and document application designs: program flows, data models (DB2 for i, DDS, physical / logical files), batch and job streams, interfaces and integration points, and the business rules embedded in code.
• Analyse AS/400 architecture end to end — work management, subsystems, job scheduling, object / library model, security, journaling and commitment control — and assess fitness and risk.
• Produce estate assessments: inventory, dependency and impact analysis, complexity hotspots, dead code, modernisation options and recommendations, with explicit traceability back to source.
• Validate AI-assisted code-analysis and knowledge-extraction output against the real system, and feed corrections back to the platform team.
• Present findings to client architects, business stakeholders and leadership in plain lang
