Job Title: Technical Business Analyst (AS400 / SICS)
Location: Singapore (onsite)
Experience: 8+ years
Role type: Contract

Role Overview
We are seeking experienced Technical Business Analysts with strong AS400 expertise to support a major core banking migration program. This role focuses on analysing the existing AS400-based systems, performing reverse engineering, and producing detailed technical and functional documentation to support the transition to a new COTS platform.
This is a business–technical hybrid role with no hands-on development, but deep technical understanding of AS400 applications, file structures, and integrations is essential.

Key Responsibilities

• Analyse the existing AS400 environment, including applications, programs, data models, database structures, and system workflows.
• Perform reverse engineering of legacy AS400 components to understand current functionality, logic, and dependencies.
• Document AS400 system behaviour, process flows, file mappings, data mappings, integration points, and business rules.
• Work closely with architects, product teams, and vendor teams involved in the migration to a COTS platform.
• Review legacy jobs, CL programs, RPG logic (read-only), file definitions, and batch processes to capture functional and technical details.
• Translate technical findings into clear, structured documentation for migration and development teams.
• Participate in walkthroughs, requirement clarification sessions, and solution discussions to ensure accurate understanding of the current system.
• Support gap analysis, impact assessment, and mapping of legacy functionalities to new COTS product capabilities.
• Act as a bridge between business, technology, vendor teams, and migration specialists.
• Ensure documentation quality and completeness to support seamless knowledge transfer.

Must-Have Skills & Experience

• 8+ years of experience working with AS400 technologies (CL, RPG, DB2/400 concepts, job scheduling, file structures).
• Strong experience analysing AS400-based applications in financial services or banking environments.
• Proven capability in reverse engineering legacy systems and producing detailed documentation such as:
  • File mappings
  • Data flow diagrams
  • Functional flows
  • Technical specifications
  • Interface documentation
• Ability to interpret AS400 components without performing actual development.
• Strong understanding of core banking processes, batch jobs, data models, and system dependencies.
• Excellent analytical thinking, problem-solving, and communication skills.
• Ability to work independently and manage ambiguity typical in migration projects.

Good-to-Have Skills

• Knowledge or experience with SICS (Silverlake Integrated Card System).
• Experience working on core banking migration projects (legacy-to-COTS).
• Understanding of cards systems, payments, or transaction processing.
• Exposure to vendor-driven implementations (Temenos, Silverlake, Finastra, etc.).
