Required Skills & Experience
  • Experience: 15+ years of IT experience, with a proven track record of leading technical architecture for large-scale legacy core platform transformations (COBOL to Java migrations preferred).
  • Domain Expertise: Strong foundational knowledge in Capital Markets or Financial Services (Direct Investment Accounting platform experience is highly advantageous).
  • Technical Depth: * Deep expertise in Java Full-Stack architecture, microservices design, and building high-throughput transactional APIs.
    • Strong capability to read, interpret, and deconstruct COBOL logic and Sybase relational databases/stored procedures.
  • AI & Engineering Methodology: * Hands-on familiarity or strong conceptual mastery of integrating autonomous AI coding agents (Devin, Blitzy) or advanced AI developer environments into the enterprise SDLC.
    • Familiarity with Specification-Driven Development methodologies to align legacy specs with AI outputs.
  • Team Dynamics: Proven experience steering large-scale projects using a heavily leveraged global delivery model.
Key Responsibilities
  • Migration Strategy & Governance: Define the blueprints, data mapping, and pattern-matching strategies to migrate millions of lines of COBOL and Sybase stored procedures to Java microservices with zero business logic deviation.
  • AI-Assisted SDLC Orchestration: Establish and optimize the development pipeline to leverage autonomous AI software engineering agents (Devin, Blitzy) for automated code generation, refactoring, and unit testing.
  • Target Architecture Design: Design a high-performance, scalable target Java architecture leveraging modern API/Microservices and Photon patterns tailored for high-volume financial transactions.
  • Functional Parity Verification: Define automated testing and dual-run validation frameworks to cross-check legacy system outputs against the new Java platform, guaranteeing 100% data and logic alignment.
  • Technical Leadership & Pod Governance: Serve as the onsite technical anchor for 5 global delivery PODs (80:20 offshore/onsite model), conducting architecture reviews and unblocking technical dependencies between legacy logic and modern code.
