Legacy Modernization Engineer (IBM RPG & Synon)

For our client, we are looking for a Legacy Modernization Engineer (IBM RPG & Synon) to join their Core Clearing engineering team. This long-term initiative focuses on maintaining and modernizing a core clearing application originally built in 1991. You will start with business-as-usual (BAU) maintenance to master the domain and architecture before transitioning into an AI-assisted modernization program to transform ~10,000 Synon programs into a modern microservices architecture using IBM RPG (Full Free) and REST APIs.

What you’ll do

• Perform hands-on maintenance and feature updates on the current core clearing platform written in Synon/CA-2E.

• Architect and rewrite legacy logic into a microservices-based approach using IBM RPG (Full Free) and REST APIs.

• Leverage modern AI tooling to analyze, decompose, and accelerate the transformation of the legacy Synon codebase.

• Work with TD/OMS for change management and contribute to modern CI/CD practices on IBM Power Series hardware.

• Rapidly absorb complex domain knowledge around clearing, settlement, and financial markets to ensure smooth system transitions.

What we’re looking for

• 5+ years of hands-on experience with IBM RPG (Full Free).

• Proven track record developing and maintaining software using Synon/CA-2E.

• Solid experience building, consuming, and integrating REST APIs directly from RPG environments.

• Experience using TD/OMS and implementing CI/CD pipelines on IBM Power Series platforms.

• Experience with IceBreak.

• Domain knowledge of financial markets, clearing, or post-trade settlement processes.
