You aren't just a developer; you are the primary technical steward of a highly critical public sector application. For 30 years, this custom-built HR/Payroll suite has served as the operational backbone for a major provincial entity, ensuring everyone is paid accurately and on time. We are looking for a veteran who respects that legacy and has the vision to lead it into the future - all from the comfort of your own home office anywhere in Canada.
...
This is a rare "Bridge" role. From a fully remote environment, you will maintain the deep, foundational logic of a Unisys OS2200 architecture while simultaneously architecting its evolution through Azure DevOps and modern CI/CD practices.
You are a master of the "old ways" - ECL scripting, Demand processing, and RDMS databases but you don't live in the past. You are highly proficient with AB Suite (LINC) System Modeler and are ready to integrate legacy configurations into Visual Studio and automated build pipelines.
As the Mainframe SME, you will lead the transition from legacy LINC to AB Suite, staying current with modern enterprise tools while leveraging your deep mainframe expertise. You’ll be the key person who translates 1980s-era logic into 2026-era efficiency. It's a niche, "unicorn" skillset, and we treat it as such.
Who You Are:
A veteran of the Unisys ecosystem with deep LINC/AB Suite development experience.
Someone who understands that "mission-critical" isn't just a buzzword - it's a commitment to high-availability systems.
A technician based anywhere in Canada who finds the bridge between legacy infrastructure and modern DevOps to be an exciting technical puzzle, not a chore.

Responsibilities
Technical Lead: Manage the end-to-end generation and deployment cycles for AB Suite (formerly LINC) runtimes on the OS2200 platform.
