The mainframe runs the global financial system. Trillions of transactions per day. And the workforce that built it is retiring. KTCS partnered with a Fortune 500 Financial Services company to solve the succession problem recruiting 8 non-traditional candidates, training them from zero to COBOL developer in a matter of weeks, and converting every single one to full-time employment at zero recruitment cost to the employer.
COBOL remains the backbone of global financial services infrastructure. An estimated 95 billion lines of COBOL code are still active worldwide, processing more transactions daily than any other technology stack. The engineers who wrote and maintain that code are retiring — and there is no pipeline to replace them.
Most Fortune 500 financial services companies face the same problem: their most senior COBOL engineers are approaching retirement age, and the university pipeline stopped producing COBOL graduates decades ago. The talent gap is structural, not cyclical.
The mainframe runs payroll, banking transactions, insurance claims, and government benefits for hundreds of millions of people. Maintaining and extending that infrastructure requires specialists — and the specialists are disappearing.
KTCS designed a COBOL Mainframe Developer Pre-Apprenticeship from the ground up — a curriculum that takes candidates with zero COBOL experience and builds them into production-ready mainframe developers. The employer defined the technical requirements. KTCS designed, and delivered.
The employer paid nothing to recruit these 8 developers. KTCS and its specialty staffing partner handled candidate sourcing, screening, and selection — identifying aptitude for logical thinking and precision over COBOL credentials that did not exist in the market.
The DOL Registered Apprenticeship model allows employers to observe apprentice performance across a full year before converting to full-time employment. Every one of the 8 apprentices in this cohort earned that conversion — 100% conversion rate, zero early departures.
The success of this 2022-2023 cohort led directly to a second, larger COBOL program in 2024-2025 — this time placing 15 apprentices across two Fortune-ranked employers simultaneously. See the COBOL Dual Placement program.
The COBOL Mainframe Developer curriculum was developed in collaboration with the Fortune 500 Financial Services employer to align with their specific mainframe environment, coding standards, and production deployment requirements. Candidates enter with no COBOL experience and exit production-ready.
If your organization runs on COBOL and your senior engineers are approaching retirement, KTCS can build your next generation of mainframe developers from non-traditional talent — with documented outcomes, $0 recruitment cost, and a DOL Registered Apprenticeship structure that lets you evaluate talent before committing to full-time hires.
