COBOL Mainframe
Developer
Pre-Apprenticeship

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.

The Problem

The COBOL
Talent Gap Is Real.

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.

R

Retiring Workforce, No Succession Plan

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.

M

Mission-Critical Infrastructure

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.

The Solution

Build the Pipeline.
From Scratch.

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.

Zero Recruitment Cost

Sourcing Costs Absorbed

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.

12-Month Apprenticeship

Evaluate Before You Commit

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.

Repeat Program

The Model Proved Itself

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.

Curriculum Overview

Zero to COBOL Developer.
