Kainos Tech Stack

Enterprise systems integrator and Workday implementation specialist

IT Services and IT Consulting Belfast 1,001–5,000 employees Founded 1986 Public Company

Kainos is a public enterprise systems integrator operating across digital services and Workday implementations for healthcare, commercial, and public-sector clients. The tech stack reflects dual operating modes: a polyglot engineering layer (Java, Python, Node.js, Scala) paired with deep Workday tooling (Workday Studio, Workday payroll expertise), now aggressively adopting GitHub Copilot, Copilot Studio, and AIOps. Hiring is decelerating but remains engineering-heavy (229 roles), with notable velocity in senior and lead positions—signaling focus on delivery quality and scaling existing engagements rather than market expansion.
