Software Development Montréal, Québec 51–200 employees Founded 1992 Privately Held

SIGMA-HR operates a mature HR management platform serving 200+ companies across 20 countries, managing ~1 million employees total. The tech stack (C#, .NET, React, Angular, Vue, Blazor) reflects a modernization in flight: the company is actively migrating from ASP.NET Web Forms to .NET Core and Blazor, implementing observability practices, and rearchitecting the SaaS platform. Hiring leans sales-heavy (5 sales roles vs. 3 engineering) while recruiting for leadership gaps (development directors and team leads), suggesting a push to scale revenue alongside technical debt paydown.
