Software Development Mont-Saint-Guibert 501–1,000 employees Founded 1995 Privately Held

OpenWay operates Way4, a mature digital payments software stack built on Java, Oracle, and Linux for on-premise, cloud, and hybrid deployment. The hiring mix is heavily weighted toward support (70% of active roles) with sparse engineering capacity, which aligns with their operational model: the product is stable and widely deployed, but field implementation and compliance upgrades dominate project workload. Infrastructure scaling and database performance appear to be persistent operational bottlenecks.
