EXFO Tech Stack

Network test, monitoring and analytics for telecom operators and hyperscalers

Telecommunications Québec, Québec 1,001–5,000 employees Founded 1985 Self-Owned

EXFO manufactures and sells hardware, software and services for testing and monitoring fixed and mobile networks. The stack is heavily weighted toward embedded systems (Vivado, Quartus, VHDL, ModelSim, Verilog simulation) and hardware validation, paired with Python scripting and enterprise infrastructure (SAP, Azure, Active Directory). Engineering hiring dominates the mix and accounts for roughly half of current openings — a signal that product development and field trial deployments (a recurring project theme) are the growth lever.
