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.
EXFO is a Canadian telecom equipment and software vendor founded in 1985, now operating at 1,001–5,000 employees across 10 countries. They serve fixed and mobile network operators, hyperscalers, and hardware manufacturers with specialized test platforms, monitoring solutions, and analytics tooling for 5G, fiber-optic and cloud-native network transformations. Core specialties span wireline and wireless testing, optical protocols (SONET, SDH, OTN), carrier Ethernet, and high-speed interfaces (40G/100G). Product portfolio includes the FTB platform, RTU firmware testing products, and emerging capabilities in photonic integrated circuit inspection. Go-to-market combines direct sales and field-led proof-of-concept deployments.
EXFO uses VHDL, Vivado, Quartus, ModelSim and cocotb for hardware design and simulation; Python, Perl, TCL, C and C++ for software; SAP for ERP; Azure, Azure DevOps and Active Directory for cloud and identity infrastructure; and VMware, Linux, Windows Server and CentOS for virtualization and systems.
Active projects include FTB platform development, new product introduction (NPI) initiatives, high-speed electrical interface validation, RTU firmware testing, field network and Ethernet-IP testing products, photonic integrated circuit inspection, and prototype-to-production transitions for demo equipment deployments.
