DEFSEC Technologies Inc. Tech Stack

Tactical software and non-lethal systems for military digitization

Defense and Space Manufacturing Ottawa, Ontario 11–50 employees Founded 2017 Public Company

KWESST builds software and hardware for military command-and-control and non-lethal operations. The tech stack—Java, C#, .NET, Vue, Android—reflects a mature distributed systems approach, with SQLite and Liquibase suggesting offline-first tactical deployments where connectivity is unreliable. Current pain points (reliability, scalability, third-party integration, data accuracy) signal they're scaling from prototypes toward production systems at scale; active hiring velocity in Canada indicates execution against LC4ISR and land-command programs.
