About Qorsa Qorsa is a Canadian post-quantum cryptography and cybersecurity company building CasQade — a crypto-agile security platform protecting sovereign government, defence, financial, and critical-infrastructure networks against current and emerging cryptographic threats. We are headquartered in Waterloo, Ontario, with a European subsidiary in The Hague, Netherlands. Our work spans post-quantum cryptography, explainable AI, AI-driven threat intelligence, cryptographic agility, hardware security, and distributed systems, with active engagements across Canadian defence, NATO, and allied partner organizations. The Role We are hiring a DevOps Engineer to run the build, release and deployment infrastructure for CasQade, our crypto-agile post-quantum platform, and for our AI applications. Our components ship as container images and native Linux services, and customers run them in the cloud, on premises and on air-gapped networks. You will make our releases reproducible and our integration tests reliable, and build the deployment tooling our solutions team uses at customer sites. For a security company, how we build and ship software is part of what customers are trusting. Signed, reproducible, verifiable releases are central to the product, and you will own them.
