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 Full Stack Software Engineer to build the operator side of CasQade, our crypto-agile security platform. Customers use it to see and manage the security of their systems in real time.

You will work on the backend services and APIs behind the platform and the browser interface on top, alongside our platform and security engineers.

Our customers run sensitive networks, often fully offline. The interface has to be fast, clear and dependable for security and operations teams who rely on it to make decisions about their whole estate.

Responsibilities

- Build features in the operator interface, including onboarding, live status views and operator controls.
- Design and maintain versioned APIs used by the interface, our other services and customer automation.
- Build real-time views of activity across customer environments.




- Process incoming data from customer systems and store what operators need to search later.
- Integrate the interface with the rest of the platform’s services.
- Make sure the product runs on air-gapped networks with no external services or CDNs.
- Write unit and integration tests, and review other engineers’ code.
- Work with solutions architects on features customers ask for during deployments.

What We’re Looking For

- 3+ years building web applications, with production work on both the backend and the frontend.
- Solid experience in a backend language such as Go, Rust or Java.
- Solid JavaScript or TypeScript, HTML and CSS.
- Experience designing REST APIs and working with SQL databases.
- An understanding of TLS and certificate-based authentication from an application developer’s point of view.
- Experience building real-time features in the browser with WebSockets or server-sent events.
- Excellent communication skills and comfort working across disciplines.
- Eligibility for Government of Canada security clearance (Secret level).

Strong Assets

- Data visualization or mapping experience.
- Experience building tools for security or network operations teams.
- Familiarity with PKI and certificate lifecycle management.

Compensation

We compensate exceptionally well — a strong base salary plus meaningful stock options in a rapidly growing company.

Benefits

- Dental care
- Extended health care
- Vision care
- On-site parking

Work Location: In person, Waterloo, Ontario.
