Responsibilities
- Build features in the operator interface, including onboarding, live status views and operator controls

- 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

- Strong 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
