Senior Security Software Engineer

Secure Software Development Opportunities

Canonical is a leading provider of open source software and operating systems to the global enterprise and technology markets. Our platform, Ubuntu, is widely used in breakthrough enterprise initiatives such as public cloud, data science, AI, engineering innovation, and IoT.

The company is a pioneer of global distributed collaboration, with 1200+ colleagues in 75+ countries and very few office-based roles. Teams meet two to four times yearly in person, in interesting locations around the world, to align on strategy and execution.

Canonical is seeking exceptional security-focused software engineers to join our product teams. While they contribute to the product as engineers, their primary focus is to challenge the entire team to think more deeply about security through state-of-the-art practices such as threat modeling, table-top exercises, architecture and design reviews, static analysis tools, and fuzzing, among others.

These roles encompass all aspects of product security, including feature development, vulnerability response, proactive security, and open source community participation. Engineers collaborate closely with other Canonical teams, customers, and partners across the open source ecosystem.

We also develop products driven entirely by security needs, such as our AppArmor kernel investments and the Ubuntu Security Guide (USG). As the publisher of Ubuntu, we handle long-term security response for the entire operating system and open source ecosystem. Working with tens of thousands of upstreams means that we need to be fluent in every major programming language and design, build, and adopt sophisticated tools that enable us to work at scale and speed with confidence.

This role requires strong self-discipline and motivation, as well as mandatory international travel at least twice a year.

Location: Worldwide, this is a globally remote role
