Senior Security Software Developer Position Available

This is a general track for security-focused engineering in every team across all levels of seniority. Apply if you are already an exceptional security-focused software engineer.

Most product engineering teams include one or two spaces for dedicated security-oriented software engineers. Their role is to challenge the entire team to think more deeply about security. They contribute to the product as engineers too, but their primary focus is to improve security through state-of-the-art practices - from table-top threat model exercises to architecture reviews, from extended security testing with fuzzers and static analysis tools to external security analyst liaison.

We build a number of products that are entirely motivated by security technology and requirements, such as our AppArmor kernel investments and our hardening, compliance, and certification toolkits for Ubuntu.

As the publisher of Ubuntu we also handle long-term security response and hardening for the entire operating system and open-source universe. 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.

These roles encompass all aspects of product security, including feature development, vulnerability response, proactive security, and open-source community participation. All security roles interact closely with many of the other Canonical engineering and development teams, customers, and partners across the open-source community.
