Job Specifications
This is a general track for security-focused engineering in every team at Canonical, across all levels of seniority. Apply here if you are already an exceptional security-focused software engineer.
Most product engineering teams at Canonical 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 also 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, Canonical customers and our partners across the open source community.
Location: We have open roles for security specialist software engineers in every timezone.
What you'll do
Security roles might tackle any of the following:
Define, implement and document new security features
Lead security-oriented thinking in a product engineering team
Analyze, fix, and test vulnerabilities in Canonical and open source Software
Contribute to Ubuntu and upstream projects to benefit the community
Audit and analyze source code for vulnerabilities
Integrate new tools in our security infrastructure, pipelines and processes
Achieve and retain various security certifications
Extend and enhance Linux cryptographic components - specifically with modules such as OpenSSL/Libgcrypt - with the features and functionality required for country-specific compliance such as FIPS and CC certification
Work with external partners to develop CIS benchmarks
Design and develop hardening automation for Ubuntu
Monitor the security industry for new developments
Develop, test and maintain new software capabilities
Provide guidance and support to other engineering teams
What we are looking for in you
An exceptional academic track record from both high school and university
Undergraduate degree in Computer Science or STEM, or a compelling narrative about your alternative path
Drive and a track record of going above-and-beyond expectations
A thorough understanding of the common categories of security vulnerabilities
Modern engineering techniques to find and fix them
Familiarity with open source development tools and methodologies
Skill in one or more of C, Python, Go, Rust, Java, Ruby or PHP
Experience as a security champion
Experience driving security within a wider SDLC process
Professional written and spoken English
Experience with Linux (Debian or Ubuntu preferred)
Excellent interpersonal skills, curiosity, flexibility, and accountability
Passion, thoughtfulness, and self-motivation
Excellent communication and presentation skills
Result-oriented, with a personal drive to meet commitments
Ability to travel twice a year, for company events up to two weeks each
Optional skills we also value
