Our platform, Ubuntu, is widely used in breakthrough enterprise initiatives such as public cloud, data science, AI, engineering innovation, and IoT. Our customers include the world's leading public cloud and silicon providers, and industry leaders in many sectors. 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.\nThe company is founder-led, profitable, and growing.\nCanonical is looking for exceptional security-focused software engineers to be integrated across product teams. While they also 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. \nThese roles encompass all aspects of product security, including feature development, vulnerability response, proactive security, and open source community participation. Engineers in these roles collaborate closely with other Canonical teams, customers, and partners across the open source ecosystem.\nEach product engineering team at Canonical reserves one or two openings for security-oriented software engineers. We also develop a number of products driven entirely by security needs, such as our AppArmor kernel investments and the Ubuntu Security Guide (USG). As the publisher of Ubuntu, we also 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.\nApply here if you are an exceptional security-focused software engineer, passionate about open source, and excited by Canonical's products and mission.\nThis role requires the ability to be productive in a globally distributed team through strong self-discipline and motivation. It also involves mandatory international travel at least twice a year, typically for one week.\nLocation: Worldwide, this is a globally remote role\nWhat you'll do\nSecurity roles might tackle any of the following:\nDefine, implement, and document new security features \nLead security-focused initiatives within a product engineering team\nAnalyze, fix, and test vulnerabilities in open source software\nContribute to Ubuntu and upstream open source projects to benefit the community \nAudit and analyze source code for vulnerabilities \nIntegrate new tools into our security infrastructure, pipelines, and processes\nAchieve and retain various security certifications \nExtend and enhance Linux cryptographic components to meet country-specific compliance requirements, such as FIPS and Common Criteria (CC) certifications\nWork with external partners to develop Center for Internet Security (CIS) benchmarks\nDesign and develop hardening automation for Ubuntu \nStay up to date with trends and developments in the security industry\nDevelop, test, and maintain new software capabilities \nProvide guidance and support to other engineering teams on security best practices\nWhat we are looking for in you\nAn exceptional academic track record from both high school and university\nUndergraduate degree in Computer Science or STEM, or a compelling narrative about your alternative path\nA track record of going above and beyond expectations\nThorough understanding of the common categories of security vulnerabilities and how to fix them\nKnowledge of modern software engineering techniques\nFamiliarity with open source development tools and methodologies \nSkill in one or more of C, C++, Python, Go, Rust, Java, Ruby, PHP, or JavaScript/Typescript\nExperience as a security champion\nExperience driving security within a wider SSDLC process \nProfessional written and spoken English \nExperience with Linux (Debian or Ubuntu preferred) \nExcellent interpersonal skills, curiosity, flexibility, and accountability \nPassion, thoughtfulness, and self-motivation \nExcellent communication and presentation skills \nResults-oriented, with a personal drive to meet commitments \nOptional skills we also value\nClear and effective communication with both the team and Ubuntu community members\nExperience working with the Linux kernel \nExperience with security certifications and knowledge of FIPS and/or Common Criteria (CC)\nExperience with OVAL (Open Vulnerability Assessment Language) \nKnowledge of cryptographic modules such as OpenSSL and Libgcrypt\nKnowledge of low-level Linux cryptography APIs\nDemonstrated ability to learn quickly\nPerformance engineering experience \nWhat we offer you\nWe consider geographical location, experience, and performance in shaping compensation worldwide. We revisit compensation annually (and more often for graduates and associates) to ensure we recognize outstanding performance. In addition to base pay, we offer a performance-driven annual bonus. We provide all team members with additional benefits, which reflect our values and ideals. We balance our programs to meet local needs and ensure fairness globally.\nDistributed work environment with twice-yearly team sprints in person\nPersonal learning and development budget of USD 2,000 per year\nAnnual compensation review\nRecognition rewards\nAnnual holiday leave\nMaternity and paternity leave\nEmployee Assistance Programme\nOpportunity to travel to new locations to meet colleagues\nPriority Pass, and travel upgrades for long haul company events\nAbout Canonical\nCanonical is a pioneering tech firm at the forefront of the global move to open source.
