Our products need to handle information at massive scale, and extend well beyond web search. We're looking for engineers who bring fresh ideas from all areas, including information retrieval, distributed computing, large-scale system design, networking and data storage, security, artificial intelligence, natural language processing, UI design and mobile; the list goes on and is growing every day. As a software engineer, you will work on a specific project critical to Google’s needs with opportunities to switch teams and projects as you and our fast-paced business grow and evolve. We need our engineers to be versatile, display leadership qualities and be enthusiastic to take on new problems across the full-stack as we continue to push technology forward.\nThe main mission is to improve the security of open-source software that Google and the world rely on.\nOpen source is now widely used not only by Google, but throughout the infrastructure of the modern world. Although open systems are easier to inspect, in practice the complexity is very high. Our team is here to help make fundamental changes to the processes used for open source development, so security is a key piece since the development from scratch.\nOur team works internally across Google and externally across the industry. The majority of our work is open source.\nThe Core team builds the technical foundation behind Google’s flagship products. We are owners and advocates for the underlying design elements, developer platforms, product components, and infrastructure at Google. These are the essential building blocks for excellent, safe, and coherent experiences for our users and drive the pace of innovation for every developer. We look across Google’s products to build central solutions, break down technical barriers and strengthen existing systems. As the Core team, we have a mandate and a unique opportunity to impact important technical decisions across the company.Responsibilities\nWrite and test product or system development code.\nParticipate in, or lead design reviews with peers and stakeholders to decide amongst available technologies.\nTriage product or system issues and debug/track/resolve by analyzing the sources of issues and the impact on hardware, network, or service operations and quality.\nSupport the vulnerability discovery and remediation platform for open source in Google and in the industry.\nFocus on designing and building infrastructure detecting, fixing and exposing potential risks and vulnerabilities in open source projects.\nQualifications\nMinimum qualifications:\nBachelor’s degree or equivalent practical experience.\n5 years of experience with software development in one or more programming languages.\n3 years of experience testing, maintaining, or launching software products, and 1 year of experience with software design and architecture.\n1 year of experience in building GenAI or agentic applications.\nPreferred qualifications:\nMaster's degree or PhD in Computer Science or a related technical field.\n5 years of experience with data structures and algorithms.\nExperience with open source software development.\nExperience with Cloud infrastructure and technologies.\nKnowledge of security engineering, computer, network security, authentication, security protocols.\nKnowledge of fuzzing, memory safety, vulnerability detection, disclosure and remediation","description_format":"text","description_chars":3556,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":true},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Advertising","Cloud
