Senior Security Software Engineer, Linux Kernel Security - Nodes & Sensors

About Anthropic Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems. About the role Anthropic's Detection Platform team is building the next-generation Linux endpoint security system that protects our AI research and production infrastructure. We're looking for a senior engineer to architect and implement node-layer security sensors, develop kernel-based detection systems for ML workloads, and build tooling that leverages Claude to transform how security operations work. This is a high-ownership role on a small team. You'll design systems that run across our rapidly growing fleet with minimal performance overhead, partner closely with security and infrastructure engineers, and help shape the technical direction of endpoint detection at Anthropic. Key responsibilities - Build kernel-level security detections for our AI platform, including eBPF-based sensors for Linux endpoints - Design and implement scalable data pipelines for ingesting and processing security telemetry across our infrastructure - Architect monitoring solutions for production systems that minimize performance impact on ML workloads - Prototype new security tooling and analytics capabilities, including applications of Claude to detection and response workflows - Partner with security and infrastructure teams to translate requirements into reliable, maintainable systems - Contribute to the growth of the Security team through code reviews, mentorship, and hiring - Participate in an on-call rotation Minimum qualifications - Background in software engineering with a focus on security, infrastructure, Linux internals, and/or operating systems - Ability to write maintainable and secure code in Rust and/or C/C++ - Strong understanding of operating system internals and OS security primitives - Experience with test-driven development and CI/CD workflows - Experience partnering with security teams to translate requirements into technical solutions - Track record of leading technical projects with minimal guidance and bringing clarity to ambiguous problems Preferred qualifications - 7+ years of software engineering experience, with significant time spent on security, infrastructure, or operating systems work - Direct experience with eBPF and kernel-level instrumentation - Experience with detection-as-code workflows - Experience with infrastructure-as-code tools such as Terraform or CloudFormation - Background building security tooling from the ground up - Experience implementing security monitoring solutions (SIEM, log aggregation, EDR) - Background in detection engineering or security operations - Experience with SOAR platform or security automation development - Experience with data lake and database architecture, or query optimization over large datasets - Experience with API design and internal platform development - Track record of applying ML or AI to security problems - Experience scaling security operations in a high-growth environment - Experience contributing to hiring, mentorship, and engineering culture on a security team Logistics Minimum education: Bachelor’s degree or an equivalent combination of education, training, and/or experience Required field of study: A field relevant to the role as demonstrated through coursework, training, or professional experience Minimum years of experience: Years of experience required will correlate with the internal job level requirements for the position Location-based hybrid policy: Currently, we expect all staff to be in one of our offices at least 25% of the time. However, some roles may require more time in our offices. Visa sponsorship: We do sponsor visas! However, we aren't able to successfully sponsor visas for every role and every candidate. But if we make you an offer, we will make every reasonable effort to get you a visa, and we retain an immigration lawyer to help with this. We encourage you to apply even if you do not believe you meet every single qualification. Not all strong candidates will meet every single qualification as listed. Research shows that people who identify as being from underrepresented groups are more prone to experiencing imposter syndrome and doubting the strength of their candidacy, so we urge you not to exclude yourself prematurely and to submit an application if you're interested in this work. We think AI systems like the ones we're building have enormous social and ethical implications. We think this makes representation even more important, and we strive to include a range of diverse perspectives on our team. Your safety matters to us.
