Meet the Team Isovalent, now part of Cisco, is the company founded by the creators of Cilium and eBPF. Cisco Isovalent builds open-source software and enterprise solutions solving networking, security, and observability needs for modern cloud native infrastructure. The flagship technologies, Cilium and Tetragon, are the choice of numerous, industry-leading, global organizations. We believe in fostering an inclusive workplace where every team member feels valued, respected, and empowered. We believe that every employee contributes to our success, and we are committed to fostering an environment where everyone can thrive. We encourage candidates from all backgrounds to apply and join us in our mission to deliver exceptional products and services. Your Impact Tetragon is a flexible, Kubernetes-aware observability and security tool that delivers real-time insights and enforcement. Leveraging the power of eBPF, Tetragon provides low-overhead, in-kernel visibility and intelligence across diverse environments. As a Technical Leader, you will be at the forefront of advancing Tetragonu2019s capabilities. You will guide architectural direction while staying deeply engaged in building the systems that power our platform. Your impact will span designing high-performance data pipelines, optimizing database and distributed system performance, and ensuring massive streams of system events can be ingested, aggregated, and distilled into meaningful intelligence. You will collaborate closely with teams across Cisco, including Hypershield and Splunk, to create the integration points that transform raw data into actionable insights for enterprise security. In this role, youu2019ll solve some of the most complex system-level challenges in observability and infrastructure, helping Tetragon evolve to meet the needs of modern cloud-native environments. What youu2019ll do: Develop high-quality Go (andeBPF) code for the Tetragon project. Design and implement new Tetragon features toenhanceits capabilities for Runtime security detection and enforcement Design andoptimizesystems for large-scaleTetragondeployment and operation in K8s or VM platforms Architect infrastructure that converts raw event data into intelligence streams with minimal performance overhead. Contribute to open-source projects and represent CiscoIsovalentin community discussions. Participate in architecture reviews, code reviews, and documentation. Minimum Qualifications Bachelors 8 years of related experience, or Masters 6 years of related experience, or PhD 3 years of related experience 10 years of experience in systems programming (Go,C,or similar; Tetragon is primarily written in Go).
