About the Role

This role focuses on developing the Tetragon agent, enabling it for various embedded platforms and cloud environments, and creating eBPF programs to detect and prevent malicious activity. Tetragon is a Kubernetes-aware security tool leveraging eBPF for real-time observability and enforcement.

Responsibilities

• Develop high-quality Go (and eBPF) code for the Tetragon project
• Be a part of the Tetragon, Cilium, and eBPF OSS communities
• Design and implement advanced eBPF-based runtime security mechanisms for embedded, Kubernetes and VM environments
• Enhance and improve Tetragon's network parser capabilities
• Tackle challenging technical problems
• Participate in code reviews, architectural discussions, and contribute to technical documentation

Requirements

• 6+ years of experience in systems programming using C, Go or similar
• Experience in observability or security use cases: Linux systems programming, Linux kernel-level development, or eBPF development
• Prior experience in security hardening and defense techniques
• Prior experience in integrating or developing security frameworks for infrastructure-level products
• Prior experience in building control planes for security or similar
• Familiarity with CVE workflows, vulnerability data pipelines, or security event modeling
• Familiarity with Kubernetes and cloud-native environments
• Contributions to open-source security or networking projects (e.g., Tetragon, Cilium, Linux networking stack)
• Good communication skills, both written and verbal
