Security Software Engineer — Container Network Security

Employment: Full-time Experience level: Mid-Senior Level Job Description We are looking for a security programmer to help us build the next generation AI container network security system. This role sits at the intersection of systems programming, network security, and cloud-native infrastructure. What You'll Do Help design and implement traffic inspection and prevention components that run in-line within Kubernetes clusters (as a DaemonSet, sidecar, or CNI-integrated component) Build or contribute to protocol parsers and signature/rule-matching engines Contribute to an AI-assisted signature generation pipeline Work with the Linux networking stack to intercept and act on traffic with acceptable latency overhead Help ensure the data path is efficient enough to run under the resource budgets typical of Kubernetes workloads Collaborate with detection research and cloud security teams to translate threat intelligence into enforceable rules and behaviors Qualifications Professional experience in Rust or C/C++ (comfort with both, or willingness to pick up the second, is a plus — not a hard requirement) Security background - experience with developing security products - such as IPS, firewall, researcher, API security, etc General familiarity with Kubernetes and at least one public cloud (AWS, Azure, or GCP) — production experience is preferred, but strong infrastructure/networking experience elsewhere is also welcome Comfort working on systems/infrastructure-level software rather than purely application-level code Hands on AI SDLC experience Curious Tech savvy Good communication skills Independent Advantage Experience with DPI engines, protocol parsers, or signature-matching systems (e.g., Snort/Suricata-style rules) Exposure to ML/AI approaches for anomaly detection, classification, or rule generation Linux kernel/networking internals: netfilter/nftables, eBPF/XDP, TCP/IP, TLS Kubernetes networking specifics: CNI, NetworkPolicy, service mesh data planes (Envoy/Istio) Container runtime/isolation experience: containerd/CRI-O, namespaces/cgroups Low-latency/high-throughput systems experience (zero-copy design, lock-free structures) Familiarity with attacker techniques and IPS/IDS evasion Comfort with ambiguous, greenfield technical work     Company Description At Check Point, what you do matters.
