Job
Description
As an Endpoint Software Developer, your role involves designing and building high-performance, low-overhead client software for Windows, macOS, and Linux environments. You will utilize your deep systems-level expertise and strong networking fundamentals to work with modern endpoint technologies such as eBPF, transparent proxies, and advanced packet inspection. Key Responsibilities: - Design, develop, and optimize endpoint agents for Windows, macOS, and Linux to monitor system behavior, enforce policies, and enable secure communication with backend services. - Leverage eBPF to create high-performance Linux endpoint components, including kernel-level monitoring, packet filtering, telemetry generation, and lightweight traffic inspection. - Implement robust networking features covering TCP/IP, SSL/TLS, HTTPS, SSE, WebSocket, and gRPC for secure and efficient data transfer. - Build and maintain transparent proxy components for intercepting, inspecting, and routing traffic without degrading system performance. - Perform deep packet inspection (DPI) to identify patterns, enforce rules, or extract relevant metadata for security or analytics purposes. - Implement and optimize load balancing and SSL handling mechanisms for reliability and scalability across diverse device types and environments. - Collaborate with platform, backend, and security teams to define data models, optimize communication flows, and integrate endpoint capabilities with cloud services. - Conduct rigorous profiling, optimization, and debugging at both kernel and user-space levels to ensure stability, reliability, and minimal resource consumption. - Maintain strong code quality through thorough documentation, automated testing, CI/CD integration, and adherence to secure development practices. Qualifications Required: - Strong proficiency in systems-level programming languages such as C/C++, Rust, or Go. - Deep experience in building Windows and macOS endpoint software, including drivers, services, background daemons, or low-level agents. - Hands-on expertise with Linux internals and knowledge in eBPF, XDP, or kernel networking subsystems. - Strong understanding of core networking protocols including TCP/IP, DNS, SSL/TLS, HTTPS, SSE, WebSocket, and gRPC. - Experience in traffic interception and inspection, DPI, and transparent proxy architectures. - Knowledge of load balancing algorithms, SSL offloading/termination, and certificate management. - Familiarity with sandboxing, endpoint security, or malware detection concepts. - Proficiency in performance profiling tools like perf, Wireshark, Sysinternals, and Instruments. - Experience in cross-platform development, including building installers, updaters, or system extensions. - Strong debugging skills, problem-solving capability, and attention to detail. In addition, the company prefers candidates with experience in endpoint security products (EDR/XDR/AV), virtual networking, TUN/TAP devices, user-space networking stacks, Zero Trust Networking, policy enforcement, identity-aware traffic routing, and cloud platforms (AWS/GCP/Azure) for agent-backend integrations.
