Build kernel-facing agents, PAM modules, privileged services, authentication and authorization workflows, systemd services, and Linux packages. Troubleshoot low-level security and execution issues involving permissions, SELinux, AppArmor, and race conditions. Collaborate with engineering and QA teams on architecture, testing, production support, and cross-platform functionality while using AI-assisted development tools. The summary above was generated by AI, As a Senior Linux Systems Engineer on Keeper's PAM team, you will design and build security-sensitive components that control privileged execution and elevation on Linux endpoints. This is a systems engineering role focused on endpoint privilege management, process authorization, Linux security boundaries and long-running privileged services. You will work across a Rust-based Linux agent, native C PAM modules and .NET services running on Linux. The role requires strong knowledge of Linux internals and the ability to reason carefully about process identity, permissions, authentication, kernel-facing APIs and secure failure behavior. This is not a traditional application development role; the work operates close to the Linux operating system and directly influences how privileged processes are authorized and executed., * Design, develop and maintain Linux endpoint privilege management capabilities across Rust, C and .NET components * Build and enhance kernel-facing agent functionality using Linux interfaces such as fanotify, the proc filesystem, namespaces, capabilities and process identity * Develop and maintain native PAM modules and Linux privilege-elevation workflows * Build long-running privileged Linux services using Rust, Tokio, MQTT, TLS and asynchronous programming patterns * Develop Linux-specific orchestration and session-management capabilities in .NET 8, including process authentication, access controls, ephemeral accounts and session monitoring * Diagnose complex Linux execution and security issues involving blocked processes, authentication races, permissions, SELinux, AppArmor and system service behavior * Design secure privilege-enforcement mechanisms based on least privilege, process trust and protection against time-of-check/time-of-use (TOCTOU) and authorization race conditions * Build and maintain systemd services, RPM and DEB packages, installation workflows, service hardening and operational diagnostics * Collaborate with PAM, endpoint, QA and platform engineers on architecture, testing, cross-platform functionality and production troubleshooting * Use AI-assisted development tools such as Claude, ChatGPT, GitHub Copilot or similar platforms to improve systems research, debugging, code development, testing and technical documentation, This notice explains how Keeper Security processes your personal data during recruitment.
