Full Job Description

📋 Description

• As an Endpoint Engineer (Linux) at Nightfall AI, you will lead the development of a production-grade, AI-native Data Loss Prevention (DLP) agent for Linux, building capabilities from the ground up to protect sensitive data across endpoint devices.
• You will design and develop kernel-level event interception mechanisms using eBPF, LSM hooks, netfilter, and fanotify, while building userspace components to enforce DLP policies in real time across Ubuntu, RHEL/CentOS, and other Linux distributions.
• You will collaborate with Mac and Windows endpoint teams to ensure cross-platform consistency in agent architecture, policy models, and DLP behaviors, owning features end-to-end from design to customer-facing documentation.
• You will diagnose and resolve complex systems-level issues such as kernel panics, race conditions, and IPC failures, ensuring agent reliability, upgrade safety, and minimal performance footprint in enterprise environments.

🎯 Requirements

• Expertise in C/C++ for Linux systems development; familiarity with Go is a strong plus.
• Demonstrable experience building production agents or system-level software on Linux.
• Deep hands-on experience with Linux kernel subsystems relevant to security and monitoring, including eBPF (BPF CO-RE, libbpf, BCC), LSM (SELinux/AppArmor), fanotify, inotify, netlink, and procfs.
• Experience with kernel-level debugging using tools such as ftrace, perf, crash, SystemTap, or GDB with KGDB.
• Ability to decompose complex business problems and own them end to end across teams.
• Minimum 5+ years of related systems/endpoint engineering experience.

🏖️ Benefits

• Opportunity to build a strategic new platform from the ground up at a fast-growing, AI-native cybersecurity company backed by top-tier VCs and industry leaders.
• Work alongside experienced Mac and Windows endpoint teams to shape cross-platform DLP agent architecture and enterprise security innovation.
• Exposure to cutting-edge technologies including eBPF, LSM, container runtimes, and enterprise deployment environments (MDM tools).
• Equal-opportunity employer committed to diversity, inclusion, and merit-based hiring with compensation tied to experience, skills, and market rate.
