What you will do

• Design, build, and ship kernel- and user-mode components of the Linux Ent agent.
• Develop EDR detection and prevention through sensor instrumentation, event enrichment, correlation, and interception logic.
• Instrument Linux telemetry using eBPF, LSM, and audit subsystems across workstations, servers, containers, and cloud workloads.
• Harden the agent against tampering, bypass, evasion, unsafe input, and integrity failures.
• Keep CPU, memory, and I/O usage within strict budgets while processing thousands of events per second.
• Build automated regression coverage, resolve high-severity customer escalations, and collaborate with security research, AI, platform, and product teams.

• 10+ years designing, building, and delivering production C/C++ or Rust systems software, including substantial endpoint security, OS internals, or performance-critical native code experience.
• Deep knowledge of operating system internals, including process and thread lifecycle, memory management, file systems, drivers or kernel extensions, and IPC.
• Hands-on production experience with eBPF and experience building or operating EDR, EPP, XDR, AV, or equivalent detection-and-response products.
• Strong knowledge of attacker TTPs, low-level debugging, performance tracing, crash-dump analysis, and concurrent programming under load.
• Experience operating software across large fleets while maintaining stability and end-user performance.
• Fluency in Python or equivalent scripting for tooling and test automation, plus clear written and verbal communication.

Nice to have

• Production-scale kernel-mode driver or kernel extension development.
