Sr. Engineer 2 - Sensor, Core Windows (Remote)

Role overview Build core Windows system software for an endpoint security sensor that monitors activity, helps prevent malicious behavior, and sends telemetry for analysis. The role owns capabilities across kernel and user mode, including work touching major operating system subsystems and memory management. Reliability, performance, and correctness matter because this software runs on protected endpoints at scale.

Responsibilities - Design, develop, and own Windows sensor components from technical design through delivery and production validation. - Contribute to architecture and technical direction for endpoint detection and response capabilities. - Coordinate with Linux and macOS engineers on features that share cross-platform components. - Lead or contribute to design and code reviews, helping maintain a high engineering standard. - Investigate production issues and customer escalations, including crashes, hangs, and performance regressions. - Improve test infrastructure and tooling for kernel-mode software, and mentor other engineers.

Requirements - Deep experience with C or C++ and Windows kernel or driver development. - Knowledge of Windows internals, including processes, threads, memory management, and I/O systems. - Ability to reason about low-level system behavior, performance, and stability under real-world workloads. - Experience designing, implementing, and supporting production software through validation and issue resolution. - Strong collaboration skills for working across engineering teams and functions.
