We are looking for an exceptional Windows systems engineer with deep expertise in Windows kernel internals, operating system architecture, and endpoint technologies, who understands Windows below the Win32 API, from the NT kernel and executive subsystems to process lifetime management, memory internals, and modern platform security.
This is not an application development, framework engineering or WinAPI-only developer role.
You'll be designing and building the low-level endpoint infrastructure that powers real-time telemetry, behavioral detection, and system instrumentation across modern Windows environments.
You'll work across kernel-mode and user-mode, developing production-grade systems that operate reliably in highly concurrent, security-sensitive environments.
Design and develop production-quality Windows kernel drivers...
