C++ Software Developer – Endpoint Security Windows

Role overview Develop and maintain Windows components for an endpoint security product used across a large installed base. The work spans new capabilities and a mature codebase where performance, reliability, security, and compatibility matter. You’ll work close to the operating system, investigate difficult issues from real deployments, and coordinate with engineers building related security technologies.

Responsibilities - Design, implement, and improve C++ services, processes, libraries, and other Windows components. - Integrate security capabilities developed by other engineering teams. - Use Windows APIs and system-level features to build product functionality. - Diagnose crashes, hangs, memory issues, performance regressions, concurrency problems, and interactions between components. - Use debugging and diagnostic tools such as Visual Studio, WinDbg, ETW, and Windows Performance Analyzer to investigate issues. - Contribute to architecture discussions, code reviews, testing practices, and collaboration with QA and product teams.

Requirements - Strong production experience with C++, modern C++, and the C++ Standard Library. - Experience building software for Windows and familiarity with the Win32 API. - Understanding of object-oriented design, algorithms, data structures, memory management, multithreading, synchronization, and inter-process communication. - Knowledge of operating system concepts, including processes, threads, virtual memory, services, files, I/O, and resource behavior. - Strong troubleshooting skills, including methodical investigation of problems that are hard to reproduce. - Basic understanding of networking and common protocols, plus clear communication and cross-team collaboration skills.

Nice to have Experience with Windows internals, crash dump analysis, ETW and performance tools, kernel or driver development, Windows networking or filtering, cybersecurity, TLS and cryptography, deployment and updating, performance optimization, Python or PowerShell, Rust, or long-lived products with strict compatibility needs.
