Senior C++ Systems Engineer
About the Role

We are looking for a passionate and highly skilled Senior C++ Systems Engineer to join our core engineering team. In this role, you will be responsible for re-architecting and rebuilding our suite of cross-platform monitoring agents — currently written in C++ — to meet the demands of modern, high-performance, and scalable infrastructure environments.

You will work at the intersection of system-level programming, OS internals, and distributed agent design, ensuring our agents deliver reliable, low-overhead monitoring across Linux, macOS, Windows, and AIX platforms. If you live and breathe systems programming and get excited about pushing performance boundaries, this role is for you.
Key Responsibilities

Agent Re-Architecture & Development
- Lead the design and re-architecture of cross-platform C++ monitoring agents from the ground up, ensuring modularity, performance, and maintainability.
- Evaluate existing agent codebases, identify technical debt, and define migration strategies to modern C++ standards (C++17/20).
- Implement clean,



testable, and high-performance C++ code following established design patterns and SOLID principles.
- Collaborate with architecture and product teams to define agent feature roadmaps and technical specifications.

Filesystem Monitoring
- Design and implement filesystem monitoring components using platform-native APIs: inotify / fanotify (Linux), FSEvents / kqueue (macOS), ReadDirectoryChangesW (Windows), and AIX-specific equivalents.
- Develop productive file-change detection with minimal overhead, supporting real-time event streams for file create, modify, delete, rename, and permission change events.
- Handle edge cases such as deep directory watches, high-volume event bursts, and symbolic link traversal across platforms.

Process Monitoring
- Build robust process lifecycle monitoring using /proc (Linux), kinfo_proc / sysctl (macOS), toolhelp/PSAPI (Windows), and AIX process accounting API
