Here's a closer look at this key role:Design, implement, and optimize robust cross-platform agents for Windows and macOS environments, focusing on kernel-level networking, system extensions, and low-level system integration. Leverage deep expertise in Windows and macOS kernel development, networking stacks, and system-level programming to deliver secure, high-performance agents that seamlessly integrate with operating system networking and security frameworks.
Responsibilities- Architect, develop, and maintain native agents for Windows and macOS platforms, utilizing platform-specific APIs and kernel interfaces.
- Design and implement kernel-level networking solutions using Windows Filtering Platform (WFP) and macOS Network Extensions.
- Develop Windows drivers and system components using the Windows Driver Kit (WDK) and Win32 APIs.
- Create and maintain macOS system extensions and leverage BSD networking stack capabilities including packet filter frameworks.
- Build cross-platform agent frameworks using Rust and Python with Tauri/React-based user interfaces.
- Analyze and optimize network performance by understanding Windows and macOS kernel networking decisions and packet routing.
- Implement and maintain observability stacks (metrics, logs, events, traces) for cross-platform agent monitoring and debugging.
- Debug complex production issues involving kernel-level interactions, driver behavior, and system extension functionality.
- Collaborate with other engineers to deliver seamless cross-platform features and maintain API contracts for the ControlOne platform.
- Ensure security and compliance best practices are embedded throughout the agent lifecycle, including code signing and platform security requirements.
- Automate build, deployment, and testing workflows for multi-platform agent distribution using CI/CD pipelines.
- Write clear, maintainable documentation for kernel-level development and contribute to operational excellence across Windows and macOS environments.
