Software Engineer Desktop Agent (C, C++, Linux, Windows, Network)

Our client is looking for an Software Engineer Desktop Agent. This role consists of designing, implementing, and optimizing 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.

Core Competencies:

• Advanced proficiency with Windows Driver Kit (WDK) for kernel-mode driver development
• Deep expertise in Windows Filtering Platform (WFP) for network packet filtering and inspection
• Strong knowledge of Win32 API and Windows system programming
• Understanding of Windows networking stack architecture and kernel networking components
• Experience with Windows security models, code signing, and driver certification processes
• Expertise in macOS/BSD networking stack including packet filter frameworks
• Proficiency with Network Extension and System Extension frameworks
• Understanding of macOS kernel architecture and XNU kernel development
• Experience with macOS security frameworks, entitlements, and system integrity protection
• Knowledge of macOS distribution and notarization requirements
• Advanced proficiency in Rust for system-level agent development and Python for backend integration
• Experience with Tauri/React for cross-platform user interface development
• Strong understanding of cross-platform build systems and deployment strategies
• Deep understanding of computer networking (TCP/IP, HTTP, DNS, routing protocols, firewalls, load balancing, security)
• Expertise in modern observability stacks (Prometheus, Grafana, OpenTelemetry, ELK/Loki) for cross-platform monitoring
• Performance analysis and troubleshooting using platform-specific tools (Windows Performance Toolkit, macOS Instruments, network analyzers)
• Debugging complex kernel-level issues using crash dumps, kernel debugging tools, and system tracing
• Experience with version control (Git), CI/CD systems (GitHub Actions, CircleCI), and ticket management (Jira, Azure DevOps)

Salary: $160,000 per year.

Benefits: Medical Insurance, PTO, 401 (k) and more.

The following section outlines our AI-assisted interview process and your rights as a candidate. 

AI-Assisted Interview Experience (Pete & Gabi – Rebecca):

To provide a consistent, fair, and flexible experience for all candidates, we use AI-assisted tools—including our proprietary platform Pete & Gabi – Rebecca—to support parts of the interview process. These tools help us:

• transcribe interviews,
• summarize candidate responses,
• generate job-related insights
• streamline communication and scheduling.

Please note that

• AI does NOT make hiring decisions.
• All decisions are made by our human recruiters, hiring managers, or client partners.
• The AI does not evaluate facial expressions, emotions, or physical traits.
• It is used only to support fairness, consistency, and efficiency.

If you prefer a non-AI interview format, we will gladly provide an alternative.

Technical or Case Interviews (Role-Dependent):

For certain positions, you may participate in:

• a technical interview
• a coding challenge
• a case study
• a client-specific assessment.

We will always explain what to expect in advance so you can prepare with confidence.

Human Review & Selection:

Every candidate’s profile—including interviews, conversations, and assessments—is reviewed by experienced recruiters and hiring leaders.

AI insights may assist with organization and evaluation, but final decisions are always human-driven.

Your Rights as a Candidate

At PTP, every candidate has the right to:

• Request a non-AI interview path
• Ask how your data is being used
• Request access to transcripts or interview recordings
• Request deletion of your AI-recorded interview
• Receive clear, timely communication

Our goal is to ensure you feel respected, informed, and supported throughout your experience
