Job Description

Windows Application Developer (Kernel / Networking)

Our client is seeking a Windows Application Developer with deep expertise in Windows kernel-level programming, networking, and enterprise security. This role focuses on building native agents for Windows (and some macOS), leveraging WFP for firewalling, packet filtering, and enterprise VPN / ZeroTrust solutions. The ideal candidate is a true systems programmer who thrives in OS internals, networking stacks, and cross-platform agent development.

Key Responsibilities

  • Architect, develop, and maintain native Windows and macOS agents using platform APIs, kernel interfaces, and WFP.
  • Design and implement kernel-level networking solutions (firewalls, packet routing, VPNs, ZeroTrust).
  • Develop Windows drivers and system components with WDK / Win32 APIs; ensure code signing and driver certification.
  • Leverage BSD networking knowledge and macOS Network / System Extensions for packet filtering and routing.
  • Build cross-platform agent frameworks using Rust (40%) and Python (30%), with familiarity in Tauri / React UIs.
  • Debug production issues including kernel crashes, driver bugs, and network failures.
  • Implement observability stacks (Prometheus, Grafana, OpenTelemetry, ELK / Loki) for cross-platform monitoring.
  • Collaborate across teams to deliver secure, stable, and high-performance networking solutions.

Qualifications

  • 6–8+ years in systems programming with a strong focus on Windows internals.
  • Expertise in Windows Filtering Platform (WFP), Windows Driver Kit (WDK), Win32 APIs, and kernel networking.
  • Strong knowledge of IP networking, routing protocols, DPS, firewalls, and BSD networking stacks.
  • Proven experience shipping enterprise VPN, ZeroTrust, or endpoint security (XDR / MDR) solutions.
  • Advanced skills in C programming, with proficiency in Rust and Python for cross-platform agent work.
  • Familiarity with Tauri / React (front-end awareness, not a UI developer).
  • Hands-on debugging with tracers, profilers, crash dumps, and system performance tools.
  • Strong problem solver and constant learner with proven ability to ship modern, secure solutions.

    • Additional Info

  • Location : Dallas, TX
  • U.S. Citizen or Green Card Holder only.
  • Work split : ~30% kernel development, 40% Rust, 30% Python.
  • Interview Process : Recruiter screen → technical deep dive (kernel / networking) → peer panel.
