Sr. Product Security Engineer, Network and Infrastructure

CrowdStrike CrowdStrike · Enterprise · United States · Remote

CrowdStrike is seeking a Sr. Product Security Engineer to focus on network security for their AI-native platform. The role involves architecting and engineering network security solutions across hybrid environments (public cloud and data centers), identifying security gaps, and leading cross-functional initiatives. Responsibilities include designing network segmentation, building monitoring and automation, leading threat modeling, and mentoring other engineers. The ideal candidate has deep networking expertise, strong protocol knowledge, experience in SaaS environments, and automation skills.

What you'd actually do

  1. Develop and maintain a comprehensive understanding of CrowdStrike's hybrid networks spanning public cloud (AWS, GCP, Azure) and physical data centers, continuously assessing attack surface and identifying security gaps.
  2. Design and architect new network connection patterns and zone segmentation strategies that reduce risk while enabling product scalability.
  3. Build scalable monitoring, alerting, and automation solutions targeting network security risks across a fast-moving, dynamic environment.
  4. Lead threat modeling efforts focused on network architecture, data flows, and connectivity patterns across platform services.
  5. Evaluate current threat landscape and business priorities to effectively sequence and drive the highest-impact security improvements.

Skills

Required

  • Deep networking expertise across hybrid environments — public cloud (AWS, GCP, Azure) and physical data center networking — including routing, segmentation, zone design, and traffic inspection architectures.
  • Strong protocol knowledge including TCP/IP, HTTP/S, DNS, TLS, and applied cryptography.
  • Solid experience identifying network security gaps and designing scalable, secure connection patterns in SaaS or cloud-native product environments.
  • Experience building scalable monitoring, alerting, and automation solutions for network security use cases.
  • Scripting and automation capabilities in Python, Go, shell, or equivalent languages.
  • Experience working with teams that engineer and bring products to market in fast-paced, forward-looking environments.
  • Understanding of security architecture principles across the SDLC.
  • Demonstrated ability to operate independently on ambiguous, poorly-understood problems and drive them to resolution.
  • Excellent communication skills — able to lead technical debates, build consensus, and clearly articulate complex security concepts to varied audiences.
  • A combination of confidence, independence, clear thinking, and a collaborative mindset.

Nice to have

  • Experience with IaaS/PaaS networking constructs (VPCs, transit gateways, private endpoints, service meshes, etc.).
  • Familiarity with Zero Trust network architecture principles and implementation patterns.
  • Experience with security automation and orchestration tools.
