Sr. Product Security Engineer, Network and Infrastructure

CrowdStrike is a global leader in cybersecurity, dedicated to stopping breaches with an advanced AI-native platform. The Sr. Product Security Engineer will serve as a network security expert, focusing on identifying security gaps, reducing attack surfaces, and driving strategic initiatives across the product and engineering organizations.

Responsibilities:

• 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
• Design and architect new network connection patterns and zone segmentation strategies that reduce risk while enabling product scalability
• Build scalable monitoring, alerting, and automation solutions targeting network security risks across a fast-moving, dynamic environment
• Lead threat modeling efforts focused on network architecture, data flows, and connectivity patterns across platform services
• Evaluate current threat landscape and business priorities to effectively sequence and drive the highest-impact security improvements
• Lead complex, cross-team security initiatives with broad impact across the product group
• Contribute to medium-term strategic direction for network security; proactively identify areas of greatest need and develop actionable plans to address them
• Provide architectural and design expertise that accounts for the broader platform picture, not just point-in-time solutions
• Serve as an internal authority on network security architecture within CrowdStrike's product organization
• Volunteer for and lead working groups and initiatives that have impact at the Product team level or broader industry level
• Partner closely with product engineering, infrastructure, and platform teams to understand scaling requirements and translate them into secure-by-design network architectures
• Work across organizational boundaries to facilitate alignment on security requirements, driving consensus on complex and ambiguous problems
• Clearly communicate decisions and architectural direction to both technical and non-technical stakeholders once alignment is reached
• Serve as a role model for security culture and best practices within your functional area
• Multiply the effectiveness of the broader team by facilitating cross-team knowledge sharing and collaboration
• Guide and develop technical talent through coaching, code reviews, and architectural deep-dives
• Contribute to the growth of the security organization by mentoring team members and helping refine technical interviewing standards

Requirements:

• 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
• Proven experience utilizing AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency and drive business outcomes
• Bachelor's degree in Computer Science, Information Security, or equivalent field
• 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 CI/CD pipeline security and operational systems
• Understanding of compliance requirements and evidence collection in a regulated SaaS environment
• Prior experience in a formal mentorship or technical leadership capacity
