About The Position

As a global leader in cybersecurity, CrowdStrike protects the people, processes and technologies that drive modern organizations. Since 2011, our mission hasn’t changed — we’re here to stop breaches, and we’ve redefined modern security with the world’s most advanced AI-native platform. Our customers span all industries, and they count on CrowdStrike to keep their businesses running, their communities safe and their lives moving forward. We’re also a mission-driven company. We cultivate a culture that gives every CrowdStriker both the flexibility and autonomy to own their careers. We’re always looking to add talented CrowdStrikers to the team who have limitless passion, a relentless focus on innovation and a fanatical commitment to our customers, our community and each other. Ready to join a mission that matters? The future of cybersecurity starts with you. About the Role: Help us protect the Security Cloud from the most advanced threats! CrowdStrike's Product Security team breaks the mold of traditional security teams and focuses on active threats to CrowdStrike's products and platform. As a Sr. Engineer II, Product Security, you will serve as a network security subject matter expert and trusted security partner across our product and engineering organizations. This isn't a role dedicated to managing firewall rules or security group configurations. You will develop deep expertise across our hybrid networks — spanning public cloud and physical data centers — to identify security gaps, reduce attack surface, and architect new connection patterns that scale with our business. Operating with full independence on poorly-understood and ambiguous problems, you will drive medium-to-long-term strategic direction for network security across the product group, while mentoring and multiplying the effectiveness of the engineers around you. This is a highly dynamic, hands-on role that requires both deep technical depth and the ability to lead cross-functional initiatives with broad organizational impact.

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.
Bachelor's degree in Computer Science, Information Security, or equivalent field.

Nice To Haves

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.

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.
