You will work in a high-scale environment (CoreWeave is positioning itself as the next major hyperscaler) and ensure our network and services remain secure, resilient, and trustworthy. The ideal candidate is a seasoned security expert (5–10 years experience) with a deep understanding of modern cloud/network architectures and a passion for mentoring others in a security-first culture.Key Responsibilities• Network Security Architecture: Design and deploy robust security measures across the network perimeter and internal fabrics (e.g., firewalls, IPS/IDS, segmentation, configuration health, best practicies) to protect CoreWeave’s globally distributed hyperscale infrastructure hosting large-scale AI workloads. Ensure that all entry points, high-speed interconnects, and cloud services are fortified against unauthorized access and attacks.• Zero Trust Implementation: Champion a Zero Trust security model across CoreWeave’s network and cloud environments. Architect solutions that enforce least-privilege access, continuous verification, and micro-segmentation of services – ensuring no implicit trust at any layer.• Security Monitoring & Incident Response: Establish robust monitoring for network security events and potential breaches across high-density AI cluster networks. Proactively identify vulnerabilities or indicators of compromise, and coordinate incident response efforts for any network-related security incidents to minimize impact.• Cross-Functional Collaboration: Work closely with Networking, Infrastructure, and Software Engineering teams to integrate security best practices into architecture, deployments, and processes. Provide expert guidance during design and code reviews to ensure new services and features are secure by design.• AI Infrastructure & Interconnect Security: Secure high-density GPU clusters and ultra-low latency backend fabrics. Implement security controls to protect customer data in transport.• Leadership & Mentorship: Drive security initiatives and foster a security-first mindset across the organization. Mentor junior engineers and peer teams on network security principles, conduct security training sessions, and lead by example in following and enforcing security policies and standards.• Policy Development: Develop, implement, and continually refine security policies and standard operating procedures for a highly scalable, distributed environment. Regularly review network and cloud security postures, ensuring compliance with industry best practices and adapting policies as the company grows.Required Qualifications• Experience: 5–10 years of hands-on experience in network security engineering, with exposure to large-scale cloud or hyperscaler environments. Proven track record protecting complex, distributed systems at scale.• Network Security Expertise: Deep understanding of network security principles and technologies – including experience mitigating DDoS attacks, securing high-speed data center fabrics, defending against web exploits, and implementing zero trust methodologies.• Cloud & Network Architecture: Strong conceptual and practical knowledge of securing modern cloud and network architectures. Proficient in network protocols (TCP/IP, DNS, BGP, etc.), network segmentation, VPNs, and firewall configurations. Experience securing cloud platforms (AWS, GCP, Azure or custom hyperscale infrastructure) and containerized environments.• Security Leadership: Demonstrated ability to lead security initiatives and projects end-to-end. Experience mentoring engineers or leading security teams, with a talent for instilling a security-first mindset across diverse teams.• Cross-Team Collaboration: Excellent communication and collaboration skills. Ability to work closely with cross-functional teams (Networking, Infrastructure, DevOps/SRE, Software) to design and implement security solutions that enable the business while protecting critical assets.• Policy and Compliance: Experience in designing, implementing, and reviewing security policies and controls for highly scalable, distributed systems. Familiarity with industry standards and compliance frameworks (e.g., NIST, ISO 27001, SOC2) and how they apply in a cloud environment.
