Security Engineering Manager, Network Security

Security Engineering Manager Network Security

What youll do:

CoreWeave is the AI hyperscaler operating infrastructure at a scale and level of complexity required to support the most demanding AI workloads in the this role you will lead network security for the platform shaping how security is designed into the network foundations that power large scale GPU clusters and distributed AI workloads. You will operate at the intersection of performance reliability and isolation where network design choices have direct impact on customer workloads. You will partner deeply with Networking Infrastructure and SRE to influence how next generation network fabrics overlay architectures and infrastructure offload technologies are built and operated. You will lead and grow a team of network security engineers while defining how network security scales alongside the platform.

About the role:

• CoreWeave is the leading specialized cloud computing provider offering GPU accelerated infrastructure for AI machine learning and other computationally intensive workloads.
• CoreWeave has rapidly grown into a key player in the AI cloud space and operates large scale infrastructure across multiple U.S. data centers supporting high performance latency sensitive workloads for some of the most demanding customers in the world.
• As CoreWeave continues its rapid growth securing the underlying network that powers this platform is a critical priority.
• CoreWeave operates high performance HPC grade networking including InfiniBand fabrics and modern overlay based network architectures to support large scale distributed AI workloads.
• These environments place unique demands on network security where performance isolation and reliability must be designed together rather than treated as separate concerns.
• This role is responsible for running evolving and operating CoreWeaves network security program and engineering team in close partnership with Networking Infrastructure SRE and other security teams.

Core job duties include but are not limited to:

• Own the strategy and evolution of CoreWeaves network security posture across the network fabric control planes and edge.
• Partner with Networking to design and secure large scale network architectures including modern overlay and segmentation based designs such as EVPN VXLAN and VRF based isolation.
• Help define and guide the security model for high performance networking environments including InfiniBand fabrics and other performance sensitive interconnects.
• Guide the security implications of infrastructure offload patterns including the use of DPUs and SmartNICs for networking and policy enforcement.
• Lead grow and develop a team of network security engineers through mentorship technical direction and performance management.
• Drive the design and maturity of DDoS mitigation and traffic defense capabilities balancing in house systems with third party platforms where appropriate.
• Act as an escalation point for complex network security incidents partnering with detection response and reliability teams to improve visibility automation and recovery.
• Define and evolve network security standards guardrails and metrics that scale with the platform.
• Ensure network security controls support compliance requirements and customer commitments through automation and measurable outcomes.
• Influence secure by design decisions across infrastructure networking and security through partnership rather than gatekeeping.

Who you are:

• You have 7 to 12 or more years of experience in network infrastructure or platform security within large scale cloud hyperscaler ISP or high performance computing environments.
• You have 3 to 5 or more years of experience leading or managing engineers either as a people manager or technical leader with people responsibility.
• You have strong foundational knowledge of networking concepts including TCP/IP routing BGP DNS TLS segmentation and control plane security.
• You have experience securing modern network architectures including overlay based designs and multi tenant environments.
• You are comfortable reasoning about complex distributed systems and applying sound security judgment in performance sensitive environments.
• You communicate clearly and partner effectively across disciplines including Networking Infrastructure and SRE.
• You bring a pragmatic systems oriented mindset and are comfortable making tradeoffs in fast moving environments.

Preferred:

• Experience operating or securing high performance or HPC grade networks including InfiniBand based fabrics.
• Hands on exposure to large scale fabric networking and performance sensitive traffic patterns.
• Experience with DPUs SmartNICs or similar infrastructure offload technologies.
• Experience with Kubernetes networking containerized environments and CNI based policy enforcement.
• Proficiency with automation or programming languages such as Python or Go.
• Familiarity with security frameworks such as NIST ISO or SOC2 in the context of infrastructure and platform security.
• Experience partnering closely with incident response detection engineering or reliability teams during complex incidents.

Wondering if youre a good fit
