What you’ll 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 world. In 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 CoreWeave’s 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 CoreWeave’s 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, an
