Software Engineering Manager, Network Security

About Anthropic

Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems.

About the role

The Network Security team's remit is to secure Anthropic's networks across our cloud providers and our bare-metal AI data centers. We own egress and ingress controls, network segmentation, private connectivity between environments, and encryption in transit. We design, build, and maintain these controls, and we write the software that deploys, enforces, and monitors them. These controls protect our model weights, customer data, and internal assets.

We are hiring an Engineering Manager to lead this team. Anthropic is adding data center sites and cloud regions quickly, and the team will grow with that work. In this role you will set the team's charter, practices, and priorities. You will partner with our infrastructure networking, cluster, and data center teams so security is built into network designs from the start. The goal is secure-by-default networking that lets research and product teams use compute in any environment without slowing them down.

Key responsibilities

We're hiring an Engineering Manager to lead a Network Security Engineering team in executing across critical initiatives including, but not limited to:

- Own the network security roadmap: threat model from the management plane through Kubernetes and cloud interconnects, decide what to build, and deliver it

- Be able to reason about the design and implementation of default-deny ingress and egress, segmentation between research, training, and production, private connectivity, and mTLS/service identity across every environment

- Ship these as secure-by-default primitives so new clusters, VPCs, and data center links inherit the right boundaries without security on the critical path

- Join networking, cluster, and data center teams at design time so topology, routing, and firewall decisions carry our invariants from day one

- Build visibility into traffic and boundary drift, with detection for exfiltration paths and automated remediation where safe

- Own the network security evidence for our security goals and compliance: the invariants hold, and you can prove it

- Hire, grow, and retain senior security software engineers; own their career development, and set the practices the team runs on as it scales

Minimum Requirements:

- 8+ years of front line management experience

- Low ego, high empathy; has built diverse teams and has former reports who would work for them again
