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

Experience managing infrastructure or security engineering teams, including hiring, developing, and managing senior and staff engineers

Has grown engineers into staff or lead roles, and has made the call to move someone out when coaching didn't work

Kept a team intact and delivering through reorgs, charter changes, or leadership turnover

Experience owning a security or infrastructure domain end to end: setting multi-year strategy, delivering year-long cross-organizational work with little direction, and answering to executives for its risk and tradeoffs

Scaled a team and its systems together through hypergrowth, where last quarter's architecture was already too small

Hands-on network security engineering in cloud and/or on-prem environments: VPC design, interconnects, private service connectivity, cloud firewall policy, egress control, physical segmentation, and out-of-band/management-plane security

Threat modeling and risk assessment for networked systems, with the judgment to tell which controls reduce risk and which just look good on a diagram

Secured Kubernetes networking at scale, or worked in high-assurance environments where controls had to be evidenced, not just deployed
