About the role

Engineering Manager leading Anthropic's Network Security Engineering team to secure network infrastructure across cloud providers and bare-metal data centers, delivering secure-by-default networking and enabling researchers and product teams to operate securely in any environment.

Responsibilities

  • 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

Qualifications

  • 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
