About the role

Role focused on designing, specifying, testing, and validating Anthropic's physical security systems for data centers, including perimeter barriers, intrusion detection, video, lighting, and site hardening. Owns the physical security reference design package, sets site-specific engineering basis, and collaborates with vendors, DCSE, design/construction/real estate teams. Regular travel to data center sites and on-call rotation.

Responsibilities

  • Produce a vendor-ready design package for perimeter barriers and hostile vehicle mitigation, intrusion detection and its zoning, video coverage, security lighting matched to camera performance, and penetration protection: performance specifications, typical details and reference drawings, and device and zone schedules, written so a design firm can build to them and a test can prove them
  • Define the per-site engineering basis: which requirements apply to a site based on its risk profile and the threats it faces, with compensating controls and documented deviations
  • Write the acceptance criteria and test methods: the verification method behind each requirement and the evidence a site must produce to pass acceptance
  • Set standoff, structural hardening, and site layout criteria for new designs, tied to the threat basis they derive from
  • Run field verification: commissioning and acceptance testing of perimeter, detection, video, and lighting against performance criteria (detection coverage tests, photometric measurements, video quality checks)
  • Write the operational and design requirements for security operations control rooms: console layout, wall versus workstation content, supervisor placement; room network, power, backup, and resilient communications to the team's segmentation and hardening baseline
  • Own control room acceptance: factory and site acceptance criteria written before the build, then accept or reject delivered systems (video wall, consoles, cabling, fit-out) against them

Qualifications

  • Have designed or specified physical security systems (perimeter barriers, intrusion detection, video, security lighting) for campus-scale sites: multiple buildings, a secured perimeter, many detection zones
  • Read and produce construction documents (site plans, civil and electrical drawings, device schedules, submittals) using standard design and markup tools such as AutoCAD, Revit, or Bluebeam
  • Write performance requirements that are testable: each states what must be true, how it will be verified, and what evidence shows it
  • Have run commissioning and acceptance tests against performance criteria and rejected work that did not meet them
  • Derive requirements from a threat basis rather than a product catalog: you can say which adversary a control stops and where the next weakest point is
  • Have owned an engineering domain where you set the approach, chose what applied to each site, worked directly with vendors, and answered for the result
