Security Engineer, RF and Technical Surveillance Countermeasures
Anthropic · San Francisco, CA | New York City, NY
About this role
**Security Engineer, RF and Technical Surveillance Countermeasures (TSCM)** **About Anthropic** Anthropic’s mission is to create reliable, interpretable, and steerable AI systems—safe and beneficial for users and society. **About the role** Claude is trained and served on hardware in Anthropic data centers and in partner sites. DCSE secures that footprint: the sites, the hardware moving through them, and the people and vendors who touch it. A key part of this footprint is the **radio spectrum around and inside each site**—what transmits, what listens, and what equipment emits. You’ll own this domain end to end: **on-site RF monitoring and detection**, **technical surveillance countermeasures (TSCM)**, and **emanations security**, from threat basis through the systems that make the spectrum observable, including sign-off before a site opens. You’ll also build the monitoring tooling that proves controls hold—**sensors/receivers placement, site baselines, and detection logic** that turns rogue or unexpected emitters into alerts analysts can trust. Specialist partners perform hands-on sweeps and measurements; you’ll define scope, direct them on site, and decide whether their findings stand. The goal is security that runs itself with continuous evidence verification and routine triage supported by tools and AI agents. **Location / travel** Based in **San Francisco** (remote applicants in the US considered). Regular travel to critical infrastructure data center sites is required. --- ## Key responsibilities - **On-site RF monitoring and detection:** Design and develop site monitoring (sensors/receivers/antennas, spectrum monitoring architecture, RF baselines, and detections that feed the security monitoring platform). - **Tools, automation, and AI agents:** Build detection/classification tooling, sweep-to-sweep checks, evidence records, and agents for alert triage and sensor health. - **Technical surveillance countermeasures (TSCM):** Own TSCM end to end (sweep cadence, event-driven triggers, scope/acceptance criteria, evidence handling and closure). - **Emanations security:** Set site posture (assessment method, zoning/separation, shielding/filtering/protected cabling) and embed requirements into design/build standards. - **Wireless and device policy by zone:** Detect which radios are present by zone and produce evidence that policy holds. - **Specialist partners:** Write sweep/assessment scope and deliverable standards, direct work on site, and perform acceptance review. - **New sites and leases:** Carry RF/emanations requirements into design reviews, lease terms, and pre-opening reviews; complete pre-opening sweep/assessment and sign-off. --- ## Minimum qualifications - Built at least one **RF monitoring/detection system end to end** (receiver/antenna choice through software that produces alerts). - Strong RF engineering understanding (propagation, modulation, spectrum analysis, antenna behavior) with hands-on use of instruments (e.g., spectrum analyzers, SDRs). - Planned and conducted **TSCM sweeps** and can explain what they can/can’t find and how an adversary could bypass them. - Hands-on experience with **RF security, TSCM, or emanations** for data centers/critical infrastructure/large hardware fleets. - Can read/review code, design data systems behind monitoring tooling, and build automation (often with AI coding agents) using **Git** and code review. - Understand compromising emanations and tradeoffs (zoning/shielding/filter
