Staff / Senior Software Engineer (Security Fusion Platform)

About this role

• Data Center Security Engineering (DCSE) owns physical security across Anthropic’s data center footprint: the sites, the hardware inside them, and the supply chain that delivers it
• The Security Fusion Platform is where physical security signals from across that footprint are correlated and put in front of the analysts who act on them
• It carries continuous monitoring, audit evidence, metrics, and analyst response, along with the classification and analytics pipelines that turn sensor data into events
• You’ll build and own the platform analysts work from
• This is a foundational role
• You’ll build the software platform that carries a signal from source to analyst decision, ship its first versions, and keep them running in production
• The sensors and systems at each site belong to other DCSE engineers; you define the event contract their owners deliver to, and you build the classification and analytics pipelines that run over what those sources produce
• Physical security systems engineers own the operations spaces; you own the software that runs in them
• You’ll work alongside engineers focused on the sites themselves
• What you lead, you own end to end: the design, the technical approach, and the result in production
• You’ll work with external vendors and integrators, setting requirements and acceptance criteria for what you own and deciding what the team builds itself
• We use Claude throughout our engineering workflow and expect you to as well
• This role involves regular travel to data center sites
• No security clearance is required
• These are critical services, and you’ll take part in on-call for them
• Design and build the event bus and normalized event schema: source identity, sequencing, health state, and the adapter contract that owners of each sensor and system feed build to, plus adapters where needed
• Build correlation and alerting: the rules and services that turn events from independent sources into alerts an analyst can act on
• Build the cl...
