Recidivism & Ban Enforcement Analyst

Anthropic; San Francisco (CA); Hybrid; USD 245,000 - 285,000; Full time

Job summary

Anthropic in San Francisco is seeking a Safeguards Enforcement Analyst to build and run enforcement workflows that keep our products safe. The role focuses on detecting and mitigating potential harm, with an initial emphasis on preventing recidivism: banned actors evading a ban within minutes across accounts.

You will investigate evasion clusters, link accounts across identities, and operationalize re-registration controls for high-severity bans.

Qualifications

• Experience investigating ban evasion, multi-accounting, or repeat fraud actors.
• Fluency in SQL and ability to run analyses across large account and event datasets.
• Experience with fraud/identity-linking signals and precision/recall tradeoffs.
• Rigorous evidence standards; comfort with the asymmetric cost of false positives in severe-harm enforcement.
• A track record of turning one-off investigations into repeatable detection logic and policy.
• Strong written communication skills, with experience producing clear briefs and recommendations for technical and non-technical stakeholders.
• Excellent judgment and the ability to collaborate with team members while navigating rapidly evolving priorities and workstreams.

Responsibilities

• Investigate evasion clusters end to end—from a single appeal or signal anomaly to the full linked actor network.
• Convert individual findings into durable systemic controls and detection proposals.
• Operationalize re-registration controls for high-severity ban populations.
• Partner with Engineering and Data Science teams on account-linking signals to connect returning actors across identities.
• Build the recidivism measurement framework: how often banned actors return, how fast we catch them, and which controls reduce return rates.
• Author playbooks for contractor-supported evasion review with QA against your own gold standard.
• Keep up to date with emerging AI policy enforcement best practices, and use these to inform our decision-making and workflows.
