Threat Intelligence Engineer

Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems.

We are looking for a Threat Intelligence Engineer to join our Threat Intelligence team. In this role, you will build the infrastructure that powers our threat discovery capabilities—integrating external data sources, developing detection systems for automated lead generation, and creating internal tooling that scales our investigators' impact. This is a foundational engineering role on a small, high-impact team. You will take projects from proof-of-concept to production, work closely with investigators to understand their needs, and help scale what may become a multi-person collections function.

• Build automated detection systems that use disparate signals to identify abusive behavior.
• Take systems from idea to proof-of-concept to production-grade with appropriate monitoring, documentation, and maintenance processes.
• Develop and maintain YARA rule infrastructure, including tools for writing, validating, and testing rules against real data.
• Create integrations with external threat intelligence platforms (e.g. VirusTotal, Censys, Urlscan) via MCP servers to enable multi-source correlation during investigations.
• Build data pipelines that ingest intelligence from RSS feeds, CTI news sources, and partner sharing, using Claude to extract TTPs and generate targeted hunting queries.
• Develop behavioral analytics capabilities using DBT-based frameworks and create searchable audit logging infrastructure.
• Establish feedback loops with investigators to tune detection systems and reduce false positives.
• Scrape and normalize data from external sources to feed threat detection and enrichment workflows.

• Strong coding proficiency in Python and SQL for building detection logic, data pipelines, and automation.
• Experience with data pipeline orchestration tools (Airflow, DBT, or similar).
• Familiarity with threat intelligence concepts including IOCs, YARA rules, and threat correlation techniques.
• Experience integrating external APIs and building data ingestion systems.
• Can translate investigator needs and workflows into technical requirements.
• Comfortable building v0 systems and iterating based on user feedback.
• Strong communication skills for working closely with non-engineering stakeholders.

• Experience with threat intelligence sharing frameworks (e.g. MISP, STIX/TAXII).
• Background in cyber threat intelligence, security operations, or abuse detection.
• Experience building MCP servers or similar tool integrations for AI systems.
• Familiarity with web scraping and data extraction at scale.
• Experience with behavioral analytics or anomaly detection systems.
• Understanding of LLM capabilities and how to leverage them for automation.
• A Top Secret Clearance.

Annual Salary: $320,000—$405,000 USD. Anthropic offers competitive compensation and benefits, optional equity donation matching, generous vacation and parental leave, flexible working hours, and a lovely office space in which to collaborate with colleagues.
