Job description

Exa is an applied AI lab building a search engine unlike the world has ever seen. We build massive-scale infra to crawl the entire web, train state-of-the-art embedding models to process it, and design super high performant vector databases to retrieve over it. We now power search for Cursor, Cognition, HubSpot, and over 400,000 developers and have raised $350m from Lightspeed, Benchmark, and a16z. Our ultimate goal is to build perfect search over all the world's information, far beyond Google.

• You have owned compliance efforts such as HIPPA, SOC2, etc.
• You are comfortable with security hardening and any other details needed to make engineering systems run smoothly (VPN, development servers, etc.)
• You are super vigilant about vulnerabilities, potential attacks, and abuse, and constantly think about how to operate securely with the introduction of new technologies (OS-level, AI coding agents, etc.)

Example Projects

• Build a secrets management and rotation system used across distributed services, training jobs, and GPU clusters without impacting developer velocity
• Build monitoring and alerting for anomalous behavior across APIs, internal services, and customer usage
