From the original posting
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. If you want to build massive-scale ML systems that will define the way the new AI world consumes information, this is the place for you.
We are hiring a Security Engineer to build the protective shield for all of Exa’s systems. These systems include: processing web scale data, indexing hundreds of billions of pages, training foundational models on TBs of data, serving thousands of enterprise customers from our endpoints. You will be critical in making Exa run securely while ensuring our shipping velocity.
Desired Experience
You have hands-on experience in building and maintaining secure infrastructure
You know your way around cloud security fundamentals, including multi-account AWS permissions and architectures, IAM design, secure CI/CD pipelines
You are fluent in secrets management, key management, and certificate lifecycles (rotation, revocation, automation)
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
Create security incident response playbooks and lead incident handling, from detection to post-mortem
