Job Description

Exa is building a search engine from scratch to serve every AI agent. We build massive-scale infrastructure to crawl the web, train state-of-the-art embedding models to process it, and design super high performant vector databases in rust to search over it. If you like compute, we also own a $5M H200 GPU cluster (and soon 5x'ing that) and regularly spin up batchjobs with tens of thousands of machines.

As a Full Stack Engineer at Exa, you'll work on everything developers and agents touch when they use our product. That includes our developer dashboard, APIs, SDKs, and the rest of our developer platform.

Who You Are

• You're a strong generalist engineer, comfortable owning the product lifecycle from design to deploy

• You're fluent in TypeScript, with a strong eye for front-end design, and comfortable learning new tools and technology as the work calls for it

• You've designed and maintained backend APIs that real users and customers depend on

• You've shipped products for LLMs, AI agents, or other systems used by many people

• You care about the problem of finding high quality information and recognize how important this is for the world

What You Could Do

• Build agentic onboarding flows that quickly get developers (and their agents) from sign-up to first integration

• Shape the Exa API and SDKs into the cleanest, most ergonomic agentic search platform in the ecosystem

• Architect the API gateway that every Exa request flows through

• Build account, billing, permissions, and provisioning surfaces our enterprise customers need

This is an in-person opportunity in San Francisco. We're happy to sponsor international candidates (e.g., STEM OPT, OPT, H1B, O1, E3). In addition to premium healthcare benefits (medical, dental, vision), we also offer fertility benefits and a monthly wellness stipend to all of our employees.
