Tavily, part of Nebius, is the web access layer for AI agents
Over two million developers use us, and our customers include Fortune 500 companies running agents in production.
</p> <p>We build and run our own index.
That means we own the hard problems directly: crawl coverage at scale, freshness, cost per query, and the quality of what comes back.
This role owns that infrastructure as a product.
</p> <p>When an agent asks a question, the answer has to be relevant, fresh, fast, and affordable.
Those four things pull against each other, and someone has to decide which one gives.
That is you.
You will set what good means for each use case we serve and the bar a change has to clear before it ships, working closely with our evaluation team, who own how we measure it.
You will also shape where our index goes next: what it needs to cover, how fresh it needs to be, and what it has to be good at.
</p> <p>The most open part of the job is what comes next.
Search is being rebuilt for a consumer that is not a person.
Agents do not want one result page, they want to break a problem apart, run many retrievals, and decide what to do next.
That changes what search infrastructure should look like, and part of your job is to have a view on where ours should go.
</p> <p>The hard part is deciding what good enough means.
Perfect coverage, perfect freshness, and low cost cannot all be true at once, and the person in this seat is the one who has to make that call for each use case and defend it.
</p> <p>In your first year, we expect you to set a clear quality bar for our search products that the team builds against, have a real influence on where our index goes next, and bring us a point of view on where search infrastructure is heading.
</p> <p>This is a hands-on senior IC role with real ownership, reporting to the Director of Product.
You will work day to day with our search engineering and research teams, with the eval.
