[…] is the web search engine built for AI. Our infrastructure crawls, indexes and serves the live web to AI agents, and it’s scaling fast. We’re looking for a top‑tier Machine Learning Engineer to join […] and work hand‑in‑hand with our CTO, Denis Charrier , and the rest of the tech team.

Design, train and ship ranking and retrieval models for AI agents Design, train and ship ranking and retrieval models for AI agents

Bring new ranking signals into the engine, beyond pure relevance

Build the evaluation framework that tells us what really improves search quality

Optimize model serving for latency and GPU cost

Turn customer and benchmark feedback into ranking improvements, with clear before/after numbers

Are excited to help build Google for AI agents- and believe in […]’s mission

Have strong hands-on experience in information retrieval, ranking or search in production.

Build rigorous evals and check the data behind every number

Care about latency, cost and reliability as much as model quality

Thrive in a fast-paced, high-ownership startup environment

Ship a new ranking model to production and prove the gain on our eval sets

Push our models to the next level: better answers, lower latency, lower cost per query

Build and maintain the evaluations framework that measures every change to our search engine
