The Opportunity

You will own the machine learning that powers product discovery for our merchants: personalized search ranking, recommendation widgets, email recommendations, and an LLM shopping assistant. This is an end-to-end role. You will train the models, build the services that serve them, and keep both running in production. You will not hand a model over a wall to someone else.

The team is small and the systems are real: Recommendations are re-ranked in the live request path for storefronts, under a 200 ms budget, measured by merchant conversion.

---

Responsibilities

• Design, train and ship recommendation and ranking models - session-based embeddings, collaborative filtering, content and visual embeddings.
• Build and operate the Python services that serve them at low latency.
• Run the batch pipelines that rebuild model artifacts daily across hundreds of merchants.
• Design and read AB tests; decide what ships on the evidence.
• Own your deployments: containers, Kubernetes manifests, autoscaling, dashboards, alerts.
• Extend our LLM work - a shopping assistant and LLM-assisted catalogue enrichment - with proper evaluation behind it.

---

Requirements

• 5+ years building machine learning systems, with at least 3 years of models serving live production traffic.
• Strong Python, (FastAPI or equivalent).
• Vector databases (Qdrant).
• Other ANN libraries - FAISS, Annoy, ScaNN. HNSWlib is what we run, but the trade-offs transfer.
• Hands-on recommender systems or search ranking experience: implicit feedback, embeddings, approximate nearest neighbour search.
• Solid SQL against analytical stores; ClickHouse experience is a plus.
• Comfortable with Docker and Kubernetes, and willing to own the deployment of your own work.
• Experience running AB tests and reporting results you did not like.
• Streaming systems (Pulsar, Kafka, Flink)

Values

You exemplify Maropost’s Values:

• Customer Obsessed
• Extreme Urgency
• Excellence
• Resourceful
