Senior Software Engineer (Machine Learning)
You will design, train and ship recommendation and ranking models (embeddings, collaborative filtering, ANN search), build Python services served at low latency (re-ranking under a 200 ms budget), run daily batch pipelines for many merchants, extend LLM shopping assistant work, and own deployments and observability (containers, Kubernetes, autoscaling, dashboards, alerts). The role expects 5+ years building ML systems with production model-serving experience and strong experience in Python, vector DBs, ANN libraries, SQL, Docker/Kubernetes, and A/B testing.
