Recommender Systems jobs

Recommender systems remain the quiet moneymaker of machine learning — ranking feeds, product suggestions, and ads at companies where a half-percent lift moves real revenue. LLMs are creeping in at the retrieval and cold-start edges, which keeps the field more interesting than its reputation.

Underneath the titles sit two-tower models, learned embeddings, feature stores, and the A/B testing discipline to prove any of it mattered. Postings concentrate at marketplaces, streaming services, and social platforms, so the employer list looks different from the rest of AI hiring. Scale experience counts for more than model novelty, and compensation at the big platforms reflects it.
