  • Exposure to a wide range of popular recommendation and personalisation techniques, including collaborative filtering, deep retrieval models (e. g., two-tower), learning-to-rank, embeddings with ANN search, and LLM approaches for sparse data personalisation.
  • Exposure to training models OR deploying them - experience with end-to-end ML pipelines.
  • Understand offline and online evaluation, A/B testing, and metric alignment.
  • Experience with vector search, graph-based algorithms and LLM-based approaches is a big plus.
