Machine Learning Engineer III, Search Relevance

Join Box, the leader in Intelligent Content Management. As a Machine Learning Engineer III, you will improve search quality and build scalable, low-latency services that serve queries in real time. You will collaborate with senior engineers, Product, Data, and Infra partners to productionize modern retrieval techniques and experimentation frameworks. This is a unique opportunity to work at the intersection of information retrieval science, applied machine learning, and large-scale distributed systems.

• Design, build, and iterate on components for ranking, retrieval, and recommendations that improve measurable relevance and latency.
• Implement production features leveraging embeddings, semantic/hybrid search, and LLM-enabled retrieval under mentorship and design guidance.
• Contribute to offline/online evaluation, A/B tests, and relevance tuning using metrics such as NDCG, MRR, and precision@k.
