- Build and improve full-stack experiences for Talent Matching, Talent Rediscovery, and related talent discovery workflows
- Design and ship search-backed capabilities using OpenSearch or Elasticsearch, including indexing strategies, query design, relevance tuning, ranking improvements, and semantic retrieval patterns
- Develop matching systems that combine keyword, structured, and semantic signals, applying AI/ML techniques such as embeddings, similarity search, classification, and ranking to improve match quality and consistency
- Partner with Applied ML and cross-functional engineering teams to evaluate trade-offs across relevance, latency, reliability, infrastructure cost, and user trust
- Mentor and guide junior and mid-level engineers, conduct thorough code reviews, and contribute to team engineering practices
You should have
