  • Improve vector search and similarity matching models to identify relevant documents across structured and unstructured data
  • Analyze user interactions and system performance to guide algorithmic improvements
  • Work across ML, infrastructure, and product teams to deploy fast and efficient RAG workflows
  • Build and maintain retrieval indexes optimized for latency and memory 
Essential Qualifications 
  • 7+ years of software development experience with exposure to ML engineering
  • Strong foundation in recommender systems, embeddings, and ranking models
  • Experience building or scaling document search or retrieval systems
  • Familiarity with vector databases (e.g., FAISS, Pinecone, Qdrant)
  • Proficient in Python and one systems language (e.g., C++, Java) 
Preferred Skills 
  • Background in LLM integration or fine-tuning for RAG workflows
  • Industry experience at companies like Google (Search, YouTube), Meta (Feed, Ads), or Twitter (Timeline, Trends)
  • Experience with ML pipeline tools (Airflow, Ray, TorchServe)
  • Previous experience improving search relevance, click-through rate, or long-term engagement 

Salary Range:  $150,000 - $250,000
