  • Evaluate and implement best practices for multi-agent communication, coordination, and lifecycle management.
  • Build and maintain backend systems handling large-scale scraping, search indexing, and querying pipelines.
  • Implement scalable APIs (REST, GraphQL) that serve search and agent-based results with high availability and low latency.
  • Optimize backend systems for performance, scalability, and cost efficiency, ensuring robust monitoring and alerts.
  • Develop verifiable execution deployment pipelines for web3 AI agents that execute yield bearing strategies on chain.
  • Leverage traditional keyword search (e.g., Lucene/Elasticsearch), as well as semantic vector-based search (FAISS, Milvus, Pinecone, etc.).
  • Integrate embeddings (OpenAI, Hugging Face) and advanced NLP models into production-grade systems.
  • Perform team wide collaboration & product alignment
  • Work closely with frontend and product teams to align backend capabilities with end-user requirements.
  • Collaborate with cross-functional teams to integrate AI and search functionalities into various data products.
  • Stay up-to-date with advancements in search technologies, NLP models, AI agent architectures, and frameworks.
