Zark Lab is hiring a Senior AI/ML Engineer, Search 
About the Team:
Zark Lab is building foundation models for blockchain transactions and information. Our work focuses on search, retrieval, and generative modeling applied to on-chain and off-chain data. We are developing systems that enable efficient indexing, retrieval-augmented generation (RAG), and vector search for structured and unstructured blockchain datasets. Our models process billions of transactions and smart contracts across multiple blockchains, applying sequence modeling, graph-based learning, and language models to extract insights and improve data accessibility.
The team consists of former founders, senior engineers, and executives from Google, Meta, Goldman Sachs, and other leading technology and financial institutions. Our backgrounds span large-scale distributed systems, machine learning, engineering, and information retrieval, and we are focused on advancing the state of AI-driven search and computation for blockchains.
