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.
What you will do:
- Ingest, clean, and normalize blockchain data (on-chain and off-chain) for high-performance querying.
- Develop ETL pipelines to fix incomplete, inconsistent, or corrupted blockchain data.
- Work with real-time transaction streams to enrich blockchain analytics with off-chain sources.
- Optimize blockchain indexing for fast querying in Snowflake and ClickHouse.
- Integrate off-chain data (DeFi, NFT, market prices, exchange data, KYC) into blockchain analytics.
- Improve data enrichment strategies to provide context-aware analysis.
- Build scalable systems to process high-throughput blockchain transactions and queries.
- Deploy and optimize cloud workloads on GCP with Kubernetes and containerized processing.
You might thrive in this role if you:
- Have a BS/MS/PhD in Computer Science or a related field.
- Have 5+ years of experience in blockchain analytics, AI/ML, distributed search, or large-scale data processing.
- Have strong programming skills in Python, TypeScript, or Node.js.
- Have expertise in database design (SQL and NoSQL) and high-throughput data systems.
- Have experience working with raw blockchain data (e.g., transaction traces, smart contract events, mempools, logs, receipts, state diffs, opcodes).
- Are familiar with EVM and non-EVM chains (Ethereum, Solana, Sui, Aptos).
- Have a strong understanding of tokenomics, governance models, and cross-chain interoperability.
- Have hands-on experience with Snowflake, ClickHouse, RocksDB, and vector databases.
- Have experience with web crawling, data scraping, and large-scale ingestion pipelines.
- Are passionate about blockchain, AI search, and distributed systems.
Why join us?
- Work on cutting-edge generative AI and search technologies applied to blockchain.
- Solve complex challenges in large-scale indexing, vector search, and AI-powered retrieval.
- Be part of a high-caliber team of former founders, engineers, and executives from leading tech and financial firms.
- Competitive salary and equity opportunities.
- Fully remote team with a fast-moving, high-impact culture.
- Own and shape the future of AI-driven search and retrieval for Web3.
