- Understanding of blockchain fundamentals (account model/UTXO, consensus mechanisms, gas mechanics).
- Understanding of on-chain data structures for major public chains (Ethereum, BSC, Solana, Bitcoin, etc.) — blocks, transactions, event logs, token transfers (ERC-20/ERC-721).
- Experience with on-chain data collection/parsing is a plus — e.g. building or integrating with The Graph, Dune, Etherscan API, or node RPCs.
- Understanding of DeFi, NFT, or cross-chain bridge business models and their data characteristics is a plus.
- Data engineering experience at an exchange, wallet, DeFi protocol, or on-chain analytics company is a plus.
- Fluent English reading/writing; able to independently read English technical documentation (e.g. Ethereum Yellow Paper, RFCs/EIPs, AI papers) and write technical proposals and weekly reports in English.
