- Deep understanding of order books, matching engines, market data services, trade state machines, fund settlement, or exchange backend architectures.
- Knowledge of CTF, prediction markets, oracles, and off-chain matching + on-chain settlement design patterns.
- Strong security awareness to identify risks like reentrancy, price manipulation, signature replay, settlement errors, permission issues, and service outages.
- Ability to drive engineering execution in environments with immature chain ecosystems.
