• Lead data forensics during incidents, including pre/post-trade analysis
• Quantify user impact and develop fixes to reduce recurrence

Requirements

• Working knowledge of core DeFi primitives and on-chain signals
• Understanding of oracle price feed construction and common failure modes
• On-chain data fluency, including reading EVM logs/traces and understanding token standards
• Blockchain fundamentals impacting alerting and incident response
• Awareness of market microstructure and benchmark construction

Preferred Skills

• Experience with Chainlink data products and oracle attack surfaces
• Ability to read smart contracts in Solidity/Rust
• Experience in anomaly detection for financial time series
• Proficiency in Python/SQL with web3 libraries
• Portfolio demonstrating protocol health dashboards and data quality detectors

Benefits

All roles are global and remote-based. We aim to have some working hours overlap with Eastern Standard Time (EST).
