📋 Description

• Triage incoming alerts and referrals daily against documented investigation thresholds, set priority and next steps, and identify novel signals. • Trace flagged wallets across chains, bridges, and funding flows, distinguish controlling wallets from contract and proxy wallets, cluster related addresses, and follow withdrawal paths to disposition. • Review order-book and execution data for spoofing, layering, wash trading, and coordinated multi-account activity, linking behavior to the wallets involved. • Investigate insider trading, oracle and resolution-source manipulation, bot and automated-trading abuse, sanctions exposure, and illicit-finance flows. • Write queries, build lightweight analysis, and propose new detection signals. • Document every matter with clear, sourced, audit-ready findings framed as suspected rather than confirmed. • Handle law enforcement and regulatory requests, including subpoenas, preservation letters, and court orders, while tracking deadlines and escalating unusual matters to legal counsel.

🎯 Requirements

• 3+ years in trade surveillance, on-chain investigations, blockchain analytics, financial crime investigation, or exchange operations • Strong DeFi experience can offset lighter traditional-surveillance tenure, and vice versa • Hands-on wallet tracing across blockchains, including funding flows, withdrawal paths, bridges, mixers, and address clustering • Working knowledge of order-book manipulation typologies, including spoofing, layering, wash trading, and coordinated multi-account activity • Understanding of exchange trading and order-book mechanics • Proficiency in SQL or a comparable query language for trading, device/IP, and on-chain data • Strong written communication for legally and regulatorily defensible case documentation • Familiarity with prediction markets, crypto-native platforms, market resolution, and market integrity • Experience with Chainalysis, TRM Labs, or Elliptic is a plus • Experience with automated trade-surveillance platforms such as Nasdaq SMARTS is a plus • Familiarity with oracle and market-resolution mechanisms is a plus • Prior regulated financial-environment or sanctions and illicit-finance screening experience is a plus • Python or similar scripting is a plus
