About the role

Senior Data Scientist / Analyst focused on analytics for institutional relationships (market makers, large takers, brokerages). Owns counterparty analytics, commercial interpretations, and documentation in a fast-moving environment.

Responsibilities

  • Own the analytics on our largest makers, takers, and brokerages, and be the internal source of truth on how each relationship is performing
  • Build the account-level view of every major counterparty — volume, flow composition, spread capture, fee and rebate economics, and how each has trended over time
  • Monitor counterparty health and surface concentration risk, deteriorating engagement, or churn signals early enough for the team to act on them
  • Analyze trading behavior to understand how each participant actually makes money on our platform, and whether the terms we have given them still make sense
  • Support the institutional team through reviews and negotiations with the analysis behind them — what a counterparty is worth, what they are asking for, and what we should be willing to give
  • Quantify how institutional flow affects the broader market, including liquidity, spreads, and the experience of retail traders on the other side of it
  • Work with analytics engineers to turn recurring relationship reporting into modeled datasets, so account reviews do not start from scratch every quarter
  • Own documentation end-to-end — writing clearly and thoroughly enough that anyone on the team can pick up your analysis without friction

Qualifications

  • 7+ years in analytics, trading, or counterparty analysis, ideally at an exchange, trading venue, brokerage, or market making firm
  • Expert SQL — you can work directly against order book and transaction-level data without supervision
  • Deep understanding of how professional participants make money — spread capture, adverse selection, inventory risk, and the economics of providing liquidity
  • Credibility in a technical conversation with a sophisticated counterparty — you can hold your own with a firm's own quants
  • Commercial instinct — you can look at a relationship and articulate what it is worth to us and where the leverage sits
  • Strong communication and discretion, including with sensitive counterparty information and in front of external partners
  • Comfortable operating in a fast-moving environment where business logic changes frequently and you need to keep pace
  • (Plus) Experience with institutional pricing, fee tiers, or rebate program design
  • (Plus) Familiarity with on-chain data or blockchain analytics
  • (Plus) Python or R for deeper statistical work on trading behavior
  • (Plus) Experience in fintech, crypto, prediction markets, or other data-intensive financial products
