Senior Manager, Strategic Finance & Business Analytics, Polymarket US

Responsibilities

• Maintain and update the US revenue and gross margin forecast on a weekly basis, keeping it grounded in actual driver-level data across deposits, trading volume, payment methods, and costs.
• Build and refine cohort models that track customer behavior from acquisition through deposits, trading activity, and retention, segmented by channel, market, and customer type.
• Decompose payments, fraud, and incentive costs line by line to explain margin movements and identify where the business is making or losing money at the unit level.
• Own the weekly KPI reporting pack for US leadership, including defining the metrics, closing data gaps, and making sure the story the numbers tell is accurate and actionable.
• Partner with growth and product teams to size new market and channel opportunities, translating growth assumptions into funded account projections, volume estimates, and expected unit economics.
• Dig into specific cost categories, including liquidity programs, web hosting, onboarding, and transaction-driven expenses, to build detailed models that hold up under scrutiny.
• Take analyses from initial framing through final recommendation, presenting clearly to leadership and following through until a decision is made.

Requirements

• 5 or more years in strategic finance or business analytics, with a track record of doing the modeling work yourself, not just managing it.
• Demonstrated experience building driver-based financial models from scratch that other people can actually use and maintain.
• Deep familiarity with transaction-level unit economics. You know how to decompose margin by segment, channel, or payment method and explain what is driving the difference.
• Comfort working autonomously in a fast-moving environment where the data is imperfect and the questions keep changing.
• Experience defining KPIs, building reporting infrastructure, and creating dashboards that a finance or strategy team relies on week to week, not just for a one-time presentation.
• A specific example of analysis you produced that changed a leadership decision on pricing, market expansion, or resource allocation.

Nice to Have

• Prior experience at a fintech, crypto, or marketplace company where payments, fraud, and transaction economics were core to the business.
• Hands-on ability to write SQL and build self-serve dashboards in tools like Looker, Metabase, or similar.
