River Markets - Financial Ops Lead - San Francisco, CA
About The Position
River Markets is building the prime brokerage and execution layer for prediction markets, providing the necessary infrastructure for professional and institutional traders to access, trade, and manage risk across venues like Kalshi and Polymarket US at scale. The company was founded by individuals with backgrounds in HFT and hedge funds who identified a need for a proper execution and financing layer for prediction markets. Currently, River Markets is connected to three exchanges, operates six proprietary execution algorithms, and serves paying trading firms. The company values ownership, speed, precision, and a high technical bar, aiming to be a highly automated FCM that achieves more with a small team than traditional financial institutions. River Markets operates with an AI-native, control-first approach, utilizing AI and automation across the company. For this role, the focus is on ensuring that automation strengthens, rather than obscures, the control environment. The ideal candidate will be adept at identifying tasks that can be automated while designing the necessary checks, documentation, and human review processes to ensure trust in the automated results.
Requirements
- 2+ years of relevant experience at an NFA-regulated entity, such as an FCM, introducing broker, swap dealer, or DCM.
- Direct experience with customer-fund segregation, residual interest, regulatory capital, or NFA/CFTC reporting, plus familiarity with WinJammer and the NFA's online systems.
- Strong accounting and financial operations fundamentals, including general-ledger ownership, reconciliations, close, and audit readiness.
- A control mindset: you validate numbers, investigate breaks, document decisions, and never let unexplained differences roll forward.
- Ability to translate regulatory and accounting requirements into precise data and system requirements for engineers.
- Highly organized, self-directed, honest, and calm under pressure; able to lead across finance, compliance, legal, banking, and engineering with minimal oversight.
Nice To Haves
- Experience helping launch, register, or materially expand an FCM or other regulated market intermediary.
- Experience with institutional brokerage, crypto market infrastructure, or a technology-forward FCM.

- Experience managing external accountants, auditors, banks, or regulatory examinations.
- Strong AI tooling and automation skills (agents, assistants)
Responsibilities
- Own daily customer-funds segregation and secured-amount calculations, residual-interest monitoring, and capital, liquidity, customer-balance, and bank-balance controls.
- Prepare and oversee NFA and CFTC filings, including daily segregation reports, Form 1-FR-FCM, bi-monthly SIDR and recurring financial submissions.
- Build an audit-ready control environment with reconciliations, approvals, exception management, evidence retention, and clear operating procedures.
- Own the general ledger, month-end close, treasury, and banking operations, working with external accountants, auditors, and depositories.
- Translate finance and regulatory requirements into systems and automate reconciliations, reporting, controls, and data pipelines with engineering.
