## Job description

## About River Markets

River Markets is building the prime brokerage and execution layer for prediction markets: the infrastructure professional and institutional traders need to access, trade, and manage risk across venues such as Kalshi and Polymarket US at scale.

We started as two quants from HFT and hedge funds who traded prediction markets at night and on weekends, saw that institutional traders lacked a proper execution and financing layer, and built it. Today, we are connected to three exchanges, run six proprietary execution algorithms, and serve paying trading firms.

We value ownership, speed, precision, and a high technical bar. We are building a highly automated FCM and do more with a small team than a traditional financial institution would think possible.

How we work: AI-native, control first We use AI and automation across the company. For this role, automation must make the control environment stronger, not more opaque. We want someone who asks what can stop being done by hand, then designs the checks, documentation, and human review needed to trust the result.

## What you'll do

As our founding financial operations leader, you will build and own the finance function for our FCM, serve as an NFA-listed principal subject to approval, and work directly with founders, engineers, counsel, auditors, and advisers. Concretely, you will:

- 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.

## What we expect

- By month 1, map every finance and regulatory workflow, define owners and controls, and identify system gaps.
- By month 3, own the operating calendar for segregation, capital, treasury, close, and reporting.
- By month 6, run an accurate, audit-ready finance function that recovers cleanly from control or data-feed failures.

## What we're looking for

- 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.

Bonus

- 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.
- Strong skills in Excel, Python and SQL experience used to automate controls and reporting.
- Experience managing external accountants, auditors, banks, or regulatory examinations.
- Strong AI tooling and automation skills (agents, assistants)

## Compensation, Benefits & Perks

- Base salary: $140,000-$250,000
- Equity: 0.2%-0.5%
- On-site in the San Francisco Bay Area
- Platinum health insurance plan, with 100% of the premium covered
- Unlimited PTO, with a minimum of three weeks
- Food provided in the office
- Fresh fruit and snacks from farmers markets and local shops
- Monthly team activity
- 401(k) match, fully vested
- Visa sponsorship available

- **Founders**: Matt Johnson (CEO/Owner)

## Core Business
- Primary industry/industries: Software Development, Talent & Staffing, Technology Consulting

- Mission or purpose statement: "We complete work with purpose and precision. We lead with humility, drive, and wisdom. We take care of what is entrusted to us, including time, budget, relationships, and trust."

## Products & Services
- **Embedded Teams**: Top-tier talent that integrates seamlessly with a client's team, providing specialized expertise that scales with the vision while maintaining flexibility as priorities shift.
- **Scoped Projects**: Time-defined project teams with clear objectives and predictable costs, covering Discovery, MVPs, technical validation, brand development, and more.
- **Recruiting Services**: Full-cycle talent acquisition for direct placement, contract-to-hire, or embedded recruiters, finding hidden talent aligned with technical needs and company culture.

- **Growth Signals**: 38.3% LinkedIn follower growth (yearly); expanding headcount with 12 new hires in the last year; multiple office locations across the US and Brazil

## Competitive Advantages
- **Three-in-one model**: Unlike traditional staffing agencies focused solely on headcount, Midwestern offers embedded teams, scoped projects, and recruiting under one US contract, providing flexibility that rigid staffing models cannot match.

- **Senior leadership depth**: CTO, VP of Scoped, Director of Engineering, Design Director, and other experienced leaders ensure high-quality delivery.

## Strategic Focus
- Current priorities include scaling the embedded teams model for AI-era work, expanding into new markets (notably Brazil), and deepening partnerships with growth-stage tech companies.
- Emphasis on "flexible talent, global reach" — enabling clients to scale up or down easily without overcommitting.

- **Culture**: Values-driven environment emphasizing clear communication, reliable follow-through, and commitment to quality. The team operates with humility, drive, and wisdom.
- **Work model**: Hybrid/remote-friendly with offices in Joplin (HQ), Springfield, and Dayton, plus a distributed workforce in Brazil.
- **Notable perks**: Opportunity to work on impactful products that have raised over $450M; exposure to a wide range of clients from startups to Fortune 500; clear career progression paths.
- **Engineering culture**: 39% of staff are in technical roles (47 people), with strong seniority distribution (26% specialist, 16% other management, 12% manager, 9% senior). Team members come from diverse backgrounds including DevMountain, Jack Henry, Leggett & Platt, and Gloo.
- **Growth opportunities**: 11% yearly headcount growth indicates a scaling organization with upward mobility for high performers.
