Crypto Operations Associate

About Onyx.

Onyx is building the market for people who enjoy being right. Our consumer platform lets people take positions on what happens next across sports, prediction markets, crypto, financial markets, politics, culture, and real-world events.

More than one million users have already found Onyx. Now, we’re bringing that same energy into regulated financial markets through Onyx Predictions, a CFTC-registered introducing broker and NFA member.

In June 2026, we raised a $20 million Series A led by Payward, the parent company of Kraken, valuing Onyx at $220 million less than one year after emerging from beta. Our team comes from Jane Street, DraftKings, Robinhood, xAI, SIG, HRT, and Harvard.

We’re building Onyx in New York with a small team, serious momentum, and no interest in moving slowly. The product is live. The market is growing. The category is still ours to define.

The Role.

We’re looking for a Sports Market & Crypto Operations Associate to help keep Onyx’s sports prediction markets accurate, clear, and reliable from listing through settlement. You’ll work across live events, sports data, and market rules, and help ensure that settlements, payouts, and crypto transactions are reflected accurately in customer balances.

This role suits someone who knows sports, is comfortable tracing crypto transactions, and can make careful decisions under pressure.

 

What You’ll Own:

• Set up sports markets with clear terms that account for game conditions, player availability, and applicable rules.
• Help shape and prioritize coverage across major leagues and competitions, including pre-game and live markets, spreads, totals, player props, and futures.
• Monitor live events, data feeds, and sports news. Respond to injuries, lineup changes, trades, weather, and other developments that may require a market update, suspension, or clarification.
• Determine outcomes using official league data, box scores, and other verified sources. Apply market rules consistently and meet time-sensitive settlement windows.
• Resolve discrepancies across sports data sources and write clear, timely explanations of market terms and settlement decisions.
• Monitor crypto deposits, withdrawals, and payouts. Use block explorers and internal tools to trace delayed or failed transfers and escalate issues that affect customer balances.
• Reconcile market settlements, payouts, and customer balances against internal records and on-chain activity where applicable. Document discrepancies and follow them through resolution.
• Partner with Product and Engineering to improve sports data integrations, settlement workflows, and transaction monitoring.

What We’re Looking For:

• Strong knowledge of multiple sports, including league rules, playoff structures, tiebreakers, and statistical categories.
• Experience with sportsbooks, daily fantasy sports, trading, or prediction markets, including common market formats and settlement practices.
• Experience working with time-sensitive sports data and interpreting box scores, game situations, and official rulings.
• Sound judgment on settlement edge cases such as postponed or suspended games, stat corrections, and unusual scoring scenarios.
• Hands-on familiarity with crypto wallets, transaction hashes, network confirmations, and block explorers.
• Strong spreadsheet skills and the ability to compare records across systems and investigate discrepancies.
• Clear written communication, especially when explaining a settlement decision or handing off an unresolved issue.
• The ability to follow multiple live events, prioritize issues under pressure, and work evenings and weekends around the sports calendar.

Location:

• This role is based in our NoHo, Manhattan office, with core in-office days Tuesday through Thursday. The role may require additional coverage during major sporting events, market-moving news, and periods of high trading activity.
• Candidates must be authorized to work in the United States. Onyx is unable to provide employment sponsorship for this position.

Compensation and Benefits:

• The anticipated base salary range for this position is $80,000–$120,000, depending on experience, impact, and scope, plus a target bonus and equity.

Benefits include:

Why Onyx?

Onyx is for people with conviction.

We hire talented people, give them meaningful ownership, and expect them to use it. Our teams stay small, the work stays visible, and the distance between an idea and production stays short.

Onyx moves quickly because our markets move quickly. Titles matter less than judgment, initiative, and the quality of what you ship. Good ideas can come from anywhere, but the person willing to make the call is expected to follow it through.

We value people who are ambitious without ego, intellectually honest, comfortable with uncertainty, and energized by hard problems. We debate openly, decide quickly, and take responsibility for the result.

Come build what’s next with us.
