Crypto quant trading firms: Wintermute, Jump Crypto, Cumberland, GSR and the traditional shops moving in

In UK accounts for 2024, a crypto market maker with 82 staff paid its people more on average than Hudson River Trading or Jump Trading did in London. In the same few years, crypto trading firms lived through a $160m hack, an exchange collapse, SEC lawsuits and a single day with roughly $20bn of forced liquidations. That combination of high pay and unusual risk is the whole story of crypto quant trading, and it is worth understanding before you take an offer from one of these desks.

Two kinds of firm

The sector splits roughly in two.

Crypto-native trading firms were built for digital assets:

• Wintermute was founded in London in 2017 by Evgeny Gaevoy, Harro Mantel and Yoann Turpin, all formerly of Optiver, where Gaevoy ran the ETF business. (Reported, eFinancialCareers, 2018.) The group says it facilitates over $10 billion in average daily volume across more than 60 centralized and decentralized exchanges. (Official, August 2026.)
• GSR describes "over a decade of expertise at the heart of crypto markets" and lists FCA registration in the UK and a Major Payment Institution license in Singapore. Its chairman spent nine years as a commodities trader at Goldman Sachs. (Official, 2026.)
• B2C2, another London-based liquidity provider, more than doubled its headcount in 2021 by hiring 64 people. (Reported, eFinancialCareers, November 2021.)

Crypto arms of traditional quant firms sit inside much larger businesses:

• Cumberland, part of DRW, offers OTC spot liquidity "in dozens of cryptocurrencies", listed options and futures, and bilateral options and forwards. DRW says it has been "at the forefront of crypto asset trading since 2014". (Official, 2026.)
• Jump Crypto, the crypto division of Jump Trading Group, began "as a skunkworks intern project in late 2015", according to Jump's job ads (official, Jump Trading job ads, 2026). Its own site describes the team as "builders of blockchain technology". (Official, 2026.)
• Jane Street set up a crypto trading desk in 2017. (Reported, eFinancialCareers, 2022.) Its own overview page does not mention crypto.
• Flow Traders lists digital asset ETPs, futures, spot and options among its markets. (Official, 2026.)

How the work differs

The core job, quoting two-sided prices and managing inventory, is the same market-making problem as in equities or options. What changes is the environment around it.

The market never closes. The SEC's October 2024 press release said Cumberland "operates 24 hours a day, seven days a week" by phone and through its online platform. (Official, SEC, October 2024.) A B2C2 options quant trader said the firm's traders work in shifts across London, Tokyo and Jersey City; she started around 7:30 to 8am and usually stopped around 7pm, sometimes working until 10pm or midnight. (Reported, eFinancialCareers, May 2022.)

Venues are fragmented and partly on-chain. Liquidity sits across dozens of centralized exchanges plus decentralized protocols, which is why Wintermute counts its venues in the dozens. One crypto fund CEO argued the asymmetry cuts both ways: "everything's in the open, so you can extract information", but "the infrastructure is so much slower". (Reported, eFinancialCareers, October 2023.)

The skill set is wider. A Jump Crypto trader ad in Singapore asks for Python, Linux and an "understanding of the various currencies, exchanges". Its London campus crypto researcher ad goes much further: distributed systems, consensus algorithms, networking and game theory. (Official job ads, live 2026-10-04.) A Blind user reposting a Wintermute graduate DeFi algorithmic trader ad listed Python, Rust or Go, HFT strategy knowledge, EVM fundamentals and smart contracts. (Self-reported, Blind, September 2025.)

In practice: a crypto quant interview still tests probability, statistics and market-making intuition, but DeFi-facing roles can add protocol mechanics that no equities desk would ask about.

Pay: what the filings and self-reports show

UK firms must file headcount and staff costs with Companies House. eFinancialCareers compiled average pay per employee for 20 electronic trading firms in London, mostly for years ending December 2024. The table below is a selection of 9 of those 20 firms, including the top four:

(Reported, eFinancialCareers, March 2026, from Companies House filings.) Quadrature Capital was the clear outlier at the top, at more than three times the next firm, and Wintermute ranked fifth of the 20. These averages include every employee, from traders to operations, and are skewed by small headcounts and a few very large payouts. They say nothing about what a graduate will earn. eFinancialCareers reports that Jane Street pay was on track to rise sharply in 2025, after the period shown.

Self-reported data points the same way. Levels.fyi shows a median total compensation of about £281,000 for Wintermute software engineers in the UK, based on a small number of self-reported submissions (Levels.fyi lists 14 for Wintermute software engineers). (Self-reported, Levels.fyi, accessed 2026-10-04.) A sample that small is a hint at best.

Pay timing can differ too. GSR advertises "two discretionary bonus payments a year". (Official, 2026.) A headhunter told eFinancialCareers in 2021 that crypto market makers "pay at least twice a year, and often monthly". (Reported, November 2021.) More frequent bonuses mean less deferred pay keeping you in your seat, which is attractive in a volatile sector.

The candidate view is mixed. One 2025 Blind post said opinions on Wintermute ranged from "high TC, great culture" to "dumpster fire". (Self-reported, Blind, March 2025, anonymous.) On whether crypto is a career risk, one reply in a 2024 thread argued "the methods of quant analysis don't change fundamentally for different kinds of assets aside from some domain specific stuff". (Self-reported, Blind, October 2024.)

The events that shaped the sector

Three themes run through that list.

Counterparty and operational risk. In exchange-traded traditional markets, a clearing house stands between you and a failing counterparty. In crypto, firms have held assets on exchanges like FTX and on smart contracts that can be exploited.

Market structure risk. On 10 October 2025, exchange auto-deleveraging closed market makers' short futures hedges, leaving them "holding naked spot bags in a free-falling market", according to BitMEX. (Reported, CoinDesk, January 2026.) Bitcoin order book depth within 1% of mid fell about a third, from roughly $20m to $14m, by mid-November. (Reported, CoinDesk, November 2025.)

Regulatory and legal risk. Enforcement swung with US policy: the SEC sued Cumberland in October 2024 and the case was dismissed in March 2025, with the SEC saying the move reflected its effort to "reform and renew its regulatory approach" rather than a view on the merits. (Reported, TheStreet, March 2025.) Jane Street denies the Terraform claims and calls them an attempt to "extract cash" over "a fraud that Terraform itself perpetrated"; it moved to dismiss in April 2026. (Reported, TheStreet, April 2026.) As of 2026-10-04, no ruling on that motion had been reported. Treat these as allegations.

The convergence

The line between "crypto firm" and "trading firm" is blurring from both sides.

Traditional firms are leaning in. Jane Street, which eFinancialCareers says retreated after FTX, reportedly tripled its crypto trading volumes in 2024, buying $110bn of crypto including stablecoins (reported, eFinancialCareers citing The Information, October 2025). The same piece says Citadel Securities is reportedly building crypto market-making teams. Digital assets went from 7% of Flow Traders' group revenue in 2019 to 24% in Q1 2026 (reported, Traders Magazine, July 2026), and the firm set a goal of being the "24/7 liquidity provider of choice" by 2030. (Official, Flow Traders, June 2026.)

Crypto-native firms are moving the other way. Wintermute USA can now trade equities and equity options and act as an authorized participant for digital asset ETPs. (Official, August 2026.) Coverage of the WSJ's reporting says Wintermute aims to compete with Jump, Jane Street and Citadel Securities within three to five years. (Reported, BeInCrypto, August 2026.) GSR now runs an ETF, the GSR Crypto Core3 ETF. (Official, 2026.)

Should you work in crypto quant trading?

A fair summary:

• Pay varies widely. In 2024 UK filings, one crypto-native firm (Wintermute) paid close to Citadel Securities and Jane Street on average, though far below the top payer, Quadrature; others, such as GSR, paid well below the leading traditional shops. Bonuses may arrive more often.
• Risk is wider: hacks, venue failures, 24/7 markets and shifting regulation are core parts of the job.
• Skills transfer both ways for core trading and research. Protocol-specific knowledge mostly matters for DeFi roles.
• Firm choice matters more than the label. A crypto desk inside DRW or Jump comes with a parent's infrastructure and balance sheet. A crypto-native firm gives you more scope, with more concentrated risk.

Interviews at both kinds of firm lean on the same core: probability, expected value and quoting under uncertainty. Our market-making game practices the quoting part, and our guide to quant roles by asset class compares crypto desks with equities, options and rates.
