Job description

Join the Wincent team, a high-frequency trading (HFT) company pioneering the crypto market since 2017. With algorithms operating on 13 exchanges and trading approximately 70 cryptocurrencies, we are a leading global market maker. At Wincent, we seek individuals with a competitive mindset, regardless of their level of interest in crypto. If you're driven by challenge and innovation and want to join a team shaping the future of trading, consider a career with Wincent.

Open positions

Our algorithms are only as effective as the individuals who develop and maintain them. That's why we're focused on building a team of highly skilled professionals from diverse backgrounds. We have engineers and researchers from Facebook and Google, with academic backgrounds from Berkeley, Caltech, ETH, and MIT. Additionally, our team includes international medalists from informatics, math, and physics olympiads, professional Go, Poker, and Chess players.

We trust each other.

No secrets; no bureaucracy; no committees. We hire smart people so they can do a great job based on smart information and not fight corporate politics. [*Almost. We of course respect personal privacy and GDPR.]

We say things as they are.

We have no tolerance for games of politics, fluff, or bullshit in general.

We leave our egos at the door.

At Wincent, we're all about teamwork and mutual respect.
