We are backed by Lightspeed, Pantera Capital, Sino Global Capital, Blockchain.com Ventures, Avon Ventures by Fidelity Investments, DeFi Alliance and other top tier investors. We are run as a technology company, not a financial service provider, and we build our culture around core values of ambition, collaboration, entrepreneurship, transparency and meritocracy.

Working at Wintermute

We are looking for a Core Developer to work on building out an automated trade reconciliation system. This is a greenfield project and you will work closely with the Lead Core Developer, CTO, Middle Office Lead and traders.

The solution will match order and transfer information from the large number of crypto exchanges that we trade on to generate near-live middle office confirmations and reconciled positions, live alerts, and historic reports. We are a Linux based company and the solution will be built in Python and should “talk to” C++ stack. It is going to be a very high-performance solution that should be capable of reconciling up to 100M transactions a day.

The role is ideal for a candidate with strong Python skills who is interested to work on building new high-performance systems and developing their knowledge of system architecture, as well as of finance and trading. Crypto exchange experience is not required, but interest in financial and crypto markets would be an advantage.

Hard skills requirements

• 2+ experience of Python 3 (could be academic or personal projects) and having experience with C++ as a secondary language is an advantage


• Experience working with reconciliation, risk or other middle office systems would be an advantage, but not required


• Experience building/upgrading and using SQL based databases


• Familiarity with Linux, on desktops and servers


• Understanding of git or any other source versioning systems

Wintermute Offer

• A unique opportunity to work on very interesting projects, get the level of responsibility and ownership that would be unlikely at any other project or trading firm


• A unique opportunity to join one of the strongest and most successful technology teams globally


• Great company culture: informal, non-hierarchical, ambitious, highly professional yet collaborative and entrepreneurial  


• A cool office in central London


• Although we are unable to accept fully remote candidates, we support significant flexibility in regards to working from home and working hours.


• Aligned incentive structure: a significant part of your compensation is similar to that of owners - significant performance-based variable pay and the best thing - your contribution directly impacts both and the upside is unlimited


• We offer standard perks too, like pension, private health insurance and free food, but that’s probably not the right reason to join us


• We offer UK work permits and help in relocation

• Love coding, love problem solving, and love seeing your products work


• Love building things


• Are curious about algorithmic trading and financial markets


• Are determined, ambitious yet humble, willing to work hard and learn on the way

• Like working like an owner and not having a 9-to-5 or contractor mentality
