Working at Wintermute

We are looking for a C++ Quant Developer who is passionate about technology, interested in both low level details of how computer hardware operates and high-level design of large systems, as well as in data infrastructure. Someone who likes opening the hood to see how things work, has understanding of data structures, experience writing client-server network applications, and writing and optimising code for high performance. We welcome your previous experience from your own personal projects as well as commercial experience. PhD in maths is not uncommon for our Quant Developers, and at least a graduate level of maths skills is required. Interest in algorithmic and quantitative trading is a plus.
At Wintermute you will have an opportunity to grow and make direct impact on trading by developing and improving all the parts of the trading platform, data infrastructure and related software, while also getting advice and guidance from very experienced developers and traders, including the founders. You will get a lot of independence and responsibility right away, and you'll learn at an unprecedented speed! No legacy systems, no multiple levels of approvals, no bureaucracy; all developers report directly to CTO who is very hands on. It is up to you to make an impact! You will work alongside exceptionally sharp colleagues, learn how to write fail-safe code and improve performance and scalability of the trading system, a real challenge and a rare opportunity! We have flexible working arrangements, it’s the productivity that matters. At least several days a week in the office with our own gym, unlimited food and drinks are required.

What will you work on

A great advantage of this position is that it is varied, and it is also up to you to shape it in the direction that matches your talents and company needs. The focus of the role would be to create data infrastructure to bring the analytics to the next level and support the scaling of quantitative trading. Projects may also include upgrading major trading system components, designing a completely new application from scratch, working on implementation of pricing models. We will share more technical details in the interviews. You will have opportunity to improve your knowledge of software optimisations, of building robust large-scale systems and to understand crypto currency trading.
