Xanadu Trading is a young knowledge and technology based proprietary trading start-up. We are active in one of the most intense industries in the world. We trade our own capital, for our own risk and benefit, and have no customers. Xanadu is focused on high frequency algorithmic black box futures trading as well grey box options market making on Eurex, LIFFE and CME. We have offices in both London and Barcelona.

Options market making software needs to be at the same time very fast and responsive as well as reliable and bug-free. This is what has made developing in this area one of the most challenging, difficult and interesting propositions around. Xanadu's young technology department not only aims to compete in this area, but to disrupt it - from (almost) scratch, and with less man power than most competitors. And in order to do so, we are looking for great technologists.


As ideal candidate you

  • are passionate about technology: You might compile your own operating system, you might write your own personal Android apps, lead or contribute to open source projects, run a technology blog, maintain a public library, collect stackoverflow points or anything similar. You view programming languages as a way of expressing yourself, and are open to pick the best one for each task at hand. You handle several scripting languages, because you'd rather learn something new than repeat a task 20 times. You love gadgets. You love unwrapping stuff. And most of all, you love clean code. Xanadu loves clean code. We are all about clean code. There is little else as beautiful.
  • are smart: You learn quickly. You want to be challenged. You want to achieve. You want to grow. You want responsibility. You want to take it up against the rest of the world. Then we want you. We are looking for anything that portrays excellence. Grades, projects, hackathons, you name it.
  • are disciplined: You can finish what you start. We are still a young and small company, and in this environment you are given a lot of freedom and responsibility. You enjoy this and can handle the implications. You can self motivate. You can stick to deadlines. And you don't compromise on quality to do so. Ever.
  • excel in C++: For the first year, you will be working on a C++ project at the heart of our trading software. As such, outstanding C++ proficiency and experience are essential. While requirements change, years end, and you should be open to other technologies, most of our software is C++ and Java based - and will likely remain so. Experience in low latency systems and exchange feeds is advantageous.
  • like start-up culture: Xanadu is young, small, dynamic and non-corporate. We only just opened our office in Barcelona, and as one of our first employees here you would have considerable influence on shaping the company and in helping it realize its vision. You would assume a lot of responsibility very quickly, have a very steep learning curve and the potential to grow into a leadership role as early as 2018.
  • speak English: we are an English speaking company - Spanish is not required.
  • have development experience in a Linux/UNIX environment.
  • know about algorithms, data structures, threading and design patterns.
  • are interested in the financial markets.
  • have a degree with an analytical/quantitative field of study (engineering, computer science, math, statistics, physics, etc.).


At Xanadu, coding is at the heart of what we do - and we strive to make coding here innovative, pragmatic and fun. And although we are a trading company, we are much closer to a technology company than most trading companies - think university research department, rather than trading floor. In general, you will find (semi) private offices and quietness. Of course, private offices don't always make sense, and for certain roles we prefer shared spaces. We strongly believe in flow work - we offer a quiet environment, non-disturb hours (no meetings, no phone, closed doors, limited knocking and email), quick compile cycles, we subscribe and support most developers bill of rights (such as The Programmer's Bill of Rights), we try to maximize your control over your personal workspace, provide food and entertainment and to generally remove any obstacles you might face. Our salaries are competitive. We dress casually.
