Job Description

Summary

This is a superb opportunity for a proactive and pragmatic engineer to join an award-winning, tech-savvy algorithmic trading firm in London. You will be part of the team that builds software for their research cluster - one of the largest in the world, and still growing.

Based in London, they are looking to expand their exchange trading development team with a developer well-versed in modern C++ (C++11 onwards). This role has a company-wide impact, where everything the team builds is used in-house on one of the world's biggest trading systems (~$300bn/day), all in a completely automated manner.

This role offers a high degree of autonomy, giving you the authority to meet business requirements in the manner and using the software/tools that you see fit. If this approach appeals to you, please get in touch!

Requirements
  • Strong knowledge of C++11 onwards (they have a completely post-2011 codebase)
  • Sound understanding of what happens inside a computer when your code is running, e.g. caching, paging & system calls, how these work and why. (Knowledge of execution pipeline in a modern CPU is a bonus.)
  • Familiarity with common algorithms and data structures and their performance trade-offs
  • Practical experience of independently designing and implementing complex software systems is a plus
  • Experience with Linux is a plus (theirs is a Linux environment), but by no means a necessity
  • Financial experience is not required

Benefits
  • Competitive compensation package
  • Challenging work within a truly flat structure; ideas from everyone are encouraged and evaluated
  • Very direct impact on the PnL, with very little bureaucracy
  • Generous benefits package, including extensive medical & wellbeing provision, pension, onsite gym & sauna, fitness classes and regular staff social events


Whilst we carefully review all applications, to all jobs, due to the high volume of applications we receive it is not possible to respond to those who have not been successful.
