You’ll be working within a team of highly skilled python developers and quants that love to build amazing things. I am looking for someone who is passionate about mathematics and python data science as well as building a business.

You will be a python quant technologist or mathematician motivated by what’s new to ensure you’re always ahead of the curve. You will understand the need and importance for zero downtime, secure and reliable backups and building maintainable one click solutions.

On a day to day you will:

  • Building a bigger team

    • Dimensionality Reduction
    • Projection into an information sphere
  • Designing and implementing a mechanism to make and track changes through time on the complex system

Python CTO’s MUST have: (the below also gives you an idea of stack)

  • Python development skills
  • Lead Development experience
  • MSc or BSc in Maths Stats or Comp Sci from a top school MIT Oxbridge or Imperial (Southampton Comp Sci)
  • Good understanding mathematics
  • GIT
  • Ideally noSQL or MySQL
  • Understanding of relational and non-relational databases with or without using an ORM
  • R or Matlab ideally
  • Interest in quantitative problems

The environment is that of Facebook or Google, relaxed open with time to think and make the right decisions. The atmosphere is calm and relaxed with an open dress code. This is a role for techies, those who are motivated by the sharp end of technology and the possibility of making serious money doing something you are passionate about.
My client is based in Oxford but are happy for people to only work a day a week from the office (travel to and from paid for)
If this sounds of interest then please apply directly.
