About Smarkets

The Smarkets exchange is a multi-billion pound trading platform with a rapidly growing ecosystem of sophisticated users who apply financial trading techniques to the world of betting. We’re looking for a Quantitative Developer to join our Market Making group.

Our stack is consists of dockerized applications deployed on AWS. Our code is mostly Python with Rust used for performance critical components. We embrace the modern devops culture, practising continuous integration and deploying to production multiple times a day.

An Example project for the team:

"We are pricing lots of football leagues, some of which we know nothing about.  There is a nice market making algorithm to price them, and reacts to trades in a way that is consistent across various markets (match winner, both teams to score, over/under etc.). I worked on a project to implement this algorithm in a proper way, starting from a "back of the envelope" prototype of it.

The work involved reading a mathematical paper about the algorithm, finding problems with the initial implementation and rewriting a large portion it to use faster data structures.  Both of us wrote code, studied the theory, and analysed the speed and profitability of the algorithm in production. If an outsider looked at us working together, they wouldn't know who is the quant and who is the engineer.

An interesting part of the project was changing a data structure from dictionary to a Numpy array, which allowed us to change a summation in a nested loop into a single matrix multiplication. This made the code much simpler and faster." 


We are looking for a Quant Developer who will be working on the following key areas for the team:

  • Implementing, backtesting, shipping and monitoring data-based algorithms
  • Improving our technical and fundamental market models
  • Working to analyse market patterns
  • Defining your role in the context of self management (we'll help you with this)


  • Bachelor's degree in Computer Science, Mathematics, Physics or similar STEM subject.
  • 2 years or more experience in building quantitatively driven applications
  • Some knowledge in statistics, econometrics or statistical learning
  • Strong coding, being able to write efficient and performant code in any OO or Functional language
  • Database querying knowledge (PostgreSQL)

Desirable attributes

  • Experience working in a trading environment
  • Functional programming experience


  • Self-management structure similar to Valve
  • Unlimited holiday policies
  • Flexible and collaborative work environment
  • Daily catered meals (breakfast, lunch and dinner), free drinks and food all day, parties on a frequent basis
  • Work with one of Europe’s smartest workforces
