What is Slice?

Slice is the leading technology and marketing platform made exclusively for local pizzerias, making it super easy to order delicious, authentic local pizza anywhere, anytime. We serve the $44 billion U.S. pizzeria market in two ways: by providing a pizza-centric mobile and web ordering experience for consumers, and by empowering local restaurants with the technology, tools, and marketing to grow their business, while helping them compete with Big Pizza. Can you imagine what a small mom and pop pizza shop could achieve with the resources of Domino’s?

In this role, you will be one of the founding members of the Machine Learning Data Science team for our leading marketplace technology company. You will develop and implement machine learning algorithms and personalisation products from scratch that directly impact our customers. You will be partnering closely with our Product, Engineering and Business stakeholders to open up new opportunities and accelerate the growth of the business. Your strong foundations in mathematics, statistics and machine learning and exceptional communication and leadership skills will bring unique insights into our strategy. Your passion for solving problems and sense of urgency will fuel the success of the team.

We are open to applications from UK candidates who are interested in working on a permanent remote basis.

What you will be doing:

  • Develop ML models to derive insights on customer behaviour and inform product opportunities and strategy.
  • Partner with Product teams on developing product roadmaps and leveraging ML techniques to curate a better user experience and drive business results.
