We’re looking for a senior data scientist who is passionate about making a positive difference in the world.

  • London

1 The Problem

Type 2 diabetes and obesity are huge problems, both for the millions of people that suffer from lifestyle diseases, as well as healthcare systems like the NHS.

In the UK we spend almost 10% of the NHS budget on treating type 2 diabetes alone (£9 billion/year). What’s shocking is almost all of this is avoidable, 80-90% in fact.

How? Through sustained lifestyle and weight loss. It sounds so simple, but in reality is much harder to achieve at scale.

2 OurPath

OurPath provide a digital lifestyle improvement programme that is proven to help people improve their lifestyle and lose weight, which ultimately reduces their risk for conditions such as type 2 diabetes.

The programme incorporates evidence-based education, health coaches, peer group support, and digital tracking tools. Everything is delivered digitally through phone and web apps.

The quickest way to understand what we do is watch this very short 1 min animation: https://vimeo.com/199648301

We were the first digital behavioural change programme to be commissioned by the NHS – we’re now expanding rapidly having won a few big national contracts (both in diabetes prevention and management).

Alongside our NHS work, we also offer the programme directly to consumers – you can buy the programme on our website if you’re looking to make a healthy lifestyle change and lose weight. Our direct-to-consumer channel is essentially a competitor to the likes of Weight Watchers and Slimming World.

About us: We are now a team of 50 – consisting of ex-strategy consultants, dietitians, designers, and developers. We believe OurPath is a fun place to work with an informal, non-bureaucratic, and agile working environment. Finally, we will provide endless amounts of poor jokes and sub-standard humour. Just so you know.
