About the Role

It is an exciting place to be and allows us to provide unique insights about the business, its environment and the marketplace. As a predictor and forecaster of the future, it also is undoubtedly a valued and significant role.

The ideal candidate will have a strong quantitative or technical background with experience working with large datasets and solving tough problems. You will be a highly intelligent self-starter, with a bias towards action and attention to detail, reporting to the Data Science Manager.

Who are we looking for?

We are looking for a excited Full Stack Data Scientist who is happy to play across the data spectrum - of data engineering, data science and eventually a bit of data translation of insights to English.

A mid to well experienced Data Science practitioner who has done their time in the dark deep mines of data, built live production-ready algorithms at scale and most importantly has a passion for enabling data driven decision making for the wider business through the art of data empathy. This role will work on some cutting-edge data platforms and algorithms, with a unquenchable need to get things done!

What will you be doing?

At GFG, we’d like to think of our Data Scientist as a builder-at-heart doing all of the three functions described below. Each aspect broadly covers your day to day work, as well as how it serves the company needs. These three pillars serve to act as the cornerstones of this senior role.

This is quite a unique role and one that opens up opportunities to work across the cross section of the business as the key stakeholder of data driven decision making in these areas.

You’ll be the key owner of diverse areas using data ranging from Category Management team buying and planning merchandising, to the Fulfilment Center optimising every single inch of warehouse usage, to the Finance team finding the smartest way to forecast demand and supply, to the Customer Support team enabling our agents to deliver amazing customer service, and a few more that directly enable our employees to make smarter, faster and better decisions - which in turn leads us to be an amazing customer-focussed company.


  • Design and build some of the most novel yet extremely practical/actionable algorithms and data science applications - e.g. Real time personalisation, sku assortment algorithms
  • Redesign robust forecasting and predictive techniques to be able to get a closer-to-reality version of the future - e.g. Returns Forecasting, Propensity and churn models
  • Inculcate a Developer mindset to the application of data science in everyday business by practicing and preaching a reproducible, defensible and accuracy-driven approach


  • Identify automated and smarter ways of measuring changes in key metrics across the business along with a preemptive “why” to justify those changes - e.g. increase in app $
  • Enable the larger business and also other analysts to think of easier and more efficient ways of measuring success and being more experimental - e.g. generalising A/B Testing
  • Seek out and validate opportunities for new business growth by overlaying macro/external indicators on the top of our immense and rich in-house datasets


  • Translate math to business in an effective fashion, so as to enable key stakeholders to make quicker and accurate decisions without being bogged down by numbers/graphs
  • Train and guide junior analysts to upskill and enable them to work on more comprehensive and finer analysis, and lightening their workloads
  • Be able to continuously self-educate and seek out new avenues to learn the ever advancing world of data science

How will you be doing it?

With a confidence interval of 90%, if you can ‘strictly’ prove your skills in at least 4 of the 5, then you can easily be able to do most of what is stated above.

  • Language - Proficient and well-defined knowledge of at least 1 statistical programming language - R or Python AND the one main data language - SQL
  • Data - Ability to work with datasets of all shapes, sizes and textures - from 20 KB-200 PB

  • Maths - Proficient knowledge of statistics with a well displayed ability to build predictive models, forecasting approaches, simulation and personalisation algorithms

The zeroth skill that is expected as a default is an ability to program/code, along with the must-have skills of maintaining code quality and following standard software development life cycle of build -> test -> deploy using Git and a CI pipeline.
