Machine Learning Engineer

London, United Kingdom, Full Time >£40k

The Company

Founded by two machine learning experts (Cambridge PhD and Mila PhD) and a former industry executive, J2- Reliance is an R&D consultancy with an obsession for transforming data and technologies into business value. We are experts in identifying what and how cutting-edge technologies from various research fields can be leveraged to solve a hard business problem. We develop and deploy the corresponding solutions end-to-end.

In the retail space, we have successfully applied Language Modelling techniques (Transformers) to the development of powerful recommender systems, and we have built deep learning models for demand forecasting in complex business contexts. Building up on this success, we have been selected to be a strategic partner for a leading retail franchise with a three-year mandate to lead the AI strategy and developments centered on core missions: product recommendation, supply chain optimisation and pricing optimisation.

Outside the retail sector we are supporting multiple tech start-ups and leading Machine Learning projects in the pharmaceutical sector.

Who we are looking for

We are looking for talented engineers and applied scientists with an intense curiosity in Machine Learning and Computer Science and the will to solve concrete business problems in a different way. We value intellectually creative, bold, courageous, and self- demanding individuals from a wide variety of technical and scientific backgrounds.

The successful candidate will work on a diversity of projects within a long-term R&D mission for a leading retail brand concerned with the development of product recommendation, supply chain optimisation.
