Job Description

Lead NLP Research Scientist

Lead Research Scientist who will work as part of the Nielsen Connect AI NLP Research Team.

The mission of the NLP (Natural Language Processing) Research Team is to Research, Develop and Deliver machine learning solutions that extract meaning and automate decision making from unstructured text and multi-modal data. Its aim is to provide our clients with higher quality, more timely and far reaching understanding of markets and consumers through the application of NLP.

You are an expert in applying NLP and machine learning to a wide range of business problems, and have proven experience with researching and deploying machine learning models applied to text data. We operate at scale, so you should be able to build models that can handle large, sparse and long tail datasets across multiple countries, categories and languages.

This role is responsible for the research and development of machine learning models to generate structured product attributes from ecommerce product data. You are an innovator at heart who is motivated by being set a challenging problem and can work as part of a close-knit team to invent cutting edge solutions which make a real difference to the business. You will not be afraid to learn and apply new techniques to solve a problem. You should have knowledge of and interest in the latest research and advancements in NLP, and, crucially, understand how to “take them out of the lab” to move beyond research to practical application.

Responsibilities
Develop machine learning models to perform product data attribution from text and image
Perform feasibility studies and analyse large amounts of data
Work with internal business stakeholders to understand operational processes and requirements and translate into data driven solutions.
Research and develop machine learning models and algorithms which can solve defined business objectives to agreed success criteria
Apply rapid prototyping agile principles to quickly move models from research to scalable data products to be tested with end users
Design experiments to measure the impact on productivity of developed models
Document results and present findings to stakeholders across the business
Work as part of the wider NLP Research team, contributing to cross-project research and development of a shared research code framework
