We’re looking for an intellectually curious, humble, ambitious and razor-sharp Data Scientists with varying levels of industry experience. You are someone who is passionate about technology and, even more so, about applying data science, machine learning and artificial intelligence technologies more broadly to real-world problems. We embrace those who see things differently, aren’t afraid to experiment, and who have a healthy disregard for constraints. The ideal candidate must be a master of their domain and should be skilled at taking ambiguous business or product requirements, translating them into hypotheses, finding the right solution, prototyping their ideas and productionise their work. This individual will be fundamentally motivated by wanting to drive significant business impact through the application of their knowledge and skills. Furthermore, the ideal candidate should be able to inspire and champion through influence when the need arises. We are looking for a rare mix of intelligence, integrity, domain knowledge, verbal agility, and diplomacy which allows you to rapidly earn the trust of technically astute engineers and product astute product management leaders.

Why We Need This Role

Our data scientists will be a part of the Intelligent Systems based in London/France but will work closely and collaborate with global product and engineering teams across 3 locations: London, New Delhi and Los Angeles. The Intelligent Systems team manages all of the innovation powered by data science, machine learning and AI (decision making). It is likely to witness significant growth over the course of the next year and beyond.

This team will take ownership of a whole host of different existing use cases and there is also a significant potential to test out ideas that currently are in the pure research domain. Key problems include:

  1. Automatic speech to text transcription of audio calls between customers, partners and colleagues.
  2. Extracting features and other informative entities from call transcription and documents.
  3. Recommending app templates based on customer’s ideas and requirements.
  4. Recommending features for apps based on customer’s description of requirements.
  5. Engaging customers and colleagues in conversation using chatbots/conversational AI to gather requirements, create buildcards, and keep them updated on project progress.
  6. Building custom speech recognition models to improve accuracy of speech transcriptions.
  7. Building custom language models to better understand the semantics in the Builder domain.
  8. Build models to pick customer questions and answer them automatically to create better engagement.

We are looking to expand the IS-NLP team who owns the NLP services like Template recommendation, Feature Search, Story Similarity, Feature Tagging, and Natasha. As we look to expand our service portfolio to efficiently automate Builder delivery processes, we are keen to expand the team to support our ambitions.
