The Machine Learning team at OpenTable has two opposing challenges that manifest themselves as opportunities:OpenTable is the world's leading provider of online restaurant reservations, seating more than 25 million diners per month via online bookings across approximately 60,000 restaurants. It has an extensive wealth of diner and restaurant data going back over 20 years.OpenTable fields a lean team, with just over 1,000 employees globally. We currently have a team of 15 people, but aspiring to grow.As a member of the team, you will benefit from these factors because your projects will have sufficient data and usage to be interesting and have a meaningful impact, and you will have the opportunity to work on a variety of exciting projects across the company. However, you will be required to think critically and ruthlessly prioritize, since the team has finite bandwidth. If these challenges sound appealing, then we look forward to hearing from you!OpenTable strives to provide a fair, collaborative, and balanced work environment.Unfortunately, we do not provide visa sponsorship.In this role, you will: Our team is looking for someone passionate about Natural Language Processing. You will be working within a team of scientists and engineers that leverage NLP to improve the quality of OpenTable product. Conduct research and development of Natural Language Processing (NLP) models, and collaborate with engineers to bring these models into production. The responsibilities include, but are not limited to:Utilizing prompt engineering and parameter-efficient fine-tuning methods to enhance the performance of Large Language Models (LLMs) for a specific task.Constructing data pipelines essential for the training and evaluation of NLP models.Implementing comprehensive evaluation suites for measuring and assessing the performance and safety of models on a specific task.Develop applications that utilize large language models (LLMs), enhancing their capabilities through RAG and through incorporation of different Tools.Contribute to the internal ML packages, and help the team to build tools for training, evaluating, debugging, and interpreting NLP models for retrieval, reranking and generation.Stay current with NLP research, know when to apply it to your work, and how to communicate it to your partners.
