Responsibilities This role requires an experienced well-rounded Data Scientist who is able and willing to deeply understand problem domains and iterate quickly in the search for models that both solve stakeholder needs and fulfill technological best practices. Among the responsibilities:

  • Develop NLP models that accelerate the development of large foundational models and, with the help of a broader team, shepherd them into production;
  • Mentoring researchers and business stakeholders on best practices for data collection and fine tuning processes for LLMs and other Large Foundational Models;
  • Collaboratively build a well-considered experiment plan and document results carefully; patiently answer questions from technical and non-technical stakeholders;
  • Proactive requirements gathering from international stakeholders with diverse professional specialization;
  • Understand product requirements, drive clarity, and break down technical tasks into smaller units;
  • To work in a collaborative team of interdependent colleagues; to share code liberally; to scope and accomplish work according to a sprint cycle;
  • Support researchers and labeling staff to perform investigations when data-related problems arise;
  • Perform basic project management when delivering an ML solution for large, complex product teams; Qualifications We seek candidates with most or all of the following:

  • Intermediate-to-advanced experience with one or more subdomains of NLP, such as natural language understanding (NLU), document processing, information extraction, information retrieval, and dependency parsing; experience with multilingual NLP is “a plus”; hands-on experience fine-tuning encoder-only (e.g., BERT) or decoder-only (e.g., LLaMA) LLM also “a plus”;
  • Knowledge of ML fundamentals, including common algorithms in major paradigms (i.e., supervised, unsupervised, reinforcement), evaluation strategies, optimization (e.g., gradient descent, parameter tuning), and sampling;
  • Ability to research state-of-the-art algorithms and industry best practices, then apply them to problems at hand;
  • Excellent written and spoken communication skills for the purpose of communicating with business stakeholders and international teams;
  • Advanced skills in Python;
  • Advanced skills in SQL, databases, and general data modeling;
  • Experience deploying ML models “at scale” and ability to reason about trade-offs (hardware, volume, velocity, model size, etc.);
  • Knowledge of and experience with “full stack” development, including writing backend API, modifying frontend clients, troubleshooting bottlenecks, and model hosting;
  • Experience with active learning and human-in-the-loop ML “a plus”;
  • Experience with experiment design “a plus”;
  • Ability and willingness to partake in product design is “a plus”;
  • Project management experience is “a plus” 【For Pay Transparency】Compensation Description (annually) The base salary range for this position in the selected city is $144000 - $312000 annually.​

What is NLP?

What is NLP?

Natural language processing What is natural language processing? Natural language processing, or NLP, is a field of artificial intelligence that focuses on the interaction between computers and humans using natural language. NLP is a branch of AI but is really a mixture of disciplines such as linguistics, computer science, and engineering. There are a number of approaches to NLP, ranging from rule-based modelling of human language to statistical methods. Common uses of NLP include speech recognition systems, the voice assistants available on smartphones, and chatbots.
