Applied Scientist, NLP​/IR​/GenAI

Overview

Join us in building Thomson Reuters' next-generation search platform that powers everything from direct user queries to GenAI applications across our product suite. We're creating a modular, state-of-the-art search infrastructure that will dramatically accelerate development timelines while elevating search quality company-wide.

As an Applied Scientist
, you will:

• Innovate: Design end-to-end AI solutions using information retrieval techniques, prompting workflows, and robust training/evaluation methodologies to optimize model performance and impact.

• Build & Deliver: Develop, test, and deploy live production systems in collaboration with engineering, ensuring well-managed software delivery and reliability at scale.

• Work Autonomously & With a Team: Solve problems in a self-directed manner while contributing effectively as part of a multidisciplinary team.

• Make Sound Technical Choices: Independently determine appropriate data, modeling approaches, and evaluation strategies for NLP and IR problems.

• Communicate & Align: Engage stakeholders to deeply understand business problems and domains, shaping objectives and goals that align AI technologies with product needs.

• Operationalize ML: Understand and inform MLOps processes for monitoring, evaluation, and retraining to maintain high-quality models in production.

• Advance the Field: Publish at top venues (e.g., NeurIPS, ACL, EMNLP, SIGIR) and contribute to patents to keep our solutions cutting-edge and competitive.

• Drive the design and delivery of AI capabilities that enhance Thomson Reuters' products and align with business objectives.

• Build and optimize models for NLP and IR applications, including transformer-based and LLM-driven approaches.

• Develop prompting workflows and evaluation designs to ensure reliability, quality, and continuous improvement.

• Partner closely with Engineering and Product to translate complex challenges into scalable, production-ready solutions.

• Define metrics and run experiments for model monitoring, evaluation, and retraining.

• PhD in Computer Science, AI, or a related field, or a Master's with equivalent research/industry experience.

• 3+ years of hands-on experience building and deploying deep learning models for NLP or IR applications.

• Expertise in large language models (LLMs).

• Strong programming skills (e.g., Python) and experience with modern ML frameworks (e.g., PyTorch, Tensor Flow).

• Proven ability to translate complex problems into innovative AI applications.

• Publications at relevant venues such as ACL, EMNLP, NAACL, NeurIPS, ICLR, SIGIR, or KDD.

• Solid understanding of classic ML techniques used for NLP problems.

• Solid understanding of deep learning approaches for NLP and IR (e.g., transformer-based models).

• Working understanding of the inner workings of large language models.

• Experience with text-heavy NLP projects.

• Practical experience with generative AI technologies (prompt engineering, in-context learning, chain-of-thought, prompt optimization, auto-evaluation, function calling, controlled generation, etc.).

• Practical experience with RAG frameworks, pre-training/fine-tuning language models, and data curation/generation for training and fine-tuning.

• Prior work on search and question answering over large corpora and/or long-document summarization.

• Experience building applications for the legal domain (e.g., document review, document drafting).

• Publications at relevant venues such as ACL, EMNLP, NAACL, NeurIPS, ICLR, SIGIR, ICML, KDD, or similar conferences and venues.

• Hybrid Work Model: We've adopted a flexible hybrid working environment (2-3 days a week in the office depending on the role) for our office-based roles while delivering a seamless experience that is digitally and physically connected.

• Flexibility & Work-Life Balance: Flex My Way is a set of supportive workplace policies designed to help manage personal and professional responsibilities, including work from anywhere for up to 8 weeks per year.

• Career Development and Growth: Our Grow My Way programming and skills-first approach ensures you have the tools and knowledge to grow, lead, and thrive in an AI-enabled future.

• Industry Competitive Benefits: We offer comprehensive benefit plans including flexible vacation, two company-wide Mental Health Days off, retirement savings, tuition reimbursement, and wellbeing resources.

• Culture: Globally recognized for inclusion and belonging, flexibility, work-life balance, and more. We live by our values:
  Obsess over our Customers, Compete to Win, Challenge (Y) our Thinking, Act Fast / Learn Fast, and Stronger Together.

• Social Impact: Two paid volunteer days off annually and opportunities to get involved with ESG initiatives.

• Making a Real-World Impact: We help customers pursue justice, truth, and transparency, upholding the rule of law and providing trusted information globally.
