About the role

  • Lead the design, implementation, and execution of robust frameworks to evaluate the performance of generative AI systems, including text and multi-modal models.
  • Establish and refine metrics and benchmarks for model quality, including output fidelity, diversity, creativity, and bias detection.
  • Perform technical AI evaluations, benchmarking and “red-team” tests on large language models, including assessing them for robustness in performance, embedded biases, vulnerability to jailbreaks and prompt injection attacks.
  • Work with clients and more junior team members to design custom evaluation approaches using the latest scientific research that address the client’s needs.
  • Work with the product management team to develop a suite of technical and analytical AI evaluation frameworks and tools that are backed by scientific research and methods.
  • Lead the design and implementation of evaluation frameworks for Large Language Models (LLMs), including but not limited to GPT-based models, BERT, T5, and other state-of-the-art architectures.
  • Define and refine metrics for evaluating model performance, such as perplexity, BLEU, ROUGE, accuracy, coherence, factual consistency, and bias detection.
  • Lead efforts in curating and managing large, high-quality datasets for evaluating LLMs, ensuring data is representative, unbiased, and ethically sourced.
  • Mentor junior data scientists, guiding them in best practices for LLM evaluation and the latest advancements in NLP.
  • Stay up-to-date with the latest advancements in Natural Language Processing (NLP) and LLM evaluation, applying cutting-edge methods and tools to improve model performance.

Requirements

  • Extensive experience as a data scientist training or deploying deep learning based natural language models/large language models in real-world contexts.
  • About 5-8 years of working experience or a relevant postgraduate degree with 2+ years of working experience building and deploying LLMs.
  • Strong experience in evaluating LLMs using metrics such as perplexity, BLEU, ROUGE, and human-centered evaluation techniques.
  • Proven track record of managing and analyzing large, complex language datasets, including text preprocessing and tokenization.
  • Excellent written and verbal communication skills, with the ability to clearly explain complex technical concepts to diverse audiences, including non-technical stakeholders.
  • Solid programming skills in Python and experience building automated pipelines for continuous model evaluation.
  • Passion and interest in applied research on the safe and responsible use of AI and with large language models.
  • NICE TO HAVE: Published research in the field of generative AI or model evaluation.
  • Hands-on experience with model explainability tools and methods.
  • Familiarity with cloud-based platforms (e.g., AWS, GCP) for scalable model evaluation and deployment.
