Principal Scientist, Machine Learning (Large Language Models)

The Role FL97 is seeking an experienced, creative, and talented Principal Scientist, ML (LLMs) to join our team. You will be part of an agile, cross-functional team responsible for training state-of-the-art, large-scale models on the scientific corpora, fine-tuning models with feedback (e.g. RLHF/DPO) and integrating multimodal scientific data. Together with biologists, bioinformaticians, software developers, and automation engineers, you will work on reimagining the way scientific research is conducted. The ideal candidate has a machine learning background, with previous experience building large-scale generative models, complex pre-processing pipelines, and comprehensive benchmarks to support scientific tasks. Mature software engineering skills and familiarity with best practices in software development are also highly desired. Candidates should have experience and/or interest in: Designing, training, and fine-tuning large language models (LLMs), including the ability to successfully adapt an LLM for use in a specific domain. Leveraging NLP tools to solve real world problems that require sequential decision making. Implementing rigorous testing, documentation, and model benchmarking. Qualifications: PhD in computer science, applied mathematics, physics, computational biology or other quantitative disciplines. 5+ years of experience in developing deep learning and/or NLP models. Contributions to research conferences or journals (e.g. NeurIPS, ICML, AAAI, ICLR) Expertise in at least one ML framework (PyTorch/TensorFlow/Jax) and robust experience in the Python data science ecosystem. Experience in training and deploying ML models on distributed computing services (g. AWS/GCP/Azure, or clusters). Bonus: Experience with knowledge graphs, prompting techniques (e.g., Chain-of-Thought), RAG, and/or autonomous agents. Bonus: Incorporating these models into AI-enabled toolchains for the biology lab. Working at FL97, you would have access to advanced technology in the areas of: AI experimental design and simulation Automated liquid handling and instrumentation Generative molecular design More About Flagship Pioneering Flagship Pioneering is a biotechnology company that invents and builds platform companies, each with the potential for multiple products that transform human health or sustainability.
