Discover your story with Adaptive. Senior or Principal Machine Learning Scientist Position Overview Adaptive Biotechnologies is seeking a Senior or Principal Machine Learning Scientist to join a team developing deep learning models for TCR-pMHC specificity prediction. This role focuses on predicting interactions between T cell receptors and peptide-MHC complexes by integrating sequence, structural, and large-scale biological data. In this role, you will work closely with computational scientists, immunologists, translational scientists, and machine learning engineers to build models that support Adaptive’s diagnostic and therapeutic initiatives. The work draws on a large and growing proprietary immune receptor dataset purpose-built for this machine learning problem, as well as shared GPU infrastructure and a close feedback loop between model development and experimental data generation. At the Senior level, the role emphasizes independent ownership of major modeling workstreams, rigorous technical execution, and strong cross-functional collaboration. At the Principal level, the role expands to broader technical leadership, modeling and data strategy, roadmap influence, and long-term direction setting across teams. Key Responsibilities and Essential Functions Design, implement, train, and evaluate deep learning models for TCR-pMHC specificity prediction. Integrate sequence, structural, and large-scale biological data into principled modeling approaches. Adapt advances in protein structure prediction, protein-protein interaction modeling, protein language models, representation learning, and related areas to immune receptor prediction. Develop rigorous benchmarking and evaluation strategies to assess model performance, generalization, and practical utility. Translate biological principles of T cell recognition into modeling decisions. Use model results to inform experimental data generation and identify opportunities to improve model performance. Partner with computational biology, immunology, translational, and engineering teams to ensure models are robust, reproducible, scalable, and aligned with product goals. Communicate modeling approaches, results, and limitations to scientific and technical audiences. Contribute to publications, presentations, intellectual property, and internal technical decision-making. Perform all other duties as assigned. Additional Expectations at the Principal Level Define modeling and data strategy across multiple workstreams or programs. Evaluate emerging machine learning advances and determine how they should shape Adaptive’s modeling roadmap. Set long-term technical direction for machine learning approaches in immune receptor specificity prediction. Influence organization-wide standards for model evaluation, benchmarking, reproducibility, and scientific rigor. Communicate complex modeling insights to scientific leadership, executives, and external partners. Mentor and influence scientists and engineers through technical leadership and strategic judgment.
