As an Adapter, you’ll have the opportunity to make a difference in people’s lives. With Adaptive, you’ll create a career highlight through collaboration with bright, curious colleagues working at the apex of innovation and application. It’s time for your next chapter. Discover your story with Adaptive. Position Overview Adaptive Biotechnologies is seeking a Senior Machine Learning Scientist to contribute to the development of models for TCR–pMHC specificity prediction. In this role, you will design, implement, train, and evaluate models that predict interactions between T cell receptors and peptide–MHC complexes, with a focus on integrating sequence and structural information. Working as part of a collaborative modeling team, you will implement new modeling ideas, rigorously test their performance, and iterate quickly to improve predictive accuracy. This work leverages large-scale proprietary immune receptor datasets and shared GPU infrastructure to support rapid experimentation and model development. You will work closely with computational scientists, immunologists, and machine learning engineers across the organization. The team combines expertise in immune biology, experimental assay development, and large-scale machine learning, enabling a tight feedback loop between model development and experimental data generation. Model outputs often highlight gaps in available data or suggest new experimental directions, while newly generated datasets provide additional signal for improving and validating predictive models. Models developed in this role contribute directly to diagnostic and therapeutic initiatives both within Adaptive and through external partnerships. This role is well suited for a hands-on scientist who thrives in a collaborative environment and is motivated to translate cutting-edge machine learning into meaningful biological and clinical impact. Key Responsibilities and Essential Functions Design, implement, train, and iterate on novel deep learning models for TCR–pMHC specificity prediction. Adapt and extend advances in protein structure prediction and protein-protein interaction modeling to the immune receptor setting. Conduct rigorous benchmarking and evaluation strategies to ensure models are scientifically sound and practically superior. Translate biological principles of T cell recognition into principled modeling decisions. Influence large-scale experimental data generation to maximize modeling leverage and long-term performance gains. Provide technical recommendations to broader modeling discussions and roadmap planning. Work closely with computational biology, immunology, translational, and engineering teams to ensure models are robust, reproducible, and aligned with overall product goals. Communicate modeling insights, approaches, and results to cross-functional scientific audiences. Contribute to publications, presentations, etc. through technical execution and analysis. All other duties as assigned. Position Requirements Required PhD in a quantitative discipline (e.g. Machine Learning, Computational Biology, Computer Science, etc.) + 5 years progressive experience applying machine learning to real-world scientific or biological problems OR equivalent combination of education and experience. Progressive experience in the development and deployment of deep learning methods Strong hands-on experience in python and modern ML tooling (PyTorch preferred) Strong experience in deep learning architecture design and implementation. Strong experience with protein structure prediction or analysis Experience working with large datasets and high-performance computing environments Ability to independently define, scope, and execute complex technical research problems. Strong written and verbal communication skills, with ability to present hig…
