We9re looking for a motivated and creative
Machine Learning (ML) Scientist to drive research into biomolecular structure prediction. You will build and improve all-atom co-folding models, with a focus on the complexes that matter most to our programs: antibody-antigen interfaces and protein-nucleic acid assemblies. These remain among the hardest cases for current models, and closing that gap directly accelerates our antibody design and genome editing work.
The ideal candidate has trained structure prediction models at a leading academic or industry lab and knows where today9s models break. You will be a self-directed researcher who moves quickly from hypothesis to trained model to rigorous evaluation. As an early member of the ML team, you will help shape how structure modeling fits alongside our generative models (ProGen3, E1) and experimental platforms.
Responsibilities- Develop and train all-atom structure prediction models, improving accuracy on antibody-antigen and protein-nucleic acid complexes
- Diagnose failure modes of current models (e.g., CDR-H3 and epitope placement, interface geometry, nucleic acid conformations, confidence calibration) and design architecture, training, and data interventions to address them
- Curate large-scale training data from structural databases, distillation sets, and Profluent9s own experimental binding and function data
- Integrate structure models with our generative models for design and filtering, and work with protein design teams on experimental validation
- Present results to colleagues in regular update meetings
Qualifications- PhD (or equivalent industry experience) in computer science, computational biology, biophysics, or a related field
- Hands-on experience building and training biomolecular structure prediction models (e.g., AlphaFold- or Protenix-style co-folding models) at a leading academic or industry lab
- Publications at major ML conferences (NeurIPS, ICML, ICLR) or top science journals, or widely used open-source models
- Experience with deep learning frameworks such as PyTorch or JAX, including multi-GPU training
Preferences- Experience modeling antibody structure and antibody-antigen docking, including CDR loop modeling and epitope prediction
- Experience modeling protein-DNA or protein-RNA complexes
- Deep familiarity with structural data pipelines: mmCIF processing, MSA and template search, structural clustering, and dataset splitting
- Experience with diffusion or flow-matching models for structure generation or structure-conditioned design
- Experience with large-scale distributed training and cloud compute
- Familiarity with experimental structural and binding data (cryo-EM, crystallography, display-based binding assays)
What We Offer - High-growth opportunity with meaningful impact on the future of protein design
- Competitive compensation package with equity participation
- 401(k) with a strong employer match
- Comprehensive benefits including health/dental/vision insurance
- Generous PTO policy and commitment to work-life balance
- Professional development opportunities in a cutting-edge field at the intersection of AI and biology
