Machine Learning Scientist, Biomolecular Structure Prediction

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 Profluent's 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

Employment Eligibility Verification
