The “Fine Print” – What You’ll Do
- Lead and collaborate with an interdisciplinary team of scientists to design and evaluate novel proteins and de novo biological systems in support of therapeutic programs.
- Implement and develop ML-based, protein design solutions for structure prediction, paratope/epitope analysis, affinity maturation, developability assessment, scaffold optimization, library design, immunogenicity and other protein engineering challenges.
- Communicate progress and project recommendations in one-on-ones, project teams and company-wide meetings.
Skills and Experience We Look For
- PhD in computer science, computational biology, structural biology, synthetic biology, biophysics, bioinformatics or related discipline.
- Demonstrated expertise in generative AI and deep learning algorithms, frameworks, associated programming languages and systems architecture.
- The ability to independently design, build and evaluate ML models.
- Expertise in state-of-the-art protein design applications such as Rosetta, AlphaFold2, RoseTTAFold, RFdiffusion, ProteinMPNN, etc.
- Strong working knowledge of protein developability considerations for therapeutic proteins.
- Able to work collaboratively and communicate effectively in interdisciplinary teams.
