Postdoctoral Fellow Generative AI for Antibody Engineering

Rangam is seeking candidates for a Direct Hire role as a Postdoctoral Fellow Generative AI for Antibody Engineering with our client, one of the world’s largest pharmaceutical companies.

Seeking candidates in Cambridge, MA or willing to relocate.

Use Your Power for Purpose

At client's, our purpose is to deliver breakthroughs that transform patients' lives. Central to this mission is our Research and Development team, which strives to convert advanced science and cutting-edge technologies into impactful therapies and vaccines. Whether you are engaged in discovery sciences, ensuring drug safety and efficacy, or supporting clinical trials, your role is crucial. You will leverage innovative design and process development capabilities to expedite the delivery of top-tier medicines to patients globally.

Role Summary

Client's Machine Learning Computational Sciences (MLCS) group is seeking a highly motivated Postdoctoral Scholar to conduct independent and collaborative research in computational antibody design and optimization. This position focuses on the development and application of modern computational and machine-learning–based approaches to accelerate the discovery of next-generation biologic therapeutics. The role sits at the intersection of machine learning, protein science, and therapeutic discovery, ideal for candidates eager to translate foundational AI research into real-world drug design while supporting scientific publication and professional development. The selected postdoc will join a cohort of other AI-focused postdoctoral researchers working on a variety of R&D topics. This community offers opportunities for peer mentorship and exposure to diverse applications of machine learning in discovery and development.

What You Will Achieve

In this role, you will:

• Conduct original research in computational antibody engineering, with an emphasis on sequence- and structure-based generative modeling.
• Develop and deploy state-of-the-art ML methods for multi-objective, constraint-aware antibody optimization balancing affinity, stability and developability.
• Apply proprietary computational framework and ML models for antibody developability engineering.
