We are seeking a Senior Principal Scientist in AI/ML to lead the development of next-generation antibody therapeutics. This role sits at the intersection of computational biology, machine learning, and antibody engineering; building AI-driven platforms that accelerate therapeutic discovery from concept to clinic.

You will drive the internal build and external partnerships required to create and validate AI/ML platforms, including large language models and in silico protein design tools. Working closely with antibody engineers, structural biologists, and AI/ML scientists, you will shape strategy, guide technical execution, and translate advanced computational methods into impactful biotherapies.

This is a rare opportunity to define how AI/ML is embedded into antibody discovery, influence platform-level decisions, and deliver novel therapeutics from world-class research facilities.

A typical day in the life of a Senior Principal Scientist AI/ML Antibody Design and Engineering may include the following responsibilities:

+ Develop novel AI and machine learning tools to enable de novo antibody discovery with unique properties and in silico co-optimization of affinity, expression, stability and PK/half-life.

+ Apply deep learning and generative AI techniques to train/enhance LLM or other relevant language models using internal datasets.

+ Use in silico protein/antibody engineering design tools such as Rosetta to drive for structure-based design and engineering.

+ Collaborate and support scientists from antibody engineering, therapeutic areas and other tech centers to deliver novel molecular entities to our pipeline.

+ Serve as an expert in computational biologic design to keep up with the latest advancements in AI, machine learning, and protein engineering fields

+ Maintain data records and present to cross-functional teams.

This role may be for you if:

+ You want to build and lead a new AI/ML function from the ground up.

+ You're energized by translating cutting-edge computational methods (LLMs, geometric deep learning, generative models) into therapeutics that reach patients.

+ You have deep expertise in computational biology and protein engineering, and you're ready to apply it at the intersection of AI and antibody discovery.

+ You thrive working across disciplines and partnering with experimentalists, structural biologists, and AI/ML scientists to solve antibody discovery problems.

+ You're ready for a role where your technical decisions shape platform direction and directly accelerate drug timelines.

To be considered for this opportunity, you must have a PhD in Computational Biology, Bioinformatics, Computer Science, Structural Biology or a related field, with 7-10 years of relevant experience. You have proficiency in programming languages such as Python, R and C++. You must have a strong track record of innovation and research accomplishments in developing AI/ML methods and using deep learning tools to successfully solve antibody/protein engineering challenges. Experience in using structural modeling and design tools (e.g. Rosetta) is strongly preferred. Candidates with PhD only in a relevant field will be considered at the Principal level as well.
