TL;DR · Protein ML Senior Principal Data Scientist

The Protein ML Senior Principal Data Scientist joins the Vaccines R&D Data and Computational Sciences team to design and deploy machine learning models predicting protein properties. This role focuses on accelerating next-generation vaccine development by predicting immunogenicity, stability, and manufacturability. You will leverage protein language models and foundational AI to identify and optimize vaccine candidates, collaborating with antigen design and bench lab teams to translate computational insights into real-world results. Key responsibilities include maintaining the modeling codebase, mentoring colleagues, and analyzing relationships between protein sequences and functional data. Required technical skills include Python, R, SQL, PyTorch, and structural modeling tools like AlphaFold, OpenFold, and Boltz. You should also possess knowledge of ESM, molecular dynamics, next-generation sequencing, and deep mutational scanning to solve complex protein representation problems.

What you'll do

  • Develop machine learning models to predict protein immunogenicity, stability, and manufacturability for vaccine design.
  • Refine language-based foundational protein representations to accelerate the identification and optimization of vaccine candidates.
  • Analyze relationships between protein sequences, structures, and functional data to uncover generalizable representations.
  • Collaborate with structural biology and bench lab teams to iteratively improve protein modeling strategies and model quality.
  • Maintain the modeling codebase using best coding practices to ensure robust, reproducible, and well-documented results.
  • Mentor and upskill colleagues on the latest advances in protein modeling tools and techniques.
  • Communicate scientific findings clearly to internal and external stakeholders across various levels of technical expertise.

What we're looking for

  • PhD degree in Computational Biology, Data Science, Applied Mathematics, Biophysics, or a closely related field.
  • At least 2 years of experience in an industry or academic setting.
  • Exceptional track record in computational biology, protein language models, biophysics, and AI-based predictive models (preferred).
  • Advanced proficiency in Python, R, and SQL with hands-on experience in PyTorch and tools like AlphaFold, OpenFold, and Boltz (preferred).
  • Deep knowledge of protein representation models such as ESM (preferred).
  • Familiarity with molecular dynamics, next-generation sequencing analysis, and deep mutational scanning (preferred).
  • Familiarity with agentic tools such as Claude Code for automated software engineering (preferred).
  • Fluent English language skills.
