About the job

🚀The opportunity:

Join Sanofi's Biologics AI & Design team at the forefront of a revolution in drug discovery. We're building next-generation foundational models that are directly shaping our therapeutic pipeline — designing antibody and NANOBODY® molecules that will become tomorrow's medicines for patients worldwide.

You'll be part of a elite global team within our Digital Biologics Platform (DBxP), working at the intersection of cutting-edge AI research and real-world therapeutic development. This isn't just about publishing papers or building models in isolation — it's about deploying foundational models that directly impact drug candidates moving through our portfolio.

What makes this role unique:

• 🧬Proprietary biological data at scale — Access to one of the world's largest proprietary datasets of antibody sequences, structures, and functional annotations from decades of therapeutic development

• 💻World-class compute infrastructure — State-of-the-art GPU clusters and cloud resources for training large-scale foundational models

• 🎯Real therapeutic impact — Your models will be validated against real targets and integrated into live drug discovery programs

• 📚Scientific freedom — We encourage publication, conference participation, and collaboration with leading academic labs

• 🌍Global collaboration — Work with interdisciplinary teams across computational biology, protein engineering, and therapeutic development

🎯 What You'll Do

Build the future of protein therapeutics design:

• Architect and train next-generation foundational models for antibody and NANOBODY® design, including protein language models, structure prediction models, diffusion-based generative models, and multimodal architectures

• Push the boundaries of generative protein design — develop novel training strategies, fine-tuning approaches, and inference methods that leverage Sanofi's unique biological data assets

• Bridge research and application — deploy your models into production pipelines where they'll be used to design real therapeutic candidates against challenging targets

• Validate rigorously — design benchmarking strategies and work with wet-lab teams to experimentally validate model predictions on therapeutically relevant targets

• Collaborate across disciplines — partner with antibody engineers, structural biologists, screening teams, and therapeutic area experts to understand biological constraints and opportunities

• Stay at the cutting edge — monitor emerging architectures and methods, evaluate their potential, and rapidly prototype new approaches

• Contribute to the scientific community — publish your work, present at conferences, and help establish Sanofi as a leader in AI-driven biologics design

About you

🧠 What You Bring

Education & Experience:

• Ph.D. in computational life sciences, computer science, machine learning, bioinformatics, or related field (or M.Sc. with exceptional track record)

• Deep expertise in modern deep learning architectures - transformers, diffusion models, flow matching, VAEs, or other generative modeling paradigms

• Hands-on experience training large-scale models - you've trained models with millions to billions of parameters and understand distributed training, optimization strategies, and scaling laws

• Strong foundation in protein science - understanding of protein sequence-structure-function relationships, ideally with focus on antibodies or therapeutic proteins

• Publication track record demonstrating impact in foundational model development, generative modeling, and/or computational protein design

• undefined

Technical Excellence

• Expert-level Python programming and deep learning frameworks

• Experience with ML/DL models for protein design (ESM, ProteinMPNN, RFdiffusion, AlphaFold, etc.) - training, fine-tuning, and application

• Proficiency with distributed training frameworks and cloud/HPC environments

• Software engineering practices - version control, testing, documentation, reproducibility

• Familiarity with biological databases, sequence analysis tools, and structural biology software

Personal Attributes:

• Intellectual curiosity - you're excited by hard scientific problems and driven to solve them

• Collaborative mindset - you thrive in interdisciplinary environments and can communicate complex technical concepts to diverse audiences

• Pragmatic innovation - you balance cutting-edge research with practical application and understand the importance of validation

• Scientific rigor - you design robust experiments, think critically about limitations, and are honest about uncertainty

• Self-motivated - you can work independently, prioritize effectively, and drive projects forward

• Passion for impact - you're motivated by the opportunity to develop medicines that improve patients' lives
