Job Description
Computational Scientist
Location: Barcelona
About the job
Sanofi has recently embarked on a vast and ambitious digital transformation program. A cornerstone of this roadmap is the acceleration of its data transformation and of the adoption of artificial intelligence (AI) and machine learning (ML) solutions to accelerate R&D, manufacturing and commercial performance, and bring better drugs and vaccines to patients faster, to improve health and save lives.
In alignment to our digital transformation, we have launched a new major strategic initiative in 2023: the Biologics x AI Transformation. This is positioned to be a unique data-driven team, with expertise in AI platforms, data engineering, ML operations, data science, computational biology, strategy, and beyond. We are working as one to identify, design, and scale state-of-the-art AI capabilities targeted to truly transform how we research biologics.
In this role you will be a dynamic people manager looking to apply cutting-edge computation, machine learning / deep learning approaches to revolutionize our large molecule computational tools by contributing to accelerating and improving the process of design and engineering of novel biologics drug candidates.
Main responsibilities

Some years of industry experience with a track record of applying ML/Deep Learning (DL) approaches to solve molecule-related problems is an advantage
Strong familiarity with protein structure or sequence featurization/embeddings
Strong familiarity with advanced statistics, ML/DL techniques including various network architectures (CNNs, GANs, RNNs, Auto-Encoders, Transformers, PLM etc.), regularization, embeddings, loss-functions, optimization strategies, or reinforcement learning techniques
Proficiency in Python and deep learning libraries such as PyTorch, TensorFlow, Keras, Scikit-learn, Numpy, Matpilotlib
Strong familiarity with data visualization and dimensionality reduction algorithms
Ability to develop, benchmark and apply predictive algorithms to generate hypotheses
Strong knowledge of AWS cloud computing services (Azure & GCP is a plus)
Excellent written and verbal communication, strong tropism for teamwork
Experience designing, developing, optimizing, and / or maintaining ML/DL approaches to solve molecule-related problems
Strong understanding of pharma R&D process is a plus
Technical knowledge of software application development and agile methodologies
Understanding and application of data / digital strategy and governance
A change agent with a combination of business, science & technology, and diplomatic skills
