Entry Level Pfizer Global Manufacturing Jobs (NOW HIRING)

We are looking to identify an AI/ML Engineer - Vaccines Modeling and Antigen Discoverywho will play a strategic role at the intersection of artificial intelligence, vaccinology, and translational science.

You will help define the future of AI-driven vaccinology, with the potential to impact human lives globally.

Embedded within Vaccines R&D, supporting viral and bacterial vaccine programs, you will help define how advanced AI methods are applied to unlock new biological insights and accelerate next-generation vaccine innovation.

As an AI Science Engineer, you will work shoulder-to-shoulder with leading Scientists, Immunologists, and Clinicians to translate complex biology into differentiated vaccine strategies.Your work will go beyond proofofconcept models - your AI systems will directly inform scientific hypotheses, experimental design, and portfolio decisions across the vaccine pipeline.

What you'll do:

Model immune response and translational biology

• Conduct the development of predictive and multimodal models of vaccine-induced immune responses, including humoral, cellular, systems immunology, and durability readouts.

• Advance translational modeling approaches that connect preclinical, clinical, epidemiological, and real-world evidence to support dose selection, patient stratification, correlates of protection, and clinical study design.

Accelerate novel antigen discovery and rational vaccine design

• Apply foundation models, generative AI, structure-aware learning, protein language models, and sequence-to-function modeling to identify, optimize, and prioritize novel vaccine antigens.

• Integrate computational antigen design with experimental feedback loops to improve immunogenicity, breadth, manufacturability, developability, and translational relevance.

Build AI-ready data foundations and advance agentic AI and organizational AI fluency

• Partner across scientific, clinical, data, and technology teams to make vaccine R&D data AI-ready through rigorous data standards, metadata, ontologies, quality control, provenance, governance, and reusable data products.

• Design and responsibly deploy agentic AI workflows that support scientific reasoning, literature synthesis, knowledge management, experimental planning, model interpretation, and decision traceability in Vaccine R&D.

• Mentor Scientists, Engineers, and cross-functional partners to raise AI fluency, promote responsible adoption, and represent Pfizer's scientific leadership at the interface of AI, immunology, infectious disease, and vaccine innovation.

What you'll bring

• PhD in Computer Science, Machine Learning, Computational Biology, Software Engineering, AI, or a related discipline OR

• Master's degree in Computer Science, Machine Learning, Computational Biology, Software Engineering, AI, or a related discipline and a minimum of 2 years of applied AI/ML experience in a Vaccines R&D, Life Sciences or other related discovery focused environment

• Working knowledge of vaccine R&D workflows, with emphasis on immune-response modeling, antigen discovery and optimization, and translational science.

• Demonstrated ability to develop and apply quantitative and AI/ML-enabled approaches for translating preclinical immunogenicity, efficacy, and systems-biology readouts into clinically relevant predictions.

• Proven experience working across cross-functional and multidisciplinary teams, including immunology, molecular biology, serology, bioinformatics and data science, to ensure AI models are biologically grounded, experimentally actionable, and clinically meaningful.

• Demonstrated expertise in foundation model, predictive modeling, generative AI, and ML system design.

• Strong programming skills in Python and modern ML frameworks (e.g., PyTorch, TensorFlow), with experience scaling models in cloud and/or HPC environments.

• Experience collaborating with Experimental Scientists, Clinicians, and cross-functional partners.

• Clear scientific communicator with intellectual curiosity and a mission-driven mindset focused on improving patient outcomes
