Cambridge, Massachusetts, United States
Onsite
ROLE SUMMARY:
Drives practical application of large language models (LLMs) and agentic artificial intelligence across Inflammation & Immunology (I&I) by identifying high-value scientific use cases, building reusable workflows, and partnering closely with scientists to ensure adoption, rigor, and impact. This role sits within AI Delivery & Enablement (AIDE), the Systems Immunology line created to make AI and omics workflows practical across I&I by converting repeat asks into reusable capabilities and helping those capabilities become embedded in day-to-day scientific work.
The Applied AI Workflow Scientist combines entrepreneurial use-case discovery with hands-on implementation of reusable AI workflows and agentic systems. The role is intended for someone who is excited by emerging LLM capabilities but equally committed to applying them responsibly, with scientific credibility, strong user partnership, and a focus on workflows that scale beyond one-off prototypes.
ROLE RESPONSIBILITIES:
Identify high-value, repeat scientific and analytical use cases where LLMs, agentic AI, and workflow automation can materially improve the speed, quality, consistency, or accessibility of work across I&I.
Design, build, and refine reusable AI workflows, prompt/program structures, orchestration patterns, and agent-based tools that support end-to-end scientific narratives rather than isolated task completion.
Partner closely with scientists, clinicians, computational biologists, and other stakeholders to understand real workflow pain points, define fit-for-purpose solutions, and iterate rapidly toward tools that are scientifically useful and operationally adopted.
Translate emerging LLM and agent capabilities into practical scientific applications, balancing speed of experimentation with methodological rigor, grounded usage, human-in-the-loop design, and reusable implementation patterns.
Contribute to technical standards for evaluation, documentation, guardrails, and workflow quality so that AIDE solutions are trusted, reproducible, and suitable for repeated use across teams and projects.
Work across the Digital ecosystem to avoid duplication, leverage existing platforms where appropriate, and ensure that AIDE solutions fit within the broader Pfizer AI and data environment.
Raise AI fluency among collaborators by demonstrating practical workflows, explaining trade-offs clearly, and helping scientists build confidence in responsible use of LLM-enabled tools.
BASIC QUALIFICATIONS:
Bachelors degree and 6+ years of relevant work experience OR Master’s degree and 5+ years of experience OR PhD and 1+ years of experience. Advanced degree in computer science, machine learning, artificial intelligence, computational biology, bioinformatics, statistics, engineering, or a related quantitative or scientific field preferred.
Strong hands-on experience applying LLMs, generative AI, machine learning, or related AI approaches to real-world workflows, products, or analytical use cases.
Demonstrated ability to build practical, reusable workflows or systems rather than one-off analyses, with strong implementation skills in Python and modern AI / ML tooling.
Experience working directly with domain users or stakeholders to translate ambiguous needs into useful technical solutions, with evidence of strong collaboration and communication skills.
Sound judgment regarding methodological rigor, model limitations, evaluation, and the appropriate role of human oversight in AI-enabled workflows.
PREFERRED QUALIFICATIONS:
Experience in life sciences, pharma, biotech, systems biology, immunology, translational science, omics, or related research environments.
Familiarity with scientific evidence synthesis, literature and document workflows, retrieval-augmented approaches, or multi-step knowledge workflows involving unstructured and structured scientific information.
Experience with agentic orchestration, prompt/program design, workflow automation, or multimodal extensions of AI systems.
Comfort operating across scientific and technical disciplines, with enough domain fluency to engage credibly with scientists while still bringing a strong applied-AI builder mindset.

Sunshine Act
Pfizer reports payments and other transfers of value to health care providers as required by federal and state transparency laws and implementing regulations. These laws and regulations require Pfizer to provide government agencies with information such as a health care provider’s name, address and the type of payments or other value received, generally for public disclosure. Subject to further legal review and statutory or regulatory clarification, which Pfizer intends to pursue, reimbursement of recruiting expenses for licensed physicians may constitute a reportable transfer of value under the federal transparency law commonly known as the Sunshine Act. Therefore, if you are a licensed physician who incurs recruiting expenses as a result of interviewing with Pfizer that we pay or reimburse, your name, address and the amount of payments made currently will be reported to the government. If you have questions regarding this matter, please do not hesitate to contact your Talent Acquisition representative.
