Job description

Collaborate with innovative 3Mers around the world

As a Senior Data Scientist, you will be a key technical leader within the Global Analytics & Insights (A&I) organization, driving the design and delivery of advanced AI/ML solutions that create strategic business value at scale. You will combine deep technical expertise in generative AI, AI agents, and machine learning with strong business proficiency, leading high-impact initiatives and influencing the Innovation direction of the organization.

This role is ideal for experienced data science professionals who are ready to own complex Innovation solution architectures, mentor peers, and bridge the gap between cutting‑edge AI capabilities and real‑world enterprise applications across a global, innovation-driven environment.

The Impact You Will Make in This Role

Advanced AI & Machine Learning Leadership

• Architect, develop, and deploy sophisticated AI/ML solutions across multiple domains, including predictive models, generative AI technologies, agentic solutions, NLP pipelines, and computer vision systems.
• Lead the full Innovation lifecycle - from opportunity identification and discovery through development, deployment, and ongoing performance management.
• Define and own AI/ML model design and development approaches, ensuring technical excellence, scalability, and alignment with 3M standards.
• Drive the adoption and integration of large language models (LLMs), generative AI frameworks, and AI agent architectures to solve complex business problems.
• Establish and enforce model validation, testing criteria, and governance standards across the team.
• Champion responsible for AI/ML principles, including model explainability, fairness, cost management, bias mitigation, and compliance with ethical standards.
• Lead the development and optimization of AI/ML pipelines on/with AWS Bedrock, AWS Agent Core, AWS SageMaker, Azure ML, and Databricks, ensuring production-grade reliability and performance.
• Partner with data engineering teams to define data architecture requirements, pipeline standards, and quality frameworks that support advanced analytics and AI at scale.
• Drive MLOps best practices, including CI/CD for ML, model monitoring, retraining strategies, and deployment automation.

Strategic Influence & Stakeholder Engagement

• Engage proactively with 3M stakeholders, A&I Pillar Leads, and IT COE partners to identify high-value AI opportunities and translate them into structured, impactful solution roadmaps.
• Influence AI technology stack recommendations and contribute to the broader A&I innovation agenda.
• Lead stakeholder engagement throughout solution design, testing, validation, and adoption phases, ensuring solutions are embedded and delivering value.
• Provide technical mentorship and guidance to mid-level Data Scientists and AI Specialists, elevating team capabilities and fostering a culture of technical excellence.
• Communicate complex AI/ML concepts and model outcomes clearly and persuasively to senior technical and non-technical stakeholders.

Documentation & Governance

• Own comprehensive documentation of model architecture, data lineage, performance metrics, and governance artifacts for all AI solutions developed.
• Apply 3M development standards and responsible AI frameworks consistently across all deliverables.
• Proactively identify and mitigate risks related to model bias, data drift, data quality, and solution reliability.
