Toyota's Digital Innovations group within TMNA's Supply Chain organization is seeking a highly experienced Principal Data Scientist to lead the technical strategy and execution of Supply Chain data science and AI initiatives. This is a technical leadership role that combines deep data science expertise, architectural leadership, and accountability for delivery across complex data, analytics, and software portfolios. As a Principal Data Scientist, you will shape technical approaches, lead complex modeling and product decisions, and guide execution across development teams in alignment with business priorities. While this role is grounded in principal-level technical leadership, it also requires the ability to develop technical talent, influence delivery practices, and step into direct leadership across one or more technical teams when needed. You will partner with engineering leaders, enterprise architects, product teams, and business stakeholders to deliver reliable decision-support solutions, remove execution barriers, and drive measurable business impact, while advancing AI-enabled delivery capabilities that improve productivity, accelerate learning, and strengthen solution quality. This position reports to the Senior Manager, Digital Innovations and plays a critical role in advancing data science standards, accelerating digital transformation, and scaling delivery excellence across Supply Chain products. You will work as part of a fusion team — engineers, product, and Supply Chain operators working to a shared goal and a shared backlog, rather than a technology group taking requests from a business group. This is how Digital Innovations operates. Technical team members are assigned to fusion teams based on priority and need and move between teams and across different parts of the Supply Chain as those priorities shift; in this role you will help set teams up to succeed and keep data science practices consistent as people move. What you'll be doing Define and advance the technical approach for Supply Chain data science and AI products built on AWS, Databricks, and Azure, ensuring alignment with business priorities, enterprise architecture, data governance, and scalable delivery objectives. Lead architecture and design decisions across data science products and development teams, balancing business value, model quality, explainability, resiliency, security, maintainability, and cost optimization. Provide principal-level technical leadership across the full data science lifecycle, from discovery and problem framing through experimentation, model development, deployment, and operational support for analytics, forecasting, optimization, machine learning, and AI workloads. Mentor data scientists, machine learning engineers, technical leads, and engineering managers to elevate technical excellence and strengthen data science capability across the organization. When needed, directly lead technical work across development teams by setting priorities, coordinating execution, and establishing effective delivery rhythms across parallel workstreams. Drive disciplined execution through scaled agile delivery practices — clear user stories, defined acceptance criteria, effective dependency management, risk mitigation, and measurable outcomes across the data science product lifecycle. Work side by side with product, operations, architecture, and platform partners to turn Supply Chain priorities into actionable technical delivery plans for spend and cost analysis, supplier risk, demand forecasting, scenario planning, document intelligence, and AI-enabled decision support. Lead rigorous technical discussions and challenge model, data, and product decisions to ensure solutions meet business objectives, technical feasibility, responsible AI, data governance, and operational excellence standards. Establish and champion modern data science and MLOps practices — reproducible experimentation, model validation, monitoring, deployment automation, observability, reliability engineering, and high-quality software delivery standards. Identify cross-team dependencies and organizational bottlenecks, and drive alignment and decision-making across data science, engineering, product, and stakeholder groups. Provide senior leadership with clear visibility into technical approaches, delivery health, model performance, risks, tradeoffs, and key decisions. Set the standard for AI-assisted data science: use AI as an assistant in your own work, and define where and how teams apply it to improve efficiency, quality, and outcomes — with clear expectations for validation, security, and review. Decide what is worth testing and create the room for the team to test it — running time-boxed experiments and prototypes against models, data, tooling, and emerging technology, and turning what proves out into reusable patterns. Stay close to the operation. Spend time with the buyers, planners, supplier development teams, and other Supply Chain partners who depend on these products so modeling and product decisions reflect how the work actually runs. Champion a culture of accountability, curiosity, experimentation, continuous learning, technical excellence, and inclusive leadership across the data science organization.
