This position is based out of the Toyota Motor North America Headquarters in Plano, TX.

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.
