Principal Software Engineer

The Principal Software Engineer is the senior technical leader and supply chain domain expert on the US Supply Chain Fusion Team, acting as a critical technical bridge between supply chain business operations and core IT solutions. This role powers the IT solutions behind demand planning, procurement, inventory management, warehousing, distribution, and manufacturing logistics.

The Principal Software Engineer spends roughly half of their time on technical strategy, architecture, governance, and Agile leadership, and half on highly complex technical execution across production support and projects.

The position works within an Agile Fusion Team alongside the Digital Product Manager, Digital Product Owner, and IT Global Delivery Leader.
