As a Principal Software Engineer, you build the products we sell to customers. You are a problem solver able to turn a requirement or a design into an operational high-quality product. At Principal level you impact multiple products and contribute to product line design. You insist on the highest standards for design and quality because a working product is ultimately your responsibility. You mentor other software engineers. You welcome input and feedback from peers and other roles in the organization and accept change as inevitable. You deal with ambiguity and come up with a design with minimal input.
