Position Overview

At PNC, our people are our greatest differentiator and competitive advantage in the markets we serve. We are all united in delivering the best experience for our customers. We work together each day to foster an inclusive workplace culture where all of our employees feel respected, valued and have an opportunity to contribute to the company’s success. As a Software Engineer Principal Sr within PNC's C&IB Midland organization, you will be based in Pittsburgh, PA or Dallas, TX or Overland Park, Kansas or Littlerock, AK.

We are seeking a strong Senior Software Engineer Principal t to contribute to the design, development, and evolution of enterprise grade .NET applications. This role is hands on and delivery focused, with responsibility for influencing architecture within a defined domain rather than owning enterprise wide strategy.

The ideal candidate is a strong senior engineer who can operate at an architectural level when needed—designing scalable services, modernizing legacy components, and guiding teams through technical decisions—while remaining actively involved in implementation. You will collaborate closely with architects, product owners, and engineering leadership to ensure solutions are robust, secure, and aligned with business needs.
