About The Position

Join a small, high-impact team within Collins Aerospace’s Applied Research & Technology organization in Cedar Rapids, Iowa. We are seeking a Senior Principal Software Engineer to lead the development of resilient, next-generation wireless networking solutions, translating cutting-edge research into real-world capabilities deployed in the field. In this role, you will work at the intersection of innovation and application, helping move breakthrough technologies from concept to mission-ready deployment. At Collins Aerospace, an RTX business, our Applied Research & Technology team operates as a startup-style innovation engine, where small teams are empowered to experiment, prototype, and scale ideas quickly. Within the Defense Technologies segment, you will contribute to resilient communications, secure avionics, advanced sensing, and autonomous systems, with the opportunity to validate your work in real-world environments and see it integrated into platforms that matter. This role does not include direct people management responsibilities but will serve as a subject matter expert, providing technical leadership and guidance across engineering teams.
