About The Position

RTX is hiring a Software Engineer I to develop flight-critical embedded software for next-generation aviation and mission solutions. The role is based primarily onsite in Cedar Rapids, Iowa, and involves hands-on work with embedded Linux, C/C++, networking protocols, device drivers, hardware interfaces, and simulation environments. The engineer will contribute to high-integrity systems that meet rigorous safety, reliability, and airworthiness standards. The position covers the software lifecycle, including defining requirements, implementing features, developing test procedures, performing verification activities, and producing certification-ready artifacts. Work also includes developing embedded HMI and GUI applications using Microsoft .NET Framework and constructing engineering lab stations with hardware test equipment. The role offers exposure to advanced avionics processing and computing technologies, software architecture through certification, safety-critical engineering processes, Ethernet protocols and switching networks, and graphics and video protocols. U.S. citizenship is required because the role involves access to information under a U.S. program or contract. No security clearance is required.

Requirements

Strong development experience with C and C++.
Bachelor’s degree in Computer Science or a related STEM major by the start date; qualifying experience may be obtained through on-the-job experience, research, coursework, or projects.
