Software Engineer – Mission Management Systems

Overview

In this role you will drive end-to-end development of high-integrity aircraft software during a pivot towards autonomous capabilities. You will own mission system software for both legacy manned platforms and new uncrewed systems, enabling robust reliability while enabling modular open architectures. You will work across dual-platform architectures, open architectures, and regulatory contexts to deliver autonomous capabilities in a cross-functional setting. This is a hands-on, impact-focused opportunity to shape mission management software in a safety-critical domain.
