Job Description:
The Ground Control Station (GCS) and Command & Control (C2) Software team builds the mission planning, command & control, and post-mission debrief systems that enable operators to seamlessly manage complex, multi-domain unmanned missions. We combine deep desktop application development, modern map-centric interfaces, robust backend integrations, and platform-specific control protocols to deliver a world-class operator experience across air, maritime, space, and effects/expendables. In this role, you will focus on building Ground Control Station software, advanced mission planners, post-mission debrief utilities, and general C2 interfaces. You will work across C++, Qt/QML, QGroundControl (QGC), and full-stack technologies to translate autonomous platform capabilities into intuitive, low-latency, and highly reliable control systems.
In this role, you will design and develop major GCS features, mentor mid-level engineers, and represent the GCS/C2 team directly to autonomy capability teams, flight operations, and external partners. It's a hands-on role for engineers who enjoy designing user-facing controls and mission-critical systems and want to see their code drive complex real-world operations.
