FUSE is building the next generation of autonomous defense technology: intelligent robotic systems and multi-domain platforms that redefine how forces operate, sense, decide, and act. Our systems work alongside human operators for surveillance, strike, and mission support At FUSE, we bring together industry pioneers into one agile organization under Elbit Systems, combining the speed, sense of ownership, and innovation culture of a startup with the manufacturing power and operational strength of a global defense leader. Our teams own the full stack end-to-end, from mechanical design, hardware, and embedded systems to robotics, autonomy, AI, and real-time multi-platform decision-making Here, technology goes from concept to operational deployment. Fast. Your work doesn't sit in a backlog. It takes off We are looking for We're looking for a Senior System Engineer to own payload integration for autonomous platforms. You'll architect communication interfaces between EO/IR sensors, laser rangefinders, and flight systems. Your work directly enables precision targeting and real-time intelligence for MUM-T operations In this role you will Define system architecture for payload integration on autonomous platforms Design and validate communication interfaces between EO/IR sensors, LRF lasers, and mission computers Own requirements flow-down from platform level to payload subsystems Lead technical reviews and interface control document development Troubleshoot system-level issues across hardware, firmware, and software boundaries Collaborate with hardware, software, and flight test teams to validate end-to-end performance Support flight tests and analyze system performance data Drive trade studies for payload capabilities and mission configurations Requirements B.Sc. in Electrical Engineering, Computer Engineering, or related field 5+ years in system engineering for defense or aerospace systems Hands-on experience with electro-optical and infrared sensors Strong understanding o
