(GA-ASI), an affiliate of General Atomics, is a world leader in proven, reliable remotely piloted aircraft and tactical reconnaissance radars, as well as advanced high-resolution surveillance systems.\nJoin our Perception group to design and implement a real-time Dynamic Environment Model (DEM) to support multi-sensor fusion, track management, and sensor resource management across advanced unmanned systems. This role will design and implement the perception and fusion infrastructure that aggregates radar, EO/IR, ESM, and other sensor inputs into a coherent, uncertainty-aware spatiotemporal world model, enabling high-confidence situational awareness and autonomous decision-making. This role focuses on real-time systems, probabilistic fusion, tracking, data structures, and performance-critical C++.\nDUTIES AND RESPONSIBILITIES:\nBuild and optimize real-time DEM data structures:Spatiotemporal voxel grids / occupancy & belief fields\nConfidence, decay, and provenance tracking\n\nImplement deterministic fusion + perception infrastructure:Sensor synchronization, buffering, time alignment, calibration\nReal-time data association and multi-sensor integration\n\nSupport tracking engineers implementing IMM-EKF/UKF, JPDA, and data association models\nDesign and maintain low-latency transport (ZMQ/DDS/ROS2, shared memory, lock-free queues)\nDevelop tools for:Replay and Monte-Carlo evaluation\nField test debug & metrics\nLive introspection and visualization of DEM states & tracks\n\nCollaborationWork closely with:Tracking & state estimation engineers\nML engineers building feature and occupancy networks\nAutonomy stack and mission systems teams\n\nContribute to sim-to-real validation\n\nWe recognize and appreciate the value and contributions of individuals with diverse backgrounds and experiences and welcome all qualified individuals to apply.","description_format":"text","description_chars":1884,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Energy
