What you will do

• Build and calibrate high-fidelity RGB and long-wave infrared camera models in Unreal Engine, including noise, artifacts, motion blur, failure modes, and articulated gimbal views.
• Publish simulated imagery, sensor data, and ground-truth labels to ROS 2 topics for perception and Target State Estimation pipelines.
• Create synthetic-data pipelines for imagery, bounding boxes, segmentation, range, pose, and tracking evaluation.
• Implement configurable dynamic targets and scenario-driven ground-truth rules for proximity, fratricide, and TSE accuracy analysis.
• Manage CAD, 3D assets, materials, and thermal properties for platforms and simulated targets.
• Optimize real-time, accelerated, headless, and CI/CD-based simulation workflows in collaboration with the platform team.

Requirements

• Bachelor’s degree in computer science, computer engineering, robotics, game development, or a related field, or equivalent industry experience.
• 3–6+ years of Unreal Engine and C++ development, including custom plugins or modules.
• Working knowledge of ROS 2 and simulation-environment integration.
• Strong understanding of 3D graphics, real-time rendering, camera projection, FOV, framerate, sensor noise, and camera-based perception.
• Experience with software architecture, design patterns, and collaborative version-control workflows.
• Must be authorized to work in the United States and complete employment eligibility verification through E-Verify.

Nice to have

• Sensor simulation for robotics or autonomous vehicles, especially thermal/IR or multimodal sensing.
• Synthetic-data generation, domain randomization, and sim-to-real workflows for ML perception.
• State estimation, Kalman/EKF filtering, and multi-target tracking.
• Edge deployment with NVIDIA Jetson or TensorRT, UAV flight dynamics, gimbal modeling, or camera-platform geometry.
• GPU programming, procedural environment generation, Python tooling, Blueprint, 3D asset workflows, or distributed simulation.
