Simulation Engineer

Job Title: Simulation Expert (Sim/Middleware) Location: Vapi, Gujarat Employment Type: Full-TimeOverview We are seeking an experienced **Simulation Expert (Sim/Middleware)** to own photorealistic and physics-accurate simulation, scenario generation, and CI-at-scale evaluations. This role will involve developing, maintaining, and optimizing simulation stacks for robotics testing, validation, and deployment readiness across multiple domains including humanoids, AGVs, cars, and drones. Key Responsibilities • Deploy and manage simulation stacks such as Isaac Sim, Unity, Unreal Engine, Gazebo, and MuJoCo; support both HIL and SIL. • Design and implement scenario generators, rare-event sampling, and domain randomization techniques. • Develop and calibrate sensor models (camera, LiDAR, radar, IMU, GPS) with precise timing and synchronization. • Build log-replay and closed-loop evaluation harnesses with KPI measurement.Must-Haves • 5–10+ years of experience in simulation for robotics or autonomous systems. • Strong proficiency in C++ and Python programming. • Hands-on experience with robotics middleware (ROS 2) and containerization. • Expertise in large-scale data I/O pipelines and deterministic builds.Nice-to-Haves • Experience with digital twins and fleet-in-the-loop simulations. • Background in generating synthetic data for VLM and Perception systems.Success Metrics • Reduction of sim-to-real performance gaps. • Breadth and depth of scenario coverage. • Simulation throughput (runs/day). • Cost efficiency per run.Domain Notes Humanoids: - Manipulation physics, friction, and contact modeling.AGVs (Autonomous Ground Vehicles): - Warehouse digital twins and traffic rule simulation.Cars: - Adversarial traffic agents; weather and lighting variability sweeps.Drones: - Wind and turbulence modeling; RF/GNSS effect simulation.Application Instructions Interested candidates may apply by sending their resume and cover letter to with the subject line: “Simulation Expert Application”.
