Vapi, India Meril Full time

Job Title: Simulation Expert (Sim/Middleware)

Location: Vapi, Gujarat

Employment Type: Full-Time


Overview

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.
