Simulation Engineer

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

510+ 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.
