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.
  • Application Instructions

    Interested candidates may apply by sending their resume and cover letter to parijat.patel@merai.co with the subject line : “Simulation Expert Application”.
