Robotics Simulation Platform Engineer

Robotics Simulation Platform Engineer

About the Role

We are seeking a Robotics Simulation Platform Engineer to build and scale high-fidelity simulation environments, digital twins, and simulation infrastructure for aerial and ground robotic systems. You will focus on simulation platform development, environment building, and system integration - enabling autonomy, perception, and GNC teams to develop and validate algorithms in realistic virtual environments. This role is key to creating scalable, reusable simulation infrastructure and accelerating sim-to-real development across the organization.

Key Responsibilities

• Build, configure, and maintain simulation environments using platforms such as Gazebo/gz-sim, Isaac Sim, Unreal Engine, or Unity
• Develop and integrate vehicle models (geometry, mass/inertia, propulsion, actuation) and sensor pipelines (IMU, GPS, barometer, optical flow, magnetometer, LiDAR, cameras) with physics-accurate noise, latency, and disturbance characteristics
• Design and manage digital twin workflows to replicate real-world system behavior and support sim-to-real validation against real telemetry and flight log data
• Integrate simulation environments with SITL frameworks (PX4/ArduPilot) for closed-loop autonomy and control testing
• Work with physics engines (PhysX, ODE, Chaos, Newton) to ensure stable, deterministic, and highperformance simulation behavior
• Build and maintain simulation tooling, APIs, CI/CD hooks, and reusable components so internal teams can run reproducible SITL test suites independently
• Collaborate closely with GNC and autonomy teams to ensure simulation models and environments accurately support control system validation and flight behavior testing

Required Skills & Experience

• Hands-on experience with robotics simulation platforms (Gazebo/gz-sim, Isaac Sim, Unreal, Unity, or similar)
• Familiarity with robot and vehicle model formats (URDF, SDF) and mesh optimization for simulation performance
• Experience developing vehicle and sensor simulation pipelines including camera/sensor models, noise modeling, timing, and data synchronization
• Familiarity with PX4/ArduPilot SITL, MAVLink, and ROS2-based systems
• Proficiency in C++ and Python for developing simulation plugins and components, with hands-on experience in build systems (CMake/Make) and version control (Git)
• Working understanding of rigid body dynamics, kinematics, and coordinate transformations as applied to multirotor or fixed-wing platforms
• Understanding of physics engine fundamentals collision systems, constraints, numerical stability, deterministic stepping

Preferred Experience

• Experience building digital twins and simulation pipelines calibrated from real-world telemetry or flight log data
• Hands-on experience with SITL/HIL setups and integration with autopilot stacks (ArduPilot, PX4)
• Experience developing custom simulation plugins or components (e.g., Gazebo/Ignition)
• Familiarity with flight dynamics modeling (FDM) for multirotor, fixed-wing, or VTOL platforms
• Experience building or maintaining CI/CD pipelines for automated simulation-based regression testing Contributions to robotics, simulation, or autonomy open-source projects

Education & Experience

Bachelors degree in Robotics, Computer Science, Mechanical, Mechatronics, or related field, with 0-4 years of experience in robotics simulation or related domains.
