About the role

ICON is looking for a Robotics Simulation Engineer to join our Software team.
This is a full-time, onsite role is based at ICON's Austin, TX headquarters and will report to the Director of Robotics.
ICON is an equal opportunity employer committed to fostering an innovative, inclusive, diverse and discrimination-free work environment.

Build and maintain high-fidelity simulation environments for ICON's robotic systems.
Develop and tune physics-accurate models of ICON's robotic platforms - including kinematics, dynamics, actuator behavior, and material interaction - validated against physical hardware test data.
Own the sim-to-real gap: systematically measure and reduce discrepancies between simulation predictions and physical system behavior.
Contribute to and maintain shared kinematics and dynamics libraries that are reused across ICON's robotic programs.
Collaborate with controls, perception, and mechatronics engineers to ensure simulated sensor models and environmental conditions are sufficient for algorithm validation.
Participate in design and code reviews to maintain consistency and high-quality output.
As a Robotics Simulation Engineer, you will build and maintain high-fidelity simulation environments that accelerate the development, validation, and certification of ICON's robotic systems.
You will be responsible for developing physics-accurate models of ICON's robotic platforms, bridging simulation and hardware to support a "test-as-you-fly" development paradigm, and contributing to shared kinematics and dynamics toolkits used across all ICON programs.

Master's degree or higher in Robotics, Mechanical Engineering, Aerospace Engineering, or a related field.
3+ years of professional experience in robotic simulation, dynamics modeling, or related robotics software development.
Hands-on experience with NVIDIA Isaac Sim, Isaac Lab, or a comparable physics simulation platform (e.g., Gazebo, MuJoCo, Webots).
Proficiency in modern C++ (17 or newer) and Python within a professional robotics development environment.
Experience integrating simulation environments into automated test and CI/CD workflows.
Familiarity with robotics frameworks such as ROS 2 and their interaction with simulation backends.

Familiarity with physics-informed modeling, including actuator dynamics, joint compliance, and contact/friction modeling.
Experience with sim-to-real transfer techniques and systematic approaches to quantifying and reducing the sim-to-real gap.
Strong analytical and problem-solving mindset; comfortable making data-driven decisions about model fidelity tradeoffs.
