Robot Modeling Engineer

Location: Zurich, Switzerland

Company

hirify.global develops robotic systems and the software foundations required to model, simulate, and control them.

What you will do

• Own the fidelity of URDF and xacro robot descriptions as the single source of truth across mechanical, controls, and software teams.
• Define the CAD-to-URDF pipeline, naming conventions, coordinate-frame standards, and version-control practices.
• Reconcile mass, inertia, kinematic structures, CAD assemblies, and real hardware.
• Design validation methods for simulation and physical robots so modeling errors are identified early.
• Establish CAD modeling standards with the mechanical engineering team.
• Build automation and tooling for repeatable model generation and simulation pipelines.

Requirements

• Degree in Mechanical Engineering, Robotics, Mechatronics, or a related field.
• Proven experience authoring and owning URDF and xacro models for real robots from scratch.
• Strong understanding of rigid-body kinematics and dynamics, coordinate frames, mass, and inertia properties.
• Mechanical design experience in robotics and the ability to read CAD assemblies and extract physical properties.
• Proficiency in Python and C++ with experience in version control, modular maintainable code, and basic testing.
• Experience building tooling, standards, and simulation pipelines from scratch in an early-stage environment.

Nice to have

• Experience with Isaac Sim, Gazebo, or MuJoCo.
• C++ experience for performance-critical tooling and modeling integration into CI.
• Experience with humanoid, legged, or other complex multi-limb robots.
• Experience with ROS or ROS 2.
• Experience with Creo, SolidWorks, Fusion 360, Onshape, or similar CAD tools.

Culture & Benefits

• Hands-on and strategic ownership of a capability being built from the ground up.
• Direct collaboration across mechanical, controls, and software engineering.
• End-to-end responsibility for model quality, standards, tooling, and validation.
