Robot Mechanical and Simulation Engineer

Your mission & challenges

We are looking for the owner of how our robots are represented in software: the single source of truth that connects mechanical design to simulation and control. You will be accountable for the fidelity of our robot description (URDF) and for building the modeling foundation the rest of our robotics stack relies on. Should have excellent understanding of material and mechanics. You shall challenge and give inputs to mechanical design.

This capability is being built from the ground up. You will define it rather than inherit it: you set the standards, build the pipeline, and own model quality end to end.

This is a hands-on but strategic role. You will not necessarily produce the CAD, but you will own everything from CAD through to a validated, simulation-ready model, and you will be the reference point across the mechanical, controls, and software teams.

• Robot description fidelity, end to end: be the single point of accountability for our URDF and xacro models and the conventions behind them

• The modeling foundation, built from scratch: define the CAD-to-URDF pipeline, the naming and coordinate-frame conventions, and the version control practices that do not yet exist here

• Physical consistency between design and model: ensure mass, inertia, and kinematic structure in the URDF reconcile with the source CAD and the real hardware

• The validation strategy: define how models are checked in simulation and against the physical robots, so that errors surface during modeling rather than downstream

• CAD modeling standards: set and enforce them in partnership with the mechanical team, so designs flow cleanly into simulation-ready models

• Automation: build the tooling that makes model generation repeatable and removes manual, error-prone steps

What we can look forward to

Must-have:

• Degree in Mechanical Engineering, Robotics, Mechatronics, or a related field, with the judgment to design a modeling system rather than only execute tasks

• Proven experience authoring and owning URDF from scratch / xacro models for real robots

• Strong foundation in rigid-body kinematics and dynamics, coordinate frames, and mass and inertia properties

• Mechanical design experience in robotics

• Fluent at reading CAD assemblies and extracting physical properties (Creo (desired), SolidWorks, Fusion 360, Onshape, or similar)

• Proficiency in Python and C++ for scripting and automation, with sound software engineering habits: version control, modular and maintainable code, and basic testing

• Comfortable building tooling, standards, and simulation pipelines from scratch in an early-stage environment

Nice-to-have:

• Experience with simulation platforms (Isaac Sim, Gazebo, MuJoCo)

• C++ for performance-critical tooling, and experience integrating modeling into CI

• Experience with humanoid, legged, or other complex multi-limb robots

• Experience with ROS or ROS 2
