Overview:
TekWissen is a global workforce management provider headquartered in Ann Arbor, Michigan that offers strategic talent solutions to our clients world-wide. Our client is a global technology leader that is transforming the way people shop, consume content, and interact with digital services. With a strong presence across e-commerce, cloud computing, digital streaming, and artificial intelligence, the company is known for its customer-centric approach, innovation-driven culture, and large-scale global impact. It continues to invest in building products and services that improve everyday life while supporting businesses, communities, and economies worldwide.
Job Description:
You'll create, import, and maintain high-fidelity 3D models of robotic workcells, converting CAD designs into simulation-ready assets that enable robot motion planning, controls development, and system validation before physical hardware exists. Purpose of the Team and key projects: Import a new robot prototype station from SolidWorks CAD into the simulator with accurate arm kinematics, rail geometry, sensor placement, and tote collision models Tune simulation assets to balance detail vs execution speed of simulation Convert OBJ collision meshes to VTK tetrahedral format to improve physics contact accuracy for robotic manipulation Build a model validation script that checks inertia values, texture transparency, and mesh integrity at build time
Task Breakdown and Workflow:
3
D Asset Pipeline:
Convert SolidWorks/CAD assemblies into simulation-ready formats (SDF, URDF, glTF, VTK) with accurate kinematics, collision geometry, inertia properties, and visual materials (PBR)
Station Configuration:
Build and maintain robotic workcell configurations including robot arms, rails, sensors, end-effectors, pods, conveyors, and environmental structures
Collision Modeling:
Create and optimize collision meshes using tetrahedral meshing workflows (RoLoPoly, TetGen, Drake mesh refiner) for accurate physics contact simulation
Sensor Setup :
Configure simulated cameras, depth sensors, and other perception hardware with accurate field-of-view parameters
Validation :
Build model integrity tests, verify FK/IK accuracy against real hardware, and maintain asset quality standards (mass, inertia, texture transparency, mesh integrity)
Customer Delivery:
Independently manage asset import/update requests from robotics program teams, meeting SLA timelines for new station deliveries What makes this role interesting: This role sits at the intersection of 3D content creation and robotics engineering. You'll work directly with mechanical engineers, controls teams, and simulation developers to translate hardware designs into accurate digital twins. You'll operate with the autonomy and ownership expected of an L5 individual contributor. Independently driving asset delivery end-to-end, making technical trade-offs, and influencing modeling standards across the team.
Leadership Principles:
Ownership Dive deep
Required Skills:
5+ years professional SW development experience. 1+ year working with 3D modeling tools (Blender, SolidWorks, Maya, or equivalent) Experience with robotics simulation formats: URDF, SDF, MJCF, or similar Familiarity with mesh processing: decimation, convex decomposition, tetrahedral meshing, collision geometry generation Understanding of rigid body kinematics (joint types, coordinate frames, forward/inverse kinematics) Proficiency in Python for scripting asset pipelines and automation 1+ year cumulative experience with at least one of: game engines (Unreal, Unity), physics engines (Drake, MuJoCo, Bullet, PhysX), or robotics simulation platforms (Gazebo, Isaac Sim) Demonstrated ability to independently own and deliver technical work with minimal oversight Nice to haves: Experience with USD (Universal Scene Description) model format Familiarity with PBR materials, glTF format, and real-time rendering pipelines C++ experience (our simulator core is C++) Web 3D visualization (Three.js, WebGL) Understanding of simulation contact models and deformable body simulation Experience converting CAD (SolidWorks, STEP, IGES) to simulation-ready assets Familiarity with camera simulation (intrinsics, distortion models, synthetic data generation)
Must Have Hard Skills:
