Candidates selected for roles will be employed as contract workers through Amazon’s approved 3rd party Direct Source provider for the duration of the specified project and will not be an employee of Amazon.We're looking for a Simulation Modeling Engineer to join our team on a 9-month (minimum) contract building physics-based simulation environments for Amazon Robotics. 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.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.What You'll Do:3D 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 structuresCollision Modeling: Create and optimize collision meshes using tetrahedral meshing workflows (RoLoPoly, TetGen, Drake mesh refiner) for accurate physics contact simulationSensor Setup: Configure simulated cameras, depth sensors, and other perception hardware with accurate field-of-view parametersValidation: 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 deliveriesRequired 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 similarFamiliarity with mesh processing: decimation, convex decomposition, tetrahedral meshing, collision geometry generationUnderstanding of rigid body kinematics (joint types, coordinate frames, forward/inverse kinematics)Proficiency in Python for scripting asset pipelines and automation1+ 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 oversightPreferred skills:Experience with USD (Universal Scene Description) model formatFamiliarity with PBR materials, glTF format, and real-time rendering pipelinesC++ experience (our simulator core is C++)Web 3D visualization (Three.js, WebGL)Understanding of simulation contact models and deformable body simulationExperience converting CAD (SolidWorks, STEP, IGES) to simulation-ready assetsFamiliarity with camera simulation (intrinsics, distortion models, synthetic data generation)This posting is for a contract assignment with Tundra Technical Solutions to provide services to Amazon.The pay range that Tundra in good faith reasonably expects to pay for this position is $69.11/hour - $78.33/hour.Tundra’s benefits offering includes optional medical, dental, vision, retirement benefits, and a New Child Benefit.Pursuant to the California Fair Chance Act, Los Angeles County Fair Chance Ordinance for Employers, Los Angeles Fair Chance Initiative for Hiring Ordinance, and San Francisco Fair Chance Ordinance, qualified applicants will be considered for assignment with arrest and conviction records. Criminal history may have a direct, adverse, and negative relationship with some of the material job duties of this position. These include the duties and responsibilities listed above, as well as the abilities to adhere to company policies, exercise sound judgment, effectively manage stress and work safely and respectfully with others, exhibit trustworthiness, meet client expectations, standards, and accompanying requirements, and safeguard business operations and company reputation.Tundra Technical Solutions is among North America’s leading providers of Staffing and Consulting Services.
