Position: Simulation Engineer (Robotics)
Location: Boston MA 02210
Duration: 7 Months
Job Type: Temporary Assignment
Work Type: Onsite
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:
  • 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 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:
  • 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
  • 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)

TekWissen LLC

WE THE TEKWISSEN PEOPLE

TekWissen offers you a broader portfolio of services, industry-leading solutions, and the meaningful innovations that give you greater flexibility and speed to respond to market dynamics, reduced costs and risk to improve enterprise performance, and increased productivity to enable growth.

To keep pace with global market demands, TekWissen keeps its finger on the pulse of change. Our organized approach to guiding a project from its inception to closure. Managing projects is becoming more and more important as we enter the digital era. To cope with the pace that this transition demands, a method is required to manage projects so they can yield quality work, while incorporating efficient use of time and resources.

Project involves identifying which quality standards are relevant to the project and determining how to satisfy them.

It is important to perform quality planning during the Planning Process and should be done alongside the other project planning processes because changes in the quality will likely require changes in the other planning processes, or the desired product quality may require a detailed risk analysis of an identified problem. It is important to remember that quality should be planned, designed, then built in, not added on after the fact.

Capabilities and accomplishments in one TekWissen business enhance the opportunity for success in the others. Put simply, TekWissen's unique combination of attributes promotes success.
