Description
Your Impact at LILA
Our Platform Evaluation team tests and benchmarks alternative robotics platforms, including mobile manipulators, AMRs/AGVs, and other form factors, against our current production baseline. The team builds custom mobile manipulators by combining off-the-shelf components from different AMR and robot arm manufacturers, for example mounting one or more arms from a given vendor onto an AMR base from another.
As the Robotics Mechanical Design Engineer, you will own the mechanical design of these custom configurations end to end: mocking up multiple iterations (different arm brands, mounting positions, and configurations), modeling them fully in CAD, and preparing designs for simulation and physical build.
You will work closely with the Platform Evaluation engineers, who validate designs in simulation (NVIDIA Isaac Sim) and in physical testing once built. This is a hands-on mechanical and mechatronic design role, not a robotics software or controls position.
What You'll Be Building
- Design and iterate mounting and integration concepts combining robot arms with AMR/AGV base platforms
- Produce multiple design options per platform combination for evaluation
- Model custom mobile manipulator configurations in CAD, including brackets, structural supports, and interface hardware
- Run mass, center-of-gravity, and payload analysis to keep configurations within manufacturer specifications
- Design cable, hose, and connector routing between the arm, end effector, and AMR base
- Prepare simulation-ready CAD models and specifications (exportable URDF/mesh geometry) for Isaac Sim validation
- Document design decisions, tolerances, and assembly procedures, and support physical build and integration
What You'll Need to Succeed
- Mechanical or mechatronic design experience in a production, commercial, or applied R&D setting, ideally involving robotics or automated equipment
- Strong proficiency in 3D CAD software (SolidWorks, Fusion 360, Onshape, or similar)
- Experience designing mechanical mounts, brackets, or structural interfaces for hardware integration
- Understanding of payload, mass properties, and center-of-gravity considerations for robotic arms on mobile bases
- Familiarity with robot arm and AMR specifications, including mounting interfaces, payload limits, and reach envelopes
- Comfortable iterating quickly, producing and revising multiple design options rather than one final design upfront
- Strong documentation habits, with the ability to communicate design intent and constraints to a non-mechanical audience
Bonus Points For
- Experience preparing CAD models for downstream simulation use, exporting clean geometry at a level of detail suited to URDF/mesh conversion
- Experience with robot arms and AMRs specifically, rather than general industrial equipment
- Familiarity with ROS2/URDF conventions
- Experience with NVIDIA Isaac Sim or other robotics simulation tools
- Background in industrial design for warehouse automation, logistics robotics, or manufacturing equipment
- Experience with rapid prototyping methods such as 3D printing, sheet metal, and machining for early design iterations
Compensation
We offer competitive base compensation with bonus potential and generous early-stage equity. Your final offer will reflect your background, expertise, and expected impact.
U.S. Benefits. Full-time U.S. employees receive a comprehensive benefits program including medical, dental, and vision coverage; employer-paid life and disability insurance; flexible time off with generous company wide holidays; paid parental leave; an educational assistance program; commuter benefits, including bike share memberships for office based employees; and a company subsidized lunch program.

About this role
Lila Sciences' Platform Evaluation team benchmarks different robotics systems by building custom mobile manipulators—combining robot arms from one manufacturer with autonomous mobile bases from another. As Senior Engineer II in Robotics Mechanical Design, you would own the mechanical design of these integrations end to end: conceiving multiple mounting and configuration options, modeling them fully in CAD, and preparing designs for simulation and physical testing. This is hands-on mechanical and mechatronic work, not software or controls—you'll design brackets and structural supports, run mass and payload analyses, route cables and connectors, and document assembly procedures to support the team's validation process in NVIDIA Isaac Sim and physical builds.
The role calls for solid production or applied R&D experience in mechanical design, ideally with robotics or automated equipment. You'll need strong 3D CAD skills (SolidWorks, Fusion 360, Onshape, or equivalent), a working grasp of payload and mass properties for robotic systems, and familiarity with how robot arms and AMRs actually work—their mounting interfaces, payload limits, and reach envelopes. The job rewards people who iterate quickly, produce multiple design options rather than perfecting one, and communicate design constraints clearly to non-mechanical teammates. Experience preparing CAD for simulation, knowledge of ROS2 and URDF conventions, or background in warehouse automation and rapid prototyping methods would strengthen your candidacy.
Based in Cambridge, this is a full-time in-office position with base salary from $136,800 to $190,634, plus bonus and early-stage equity. U.S. employees receive comprehensive medical, dental, and vision coverage; employer-paid life and disability insurance; flexible time off; paid parental leave; educational assistance; and subsidized lunch.
