Senior Robotics Mechanical Design Engineer

Lila Sciences, Inc.; Cambridge (MA); On-site; USD 137,000 - 191,000; Full time

Job summary

Lila Sciences, Inc. in Cambridge, MA is seeking a Senior Engineer II, Robotics Mechanical Design to own end-to-end mechanical design of custom mobile manipulators. You will mock up iterations, model in CAD, and prepare designs for simulation and physical build.

You will work closely with Platform Evaluation engineers, validating designs in simulation and during physical testing. This hands-on mechanical role emphasizes integration and hardware interfaces over software development.

Qualifications

• Mechanical or mechatronic design experience in a production, commercial, or applied R&D setting, ideally involving robotics
• 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

Responsibilities

• Design and iterate mounting and integration concepts combining robot arms with AMR/AGV base platforms
• 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
