Amazon Mechanical Engineer II Last Mile Delivery 

United States, California 

854567448

The Last Mile challenge is a fascinating blend of real-world complexity and technological innovation. We're tackling multidimensional problems that involve orchestrating complex delivery networks, optimizing routes through dynamic environments, and adapting to everything from unexpected city events to seasonal weather patterns – all while ensuring every package arrives as per our promise.Key job responsibilities
Lead mechanical design of robotic subsystems and van integration
Design and route cabling and wire harnesses, ensuring reliability, serviceability, and thermal/electrical integrity.
Contribute to thermal management strategies for motors, sensors, and embedded compute hardware.
Integrate sensors such as lidar, stereo cameras, IMUs, tactile sensors, and compute modules into compact, functional assemblies.
Prototype and test mechanical systems; support hands-on builds, debug sessions, and field testing.
Conduct root cause analysis on system-level failures or performance issues and implement design improvements.
Apply Design for Manufacturing (DFM) and Design for Assembly (DFA) principles to transition prototypes into scalable builds (10s–100s of units).

- Bachelor's degree in mechanical engineering or equivalent
- 3+ years of working in mechanical engineering or equivalent experience
- Bachelor’s or Master’s degree in Mechanical Engineering, Mechatronics, or a related discipline
- 3+ years of experience designing mechanical systems for robotics or complex electromechanical products
- Strong proficiency in 3D CAD (e.g., SolidWorks, OnShape, or equivalent)
- Significant hands-on experience building prototypes, integrating hardware, and troubleshooting mechanical/electromechanical issues
- Solid knowledge of DFM/DFA principles and exposure to volume production (50+ units)

- Exposure to designing, testing and validation for compliance (design for safety) and environmental factors (thermal, vibration, ingress protection, etc.)
- Experience with structural analysis practices and tools (e.g. FEA/Ansys), thermal analysis, and material selection.
- Experience with formal engineering documentation and design review processes in a corporate R&D setting.
- Experience with sensor systems and their mechanical integration.
