Job Description — Mechanical Design Engineer

About Motorall

Motorall is developing next-generation autonomous mobility and material-handling systems for warehouses, ports, mining and industrial logistics.

Our product portfolio includes Cyborg autonomous mobile robots for 200-1,000 kg payloads , as well as T-REX heavy-duty autonomous vehicles designed for 20-50 tonne cargo movement across ports, mines and industrial environments. Motorall is building integrated robotic platforms combining mechanical systems, electric powertrains, drive-by-wire, sensors, autonomy, fleet management and industrial vehicle architecture .

We are looking for a highly capable Mechanical Design Engineer who can take ownership of the mechanical architecture of our robots and electric vehicles—from concept and CAD through prototyping, testing and deployment.

Role Overview

This is a hands-on product-development role , not a conventional CAD-design position.

The selected engineer will work on the design and development of:

- Autonomous Mobile Robots (AMRs)
- Heavy-duty autonomous ground vehicles
- Electric/hybrid powertrain systems
- Chassis and structural systems
- Drive systems and wheel-end assemblies
- Battery-pack integration
- Steering, suspension and braking systems
- Robotic mechanisms and payload interfaces
- Modular robot platforms
- Trailer/cargo coupling mechanisms
- Mechanical systems for industrial and port environments

The engineer will work closely with electrical, electronics, controls, autonomy and manufacturing teams to develop complete working robotic vehicles.

Key Responsibilities1. Robot Mechanical Design

- Design complete mechanical architectures for autonomous mobile robots.
- Develop chassis, frame, body, payload decks and structural members.
- Design mounting systems for LiDAR, cameras, radar, batteries,



motors, controllers and other sensors/electronics.
- Design mechanical interfaces for conveyor, flatbed, lift and robotic-arm top modules.
- Design mechanisms for loading, unloading, docking and material handling.
- Design mechanical safety systems, guards, bumpers and protective structures.
- Develop mechanisms for autonomous docking and vehicle positioning.

Motorall's Cyborg platform is designed for 200-1,000 kg payloads and supports modular top modules including conveyors, flatbeds, lifts and robotic-arm integration.

1. Heavy Electric Vehicle Design

- Develop mechanical architecture for large electric autonomous vehicles.
- Develop drivetrain layouts for electric/hybrid vehicles.
- Work on motor, gearbox, differential, axle and wheel-end integration.
- Design mounting systems for traction motors and power electronics.
- Perform mechanical integration of battery packs and high-voltage components.
- Design systems for serviceability, maintenance and component replacement.
- Support development of vehicles intended for continuous 24/7 industrial operation.

- EV Powertrain Development

Responsibilities may include:

- Traction motor integration
- Gearbox/reduction-stage integration
- Differential and axle integration
- Driveshaft and coupling design
- Wheel-end design
- Torque and load calculations
- Gear ratio selection and mechanical validation
- Bearing and shaft selection
- Powertrain mounting




- Structural analysis of drivetrain components
- Thermal-management packaging
- Battery-to-powertrain mechanical integration
- Mechanical protection of high-voltage systems

Experience with BLDC, PMSM, induction or other electric traction motors will be advantageous.

1. CAD & Product Design

The engineer will be expected to independently create and manage production-ready CAD.

Responsibilities include:

- 3D part modelling
- Assembly modelling
- Detailed engineering drawings
- GD&T;
- Tolerance stack-up
- Design for Manufacturing (DFM)
- Design for Assembly (DFA)
- Sheet-metal design
- Welded-frame design
- Machined-component design
- Fabrication drawings
- BOM generation
- Engineering change management

1. Autonomous Robot Integration

The mechanical engineer will work alongside the autonomy and electronics teams to ensure that mechanical architecture supports autonomous operation.

This includes:

- Sensor mounting and protection
- LiDAR/camera/radar mounting
- Sensor field-of-view considerations
- Drive-by-wire mechanical interfaces
- Steering actuator integration
- Brake actuator integration
- Motor/controller packaging
- Battery and electronics enclosure design
- Cable-routing provisions
- Service access
- Emergency-stop and safety-system integration

Experience

2-6 years of relevant professional/project experience.

Freshers should generally not be considered unless they have exceptionally solid hands-on experience through major robotics/EV projects, Formula Student, Baja, autonomous vehicle projects, research projects or demonstrated product development.

- AMR/AGV/UGV
- Electric vehicle
