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.
- Develop modular robot architectures that can be adapted for different payloads and applications.
- 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.
2. Heavy Electric Vehicle Design
- Develop mechanical architecture for large electric autonomous vehicles.
- Design heavy-duty chassis and structural systems for high-payload applications.
- 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.
The T-REX platform is intended for 20–50 tonne cargo handling and uses an electric/hybrid powertrain architecture for port, mining, construction and heavy-industrial applications.
3. EV Powertrain Development
The candidate should be capable of working on the complete mechanical side of an EV powertrain.
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.
4. 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
5. 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 strong hands-on experience through major robotics/EV projects, Formula Student, Baja, autonomous vehicle projects, research projects or demonstrated product development.
The ideal candidate will have previously worked on at least one of:
- AMR/AGV/UGV
- Electric vehicle
- Autonomous vehicle
- Heavy machinery
- Automotive powertrain
- Robotics platform
- Industrial machine
- Mobile robotics
The ideal candidate should:
- Think from first principles.

- Be comfortable with both equations and CAD.
- Be able to take a concept from a blank screen to a physical prototype.
- Understand the difference between a laboratory prototype and a deployable industrial machine.
- Be comfortable working with manufacturing teams.
- Be willing to physically inspect and troubleshoot machines.
- Have strong ownership and execution ability.
- Be capable of independently driving a mechanical subsystem from concept to validation.
Advantageous Additional Skills
Candidates with experience in any of the following will receive preference:
- Formula Student
