Mechanical Design Engineer

About the Project: We are looking for an experienced Robotics / Mechanical Design Engineer to help design, develop, and integrate custom end-effectors and gripper systems. Our current robotic arm uses a standard pick-and-place gripper. We want to expand its capabilities by replacing the existing gripper with specialized tools, starting with a screwdriver attachment capable of automatically tightening bolts and screws. Key Responsibilities:

• Design and develop custom robotic grippers and end-effectors.
• Design a screwdriver attachment for robotic bolt and screw tightening applications.
• Evaluate and redesign the mechanical interface between the robotic arm and its end-effector.
• Ensure proper mounting, alignment, stability, and compatibility with the existing robotic arm.
• Account for torque, mechanical forces, vibration, and precision requirements.
• Integrate the new tool with the existing robotic arm while maintaining reliable operation.
• Identify suitable mechanical components, motors, actuators, and mounting solutions.
• Produce detailed 3D CAD models, technical drawings, and engineering documentation.
• Support prototyping, testing, troubleshooting, and further optimization.

Required Experience & Skills:

• Mechanical engineering, robotics engineering, or a related background.
• Experience designing robotic grippers, end-effectors, or mechanical tooling.
• Knowledge of 3D CAD software (SolidWorks, Fusion 360, Inventor, or similar).
• Experience with mechanical assemblies, mounting interfaces, and actuator integration.
• Understanding of torque transmission, mechanical loads, and precision mechanisms.

Nice to Have:

• Experience with automatic screwdriver systems and robotic screwdriving.
• Knowledge of pneumatic and electric actuators.
• Experience with robotic tool changers and modular end-effector systems.
• Familiarity with electrical integration and robotic control systems.

Engagement & Future Opportunities:

• This is initially a freelance / contract-based opportunity, with flexibility depending on the project scope and candidate availability.
• We are, however, open to exploring a longer-term collaboration or potential future opportunities together if there is a good mutual fit.
