Mechanical Engineer, Robotics

SECOND TALENT SG PTE. LTD.; Singapore; On-site; SGD 60,000 - 90,000; Full time

Job summary

SECOND TALENT SG PTE. LTD. is seeking a hands-on mechanical design engineer to own the mechanical systems of our open-source humanoid robot platform. You will design assemblies, drive fabrication, and ensure robust hardware integration.

You’ll create 3D parts and drawings in SolidWorks, run tests, and collaborate with firmware and electronics teams to align mechanical and electrical interfaces. This role emphasizes prototyping and documentation.

Qualifications

• 3+ years hands-on mechanical design experience on high-complexity electromechanical products.
• Strong SolidWorks proficiency across detailed parts, multibody assemblies, surfaces and drawings.
• Experience with sheet metal fabrication and traditional/additive manufacturing.
• Ability to run FEA simulations and interpret results.

Responsibilities

• Design and develop mechanical assemblies across a full humanoid robot body, including joints, actuators, sensor mounts and structural members.
• Build detailed 3D parts, drawings and assembly models across plastics, metal and composites in Solidworks or equivalent CAD tools.
• Run hands-on test rigs — load testing, fatigue cycling, thermal soak and kinematic validation.
• Lead DFM reviews with contract manufacturers, working the shop floor to understand tooling constraints and failure modes.
• Produce and maintain production drawings with GD&T and inspection callouts for manufacturing and QA handoff.
• Set up and instrument test stands, wire sensors and analyze data to close the loop on design iterations.
• Coordinate with firmware and electrical teams on physical integration of actuators, sensors and PCBs, including cable routing and serviceability.
• Contribute build guides, BOM documentation and assembly instructions to the project's open-source hardware releases.

Core Key Skills

• 3+ years of hands-on mechanical design experience on high-complexity electromechanical products
• Strong Solidworks proficiency across detailed parts, multibody assemblies, surfaces and drawings
• Track record with sheet metal fabrication and traditional/additive manufacturing
• Experience with GD&T and producing 2D engineering drawings for manufacturing and QA
• Ability to run and interpret FEA simulations (static, dynamic, thermal)
• Comfortable designing within tight cost and weight constraints without sacrificing reliability
• Hands-on experience with material selection, actuator selection, fasteners and mechanisms
• Proficient in rapid prototyping methods (FDM, SLA, CNC, laser cutting)
• Strong communication skills across suppliers, cross-disciplinary engineers and leadership

Nice to Have

• Experience with bipedal/humanoid robot hardware, legged locomotion, or high-DOF manipulators
• Robotics competition experience
• Python scripting for CAD workflow or data automation
• Familiarity with sim-to-real workflows and control system deployment to hardware
