Senior Hardware Test Engineer - Actuation

JOB SUMMARY

As a Senior Hardware Test Engineer - Actuation, you will own the validation infrastructure for the robotic actuation systems that power Apptronik’s humanoid robots. This includes defining how actuators are tested, validated, and qualified before they are integrated into the robot and deployed to production.

ESSENTIAL DUTIES AND RESPONSIBILITIES or KEY ACCOUNTABILITIES:

Actuation Test Ownership 

• Serve as the technical owner for manufacturing validation of robot actuators ● Define test strategies for servo-driven electromechanical systems, including: ○ Calibration and alignment
  • Functional validation
  • Performance characterization
  • Fault detection and failure analysis 

• Ensure test coverage supports product reliability and manufacturability Test System Architecture 
• Define the architecture and requirements for actuator test systems and fixtures ● Work with internal software teams to translate test requirements into automated test software 
• Specify instrumentation and interfaces including:
  • Servo drives and motor controllers
  • EtherCAT motion networks
  • Position, torque, current, temperature, and vibration sensors
  • Data acquisition systems 

• Lead integration and validation of automated test stations 

System Integration 

• Collaborate with controls, hardware, firmware, and systems teams to ensure testability is designed into actuator architectures 
• Support integration with manufacturing infrastructure including MES systems and production databases 
• Lead bring-up, debugging, and release of new test stations 

Production Ramp & Sustaining Engineering 

• Support transition from engineering builds to high-volume manufacturing ● Improve test processes for:
  • Yield
  • Cycle time
  • Reliability detection 

• Investigate and resolve production issues related to actuator performance ● Drive continuous improvement of test systems and validation methodologies 

Manufacturing Enablement 

• Develop and maintain:
  • Operator and technician training materials
  • Test equipment maintenance plans
  • Calibration procedures
  • Troubleshooting workflows
  • Create clear, production-ready documentation including test procedures, specifications, and system diagrams
