Safety Test Engineer - Robot Arms

The role

You will plan, develop, and execute test cases for safety functions of robot arms. You will validate safety performance under real conditions and support compliance with relevant standards and documentation.

What you will do

• Plan, develop and execute test cases for safety functions such as emergency stop, protective stop, and safe torque off.
• Validate safety performance including stop times, speed and separation monitoring, and power and force limiting.
• Test safety-relevant interfaces including Safety-I/O and communication between Safety-PLC and controllers.
• Perform fault-injection and negative tests to ensure the system reaches a safe state.
• Support compliance with standards like ISO 10218-1/-2, ISO/TS 15066, ISO 13849, IEC 61508, IEC 62061 and IEC 60204-1.
• Ensure traceability of safety requirements and results from risk assessment to test cases.
• Create and maintain test plans, test reports and verification evidence for the Safety Case and audits.
• Participate in risk assessments, FMEA and hazard analyses from a testing perspective.
• Perform safety-relevant regression tests across software, firmware and hardware variants.
• Develop and maintain automated and semi-automated test environments and test scripts.

Required qualifications

• Bachelor or Master degree in Mechatronics, Robotics, Electrical Engineering, Mechanical Engineering, Computer Science or a comparable field.
• At least 5 years of experience in testing, validation or verification of safety-critical mechatronic or robotic systems.
• Sound understanding of robot arm fundamentals including kinematics, joint and Cartesian movements, coordinate systems and safety limits.
• Good knowledge of functional safety concepts and relevant standards including Performance Level (PL) and Safety Integrity Level (SIL).
• Practical experience with safety-relevant hardware such as Safety-PLC, Safety-I/O, force and pressure measuring devices, oscilloscopes or data loggers.
• Experience in creating structured test specifications, test reports and documentation for requirement traceability.
• Programming or scripting skills in Python and/or Java.
• Experience with CI/CD pipelines such as GitLab and working in agile, interdisciplinary teams.
• Ability to coordinate tasks across teams and provide technical support to less experienced colleagues.
• Very good English skills.

Nice to have

• Experience with test automation such as Cucumber/BDD or Selenium, and Git.
• Experience supporting CE marking procedures or safety certifications by independent testing bodies.
• Knowledge of cybersecurity aspects of safety-relevant systems.
• Experience with ROS or other robotics technologies.
• German language skills.
