Key

Responsibilities: The Firmware / PLC Software Test Engineer will be responsible for the quality verification and validation of PLC-based software used in automated electromechanical systems. This role will serve as an independent software quality function, testing PLC and controls software against defined

requirements, identifying defects and unexpected system behavior, and ensuring software is ready for release. A strong electrical engineering background is highly desirable, particularly for troubleshooting interactions between PLC software, electrical hardware, sensors, actuators, safety devices, and motion-control systems. Serve as a quality-focused PLC software tester, independently verifying PLC software functionality, reliability, and system behavior prior to release.

Develop, maintain, and execute PLC software test procedures, test cases, and verification protocols based on functional and system

requirements. Perform hands-on testing of PLC software on actual equipment, test stations, simulators, and laboratory setups. Verify that implemented PLC functionality meets defined

requirements, expected system behavior, and acceptance criteria. Perform functional, regression, integration, negative, boundary, and fault-condition testing of PLC software. Test system behavior during abnormal conditions, including sensor failures, communication faults, interlock conditions, sequencing errors, and other fault scenarios. Verify proper operation of alarms, events, fault handling, recovery sequences, diagnostics, and system logging.

Identify, document, reproduce, and track software defects through resolution and retesting. Work closely with PLC developers while maintaining an independent testing and quality perspective. Support root-cause investigation of issues involving interactions between PLC software, electrical systems, sensors, actuators, motion-control devices, and other system components.

Develop and improve repeatable test methods and test environments to increase PLC software test coverage and consistency. Maintain clear test documentation, including test results, defect records, traceability, and verification evidence. Support software release readiness by ensuring required testing has been completed and identified defects have been appropriately addressed.

Collaborate with Electrical, Mechanical, Systems, Software, Manufacturing, and Quality Engineering teams during system verification and troubleshooting. Key
