• Test and assess customer returns, identifying faults and confirming effective resolution.
• Perform calibrations on precision equipment in accordance with approved calibration procedures.
• Investigate and correct malfunctions identified during testing.
• Carry out component-level fault‑finding and rework on traditional and surface‑mount printed circuit boards.
• Read and interpret circuit diagrams and schematics to identify relevant components and sections of a circuit.
• Maintain accurate test records, system paperwork and supporting documentation.
• Manage each system as a mini‑project, organising priorities and workload to meet agreed deadlines.
• Provide clear feedback and improvement suggestions to Engineering to support product quality and reliability.
• Develop and improve test methods to increase the efficiency, consistency and effectiveness of the test process.
• Work collaboratively with Engineering, Manufacturing and Customer Support to resolve product and test issues.
• Contribute to a safe working environment and comply with company health and safety requirements.
• Undertake other reasonable duties and responsibilities as required by management.

Core Competencies:
