Job description

Prepare test plans, test protocols and procedures for performance characterization, durability, accelerated stress and dynamic cycling tests. Support commissioning of the test system, including verification of sensors, interlocks and safety logic through to final tester acceptance. Manage routine calibration and verification of test instruments to ensure measurement accuracy. Execute testing and data analysis of PEM electrolyser stacks. Adapt quickly to different test types, tester designs and functionalities. Guide test technicians with clear instructions for continuous monitoring of stack and system operation and performance. Process and analyse large multi-channel datasets from operating stacks, including individual cell voltages, stack voltage/current, temperatures, pressures, flow rates, etc. Define, calculate and track key performance indicators such as cell voltage spread, energy consumption, efficiency, degradation rate and gas crossover. Perform cell-to-cell and stack-to-stack statistical analysis and correlate test results with stack build data to identify root causes of variation. Perform gas chromatography (GC) analysis and data evaluation to support performance characterisation and identify anomalies and key trends. Apply electrochemical characterisation methods for performance evaluation and diagnostics of electrochemical systems. Collaborate with cross-functional engineering teams to analyse and correlate stack and system performance. Lead root cause analysis (RCA) of system failure modes and oversee troubleshooting and maintenance of the testers. Record and manage test deviations, non-conformances and corrective actions and provide feedback to stack design and materials teams. Prepare test reports, technical summaries and presentations for internal reviews and project updates. Drive continuous improvement initiatives to enhance testing efficiency, quality and reliability. Ensure compliance with all health, safety and environmental regulations.
