• Automate testing procedures through scripting to streamline data acquisition, control sequences, and data analysis workflows.
• Implement mission-specific test scenarios, including thermal, vacuum, vibration, and cycling profiles, based on mission requirements-no space background necessary.
• Lead qualification campaigns, ensuring hardware withstands environmental stresses such as thermal extremes, vacuum conditions, and mechanical vibrations.
• Manage and enhance the in-house cell testing laboratory, including thermal chambers, safety systems, and collaboration with suppliers.
• Analyse test data to identify failure modes and guide iterative hardware improvements.
• Ensure compliance with safety standards and best practice measurement techniques in high-voltage and high-current environments.
• An engineering degree (MSc or equivalent) in Electrical Engineering, Electronics, or a related discipline.
• Minimum of 5 years' practical experience in test engineering within the electronics or power systems sector.
• Proven expertise testing batteries or power electronics, including experience with cyclers, thermal chambers, and electronic loads.
• Strong scripting skills in Python or comparable languages for test automation and data processing.
• Deep understanding of measurement techniques, high-current and high-voltage safety practices, sensing, wiring, and grounding.
• Autonomous operation of lab tools such as oscilloscopes, power analyzers, and electronic loads.
• Analytical mindset with a proactive approach, excellent communication skills, and a curiosity-driven attitude.
• Professional proficiency in English; additional languages are a plus.
• Experience working within aerospace, satellite, or other high-reliability industries.
• Knowledge of lithium-ion cell chemistry, including aging, safety test protocols, and health monitoring techniques (ACIR/DCIR, EIS).
• Familiarity with environmental testing standards and procedures.
• Experience testing power electronics assemblies.
• Competency with laboratory data management, databases, and data pipeline tools.
• Experience with test frameworks such as LabVIEW or TestStand.
