Test Engineer

The Opportunity Our R&D team develops innovative technologies that transform how the world operates and how industries do business. We constantly push the boundaries of what’s possible while keeping our focus on delivering high-quality products and solutions to our customers. The Product Innovation & Development team is based in Seville. As part of this group, you will join a multidisciplinary team of highly qualified engineers in power electronics, control systems, firmware, software, hardware, test & validation, and mechanical systems. You will contribute to the development of innovative modular converter platforms for grid-connected and DC applications. This role offers the opportunity to challenge technological limits in efficiency, size, and operational performance. If you’re ready for the challenge, we’d love to hear from you. How You’ll Make An Impact Define and execute test plans for power electronics systems and components. Design, implement, and optimise test benches for the validation of converters and subsystems. Perform functional, performance, and stress tests in both lab and field environments. Collect, analyse, and interpret measurement data, generating clear and reusable technical reports. Ensuring testing activities comply with applicable standards and safety regulations. Support hardware, firmware, and software teams in debugging and resolving detected issues. Contribute to the automation of test procedures and efficiency improvements. Participate in the prototype implementation and validation phases. Prepare documentation, reports, and manuals related to test activities. Your Background Bachelor’s or Master’s degree in Engineering (Electronics, Electrical, Industrial, or related field). Experience in testing and validation of electronic systems, preferably in power electronics or energy systems. Knowledge of laboratory instrumentation (oscilloscopes, power analysers, multimeters, etc.). Familiarity with test automation tools and scripting languages (Python valued). Ability to work in multidisciplinary teams and collaborate effectively. High-level proficiency in English (written and spoken). Valuable Experience Test management and certification processes. Hands-on commissioning of converters and energy storage systems. Hardware-in-the-loop (HIL) testing and simulation tools. Previous experience in renewable energy or power electronics industries. At least 3–5 years of relevant experience will be considered a strong asset.
