How to Apply for Reliability Engineer (f/m/x)

at IONITY

🏢 About IONITY

IONITY is at the forefront of transforming long-distance electric vehicle travel by building a high-power charging network across Europe. As a joint venture of major automakers, we are uniquely positioned to shape the future of sustainable mobility. Working here means contributing to a mission that directly combats climate change while solving real engineering challenges.

About This Role

As a Reliability Engineer, you will be the central quality interface ensuring the uptime and safety of IONITY's 350 kW+ charging stations. Your work directly impacts thousands of EV drivers daily, turning potential charging failures into seamless experiences. This role combines hands-on technical analysis with cross-functional collaboration to drive continuous improvement.

💡 A Day in the Life

Start your day by reviewing overnight failure alerts from the network operations team, then dive into data analysis to identify recurring issues. Mid-morning, you might run validation tests on a new firmware version in a lab environment, followed by a video call with a supplier to discuss a root cause analysis. Afternoons often involve documenting findings and coordinating with technical supplier management to prioritize corrective actions.
