Your Mission

As a Senior Engineer at Bitpanda, your mission is to own, design, and scale the highly available, resilient back-end systems powering our core financial ecosystem. Whether building low-latency margin trading infrastructure, real-time risk assessment engines, or seamless payment and compliance pipelines, this work will directly shape how customers interact with digital assets at scale.
