You will work on highly available, low-latency and financially critical back-end services that handle order flow, market data, risk, balances, assets and exposure management at scale. Your work will directly impact how customers trade, how liquidity is managed, how portfolios are valued, and how Bitpanda operates safely and efficiently across markets. You will collaborate closely with product, quantitative, risk and trading stakeholders to deliver resilient, high-performance systems that form the backbone of our trading platform.

What you'll do

 * Design and develop scalable, resilient, message-driven services using Java
 * Write clean and future proof code with 80% unit test test coverage, end to end and integration testing before deploying into event driven microservices architecture
 * Optimise payment modules/services to ensure reliability, maintainability, performance and scalability
 * Drive innovation by researching and adopting the latest trends and technologies in backend development, ensuring our applications remain cutting-edge
 * Be a technical mentor for junior developers, providing guidance and support to help them grow and excel in their careers
