Collaborate closely with business experts, traders, and quants to deliver complex features
Apply and promote high-quality engineering practices, including automated testing
Proactively identify, troubleshoot, and resolve issues, ensuring long-term stability

We are looking for you, if you have:

Strong foundations in algorithms, data structures, design patterns, and concurrency
Proven ability to build modular, testable, and maintainable systems
Hands-on expertise in Java, Spring Boot, Git, and SQL
Strong analytical thinking and a problem-solving mindset
Good command of English (written and spoken)

You'll get extra points for:

Knowledge of equity derivatives or trading concepts
Experience in financial markets or fintech environments
Familiarity with market data providers and APIs (e.g., LSEG / RFA, Bloomberg B-Pipe)
