• Experience with event-driven design(e.g. asynchronous processing, messaging, domain events)
• Practical experience withcloud platforms(preferablyAWS, or similar)
• Solid understanding ofdatabases, bothNoSQL(e.g. DynamoDB) and/or relational systems
• Comfortable working incomplex, data-heavy domains(ideally Finance), where investigation, analysis, and precision are key
• Communicate clearly in English, open-minded, curious, and motivated to continuously improve both yourself and the systems you work on

We recognize that everyone carries a unique set of valuable skills and experiences. If you think you could have an impact even though you don't meet 100% of the requirements, we still encourage you to apply. We want to hear from you!
