Contribute to digital asset trading systems, including order matching engines, real-time market data feeds, and integration with exchange APIs for trade execution and settlement.
Bring prior experience working with institutional-grade digital asset platforms - such as exchanges, custodians, or tokenization providers - with an understanding of the security, compliance, and operational rigor these environments demand.
