  • Developing integrations with external market and execution platforms
  • Building data ingestion and transformation pipelines for high-volume financial data
  • Designing and maintaining RESTful APIs used by internal teams and external partners

  • Experience with monitoring, logging, and observability in production systems
  • Background in financial systems, trading, or market data is a plus but not required
Why This Role?
