Launch improvements and fixes frequently in a fast-paced, regulated environment where reliability matters. * Work across the full stack.

Partner closely with operations, compliance, and product to understand workflows, gather feedback, and iterate quickly on tooling. * Design for scale and compliance. Build systems that handle thousands of daily transactions while maintaining audit trails and meeting CFTC regulatory requirements. * Contribute to technical decisions.
