We are seeking an experienced Senior Software Engineer to help build the foundation of our exchange. You’ll ship the core trading infrastructure our market runs on: the matching engine, market data distribution, our customer-facing trading interface, APIs for market participants and clearinghouses, real-time surveillance and monitoring, and the data pipelines behind trade reporting and analytics. You’ll own architectural decisions that balance performance, reliability, and CFTC regulatory requirements, and weave security and compliance into how we build. Beyond the code, you’ll help evolve our engineering principles as the team grows, mentor new hires, and partner closely with Product, Design, Compliance, Infrastructure, and our earliest customers to turn real market needs into production systems.
