.Net Backend Architect

We are seeking a seasoned Backend Architect with deep expertise in regulated financial systems, trading platforms, and end-to-end trading infrastructure to lead the architecture and backend development of a greenfield Futures Commodity Commissions Market (FCM) platform.

This product will power a federally regulated sports prediction market, akin to Robinhood s financial trading model, requiring full compliance with CFTC and NFA regulations. You will design, architect, and oversee the buildout of a highly scalable, secure, and compliant trading platform operating in a high-performance AWS cloud-native environment.

This role is critical in shaping the front-office (OMS), mid-office (clearing and settlement), and back-office (reporting and compliance) infrastructure from scratch. You'll be expected to act as both a strategic architect and a hands-on engineer.
