About the role
This is a core infrastructure role on a small, focused team, based hybrid (4 days in office) out of New York, NY or Lisle, IL. You will be one of the foundational engineers shaping and building our new execution platform — a low-latency, C++-based system with client-facing FIX connectivity, institutional-grade risk controls, and deep integration across U.S. exchanges and dark venues. Found on 1752vc Careers, the job board for startup and VC roles.
What they're looking for
- 7+ years of experience building high-performance, low-latency systems in C++ in a production environment
- Deep knowledge of FIX protocol (4.2/4.4) and the full order lifecycle — entry, routing, execution, cancellation, and reporting
- Experience with exchange market data protocols (ITCH, OUCH, binary feed formats) and building production-grade feed handlers
- Strong understanding of low-latency architecture — kernel bypass, lock-free data structures, CPU affinity, memory layout, and hot-path profiling
- Experience with multicast messaging (Aeron, LBM, or equivalent publish/subscribe transport)
- Solid grasp of U.S. equity market structure: order types, Reg NMS, venue routing, lit and dark pools
