Staff Low-Latency Trading Systems Engineer (HFT)

Design and build exchange-grade trading infrastructure for low-latency market microstructure and crypto-native execution, including Rust order books, matching engines, exchange connectivity, packet processing, risk controls, observability, and market-design architecture.

Responsibilities

• Architect and implement Rust order book and matching engine systems
• Design matching rules, order types, auction behavior, trade reporting, and market-data behavior
• Optimize memory layout, cache locality, allocations, contention, NUMA behavior, and tail latency
• Own exchange connectivity, wire protocols, UDP, TCP, multicast, and user-space networking paths
• Build deterministic replay, kill switches, risk checks, fault isolation, observability, and resilience controls
• Optimize systems across Linux internals, NIC behavior, CPU topology, hardware counters, and accelerator interfaces
• Set technical direction and mentor engineers
• Evaluate and architect CLOB, auction, RFQ, batching, and hybrid market models

Requirements

• Deep expertise in order books, matching engines, exchange connectivity, and electronic market microstructure
• 8+ years building performance-critical low-latency systems in C++, C, or Rust on Linux
• Experience owning hot-path systems at an HFT, exchange, prime broker, or market-infrastructure firm
• Knowledge of network protocols, market-data and order-entry interfaces, user-space packet processing, and Linux networking
• Knowledge of CPU architecture, cache hierarchies, memory models, concurrent design, profiling, and tail-latency optimization
• Ability to architect robust systems with correctness, risk, and operational discipline
• Technical judgment, communication, and staff-level leadership
