We are recruiting on behalf of a dominant High‑Frequency Trading firm currently expanding their automated trading group. They are seeking a Senior Low Latency C++ Engineer to work on next‑generation market‑making and arbitrage strategies.

The Role: You would be joining a high‑P&L, cross‑functional team (Traders, Quants, FPGA Engineers) to build execution logic and order management systems where nanoseconds determine profitability.

Location & Flexibility: This team is operationally distributed across major hubs. We are hiring for a start in London, Austin, New York, Miami, Singapore and Hong Kong depending on your preference and work authorization.

Core Technical Competencies

• Language Standards: Expert-level Modern C++. Must demonstrate mastery of Template Metaprogramming, Move Semantics, Custom Allocators and standard library intrinsics.
• Systems Engineering: Deep understanding of Linux internals, kernel bypass, memory management, SIMD, and hardware/software optimization ("close to the metal").
• Concurrency: Proficiency in multi‑threading, lock‑free architectures, and distributed systems.
• Data structures and algorithms: Open‑addressing, ring buffers, heaps, price‑time priority, spinlocks.

The Challenge

• You will engineer high‑throughput, low‑latency data processing software and order book management systems. You must be capable of optimizing for nanosecond‑level performance to compete against direct market competitors. The feedback loop is immediate. If your code is faster, the trading algorithm wins the trade and makes money instantly.
