Low-Latency Software Engineer (Real-Time Crypto Infrastructure). We’re working with a crypto firm building real-time, low-latency systems where microseconds matter. This software sits directly on the transaction path and makes in-flight decisions around fund movement and execution under extreme performance constraints. This is not blockchain protocol work or smart contracts. It’s backend infrastructure that feels closer to high-performance trading or payments systems.
Job Responsibility:
Build and optimise ultra-low-latency, real-time backend systems
Tune for microseconds, jitter, and deterministic performance
Work deep in concurrency, threading, memory, and runtime behaviour
Own critical-path code where performance has real financial impact
Requirements:
Rust, Java, C++ or similar in performance-critical systems
Experience working on low-latency or performance-critical backend systems
Strong understanding of concurrency, multithreading, and lock-free or low-lock design
Proven focus on latency optimisation rather than just throughput
Comfortable working close to the runtime, including memory management and performance tuning
An engineering mindset that obsesses over why something takes 5µs instead of 3µs
