Low-Latency Software Engineer

Low-Latency Software Engineer (Real-Time Crypto Infrastructure)

REMOTE

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.

What you’ll do

• 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

What they’re looking for:

• 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

Apply if you’re interested in crypto infrastructure built with a trad-fi performance mindset, real systems, real constraints, real impact.
