# Software Engineer | Ultra-Low Latency Cryptoasset Trading | Faster Than Finality

- **Company:** Mondrian Alpha
- **Location:** Greater London, UK
- **Contract:** Permanent contract
- **Skills:** C++ (Programming Language), Profiling, Data Structures, Distributed Systems, Real-Time Operating Systems, Concurrency, Low Latency
- **Published:** August 26, 2026

## About the Role

* Proven experience building ultra-low latency systems in trading or high-frequency domains
 * Deep understanding of market microstructure and crypto asset behaviour
 * The mindset of someone who thinks in microseconds and measures in CPU cycles
 * Experience optimising global distributed systems operating under strict latency SLAs
 * Comfort driving technical projects from concept to production at scale

## Description

We are partnering with one of the world's most technically ambitious trading firms operating a proprietary crypto trading operation at the physical limits of speed and reliability. This isn't incremental improvement: it's a full-stack architecture of the fastest crypto trading system on the planet, where every nanosecond is contested ground and every cache miss is a bug.

Their engineers operate where nanoseconds decide P&L; measured, profiled, and deployed in live markets where performance is the only edge.

They're now seeking an elite Trading Software Engineer capable of designing and optimising the core of a real-time execution platform; a system that ingests millions of market events per second and executes transactions deterministically faster than anyone else on Earth.

The Successful Engineer Will:

 * Architect zero-copy, lock-free pipelines built around ring buffers and cache-aligned data structures
 * Develop custom market data connectivity for crypto exchanges and protocols, tuned for single-digit microsecond latency
 * Engineer execution algorithms and order management with branch-prediction awareness and SIMD-optimised pricing logic
 * Deliver nanosecond-precision timestamps and cross-system synchronisation across distributed infrastructure
 * Collaborate with quantitative researchers to merge sophisticated trading strategies with execution velocity

The Toolkit

 * Primarily C++ focused, but we're equally interested in engineers with deep Rust backgrounds
 * Profiling and optimisation using perf, VTune, and flamegraphs
 * Deep knowledge of concurrency, lock-free structures, memory ordering, and real-time scheduling
 * Expertise in custom allocator design, CPU cache behaviour, and profile-guided optimisation
 * A habit of benchmarking rigorously: data over assumptions

Ideal Background

 * Proven experience building ultra-low latency systems in trading or high-frequency domains
 * Deep understanding of market microstructure and crypto asset behaviour
 * The mindset of someone who thinks in microseconds and measures in CPU cycles
 * Experience optimising global distributed systems operating under strict latency SLAs
 * Comfort driving technical projects from concept to production at scale
