## Description

Operating at the intersection of crypto and capital markets, my client builds high-performance trading technology for the rapidly evolving digital asset industry, supporting the entire trading lifecycle. They're looking for detail-oriented engineers with a track record of owning large-scale distributed systems to build the platform infrastructure that underpins their entire trading ecosystem.

This role offers the opportunity to dig deep into high-performance, distributed systems engineering: designing low-latency messaging infrastructure using Aeron, building & evolving API gateways (FIX, WebSocket, REST) and core libraries used by product teams, and maintaining the sequencer and market data distribution pipelines that sit at the heart of their architecture.

If you enjoy getting stuck into the craft of what you build, shaping the infrastructure that every team across the firm builds on, as well as solving problems where the margin for error is low but the space for design is wide open, this role would be perfect for you!
