Location: London (On-site)

£400k+ total comp

We are looking for a talented software engineer to join a high-performing team responsible for architecting and delivering the systems that underpin a leading and disruptive global trading operation.

You’ll work on the full lifecycle of high-throughput, low-latency platforms – including algorithmic trading engines, venue connectivity, and real-time pricing infrastructure. Expect deep technical ownership, constant performance tuning, and direct impact on production trading.

What you’ll work on:

• Design and optimise mission-critical systems where microseconds and gigabits matter

• Build core infrastructure for trading strategies: market data, risk, and execution pipelines

• Translate model logic into real-time code with strict safety, throughput, and latency constraints

• Collaborate with quants, infrastructure, and operations to solve complex engineering problems

We’re looking for:

• Exceptional programming ability in Kotlin, Java, or C++

• Deep understanding of algorithms, data structures, concurrency, and networked systems

• Prior experience working in high-performance or real-time environments

• Confidence working close to hardware and tuning Linux-based systems

• Interest in trading systems, low-latency architecture, or distributed data flows

Why Apply:

• Rare opportunity to join a top-tier team owning end-to-end trading systems

• No red tape – small team, high impact, full autonomy

• Engineering-first culture with zero fluff

• Everything you build runs in production and drives real PnL

Discretion guaranteed – we never share your profile without consent.
