Senior Java Engineer - Trading Systems

Senior Software Engineer – Trading Systems

We’re working with a well-established systematic trading firm building and scaling a core platform responsible for processing millions of trades daily and maintaining real-time positions across multiple asset classes.

This is a backend engineering role focused on high-throughput, low-latency systems. The work is heavily Java-based, with a strong emphasis on concurrency and deterministic performance.

You’ll work closely with traders, quants, and engineers on systems that sit directly in the critical path of trading and risk - where correctness and performance genuinely matter.

• Designing and owning Java services for trade capture and position management
• Building and optimising distributed systems handling high volumes of real‑time data
• Working with traders and quants to improve APIs and trading workflows
• Tuning performance through concurrency, caching, and system design

• Engineers with strong Java experience in low‑latency or high‑throughput environments
• People comfortable with concurrency, threading, and performance tuning
• Developers from trading, fintech, or similarly complex backend systems in tech
• Engineers who enjoy owning systems end‑to‑end and working close to users

• Work on systems directly tied to trading and real‑time risk
• Strong engineering culture focused on performance and clean design
• High ownership and close collaboration with technical stakeholders
• A well-resourced environment solving genuinely hard problems
