Java Low Latency Developer SVP
London | Hybrid (3 days onsite) Top-tier Investment Bank (Global Markets) £160k-£100k base + bonus + benefits
Build the engine behind a $trillions-per-day market
This isn't another Back End Java role.
This is about sitting on the critical path of FX pricing, where microseconds matter, decisions are Real Time, and your code directly impacts global trading performance.
You'll be working inside one of the largest FX franchises in the world, engineering ultra-low latency pricing systems used by traders, quants, and clients across every major currency pair.
What makes this role different- True low latency engineering - not just "event-driven" on paper
- Front Office exposure - direct interaction with traders & quants
- High-impact systems - pricing engines, market data, execution flows
- Modernisation at scale - re-architecting Legacy into high-performance, distributed systems
- Hands-on at SVP level - still coding, still solving hard problems
The work
You'll lead from the front-both technically and strategically:
- Design and build ultra-low latency FX pricing systems
- Optimise performance across JVM, CPU, memory, and network layers
- Work closely with trading desks & quant teams to deliver Real Time solutions
- Drive system re-engineering (Legacy - modern, high-performance architecture)
- Mentor and shape a high-calibre engineering team
- Influence architecture across global FX technology
What they're looking for
- Strong background in low latency/high-performance Java
- Experience in pricing, market data, or execution systems (FX ideal, not essential)
- Deep understanding of:
- GC tuning/low allocation design
- Multithreading/concurrency
- Network protocols/messaging
- System-level performance optimisation
- Proven track record of:
- Building or re-engineering business-critical systems
- Working closely with Front Office stakeholders
- Comfortable operating as a hands-on technical leader
