Job Description:
We are hiring an experienced Senior Software Engineer with deep expertise in ultra-low-latency, high-throughput Java systems. This is a role for someone who builds systems that push performance boundaries, not just enterprise-grade services.
You’ll join a specialist engineering group designing fault-tolerant, sub-40µs latency pipelines, shaping architecture decisions and solving complex technical challenges that require first principles thinking.
What You’ll Be Working On * Designing and optimising high-performance Java services with lock-free, zero-allocation and low-GC approaches.
* Hardware-aware optimisation including CPU architecture, cache behaviour, kernel tuning, core pinning and memory layouts.
* Building and improving ultra-low-latency messaging pipelines (Multicast, TCP, IPC).
* Working directly with senior engineering leadership on system architecture and performance strategy.
* Driving technical direction and mentoring senior members of the team.
What We’re Looking For * 10+ years professional engineering experience with core Java in latency-sensitive environments.
* Strong knowledge of:
* Ring buffers
* Off-heap / zero-allocation techniques
* IPC and high-performance networking
* Linux kernel optimisation
* Domain experience in eTrading, market-making, sports betting, high-frequency messaging or telecoms is highly desirable.
* You thrive in environments where independent problem solving is key.
Why This Role Matters This is not a feature-factory role. You will own problems, drive optimisation decisions, and shape how real-time financial markets infrastructure is engineered.
Location: UK based
Compensation: Competitive base salary + performance bonus + pension + benefits
Working Model: Hybrid flexible
