The Role
This is a front-office engineering role, not a generic backend position. You’ll be building institutional-grade trading connectivity, sitting directly on the execution pathway between clients and the market. The platform you’ll work on handles:
- Real-time order flow
- Client API integrations
- Low-latency trading connectivity (FIX + modern APIs)
This is revenue-impacting infrastructure, not internal tooling.
What You’ll Be Doing
- Designing and building high-performance Java services powering trading APIs
- Developing and optimising FIX connectivity for institutional clients
- Owning end-to-end delivery — from design through to production
- Improving latency, throughput, and system resilience
- Working closely with product and commercial teams on client-driven requirements
- Building scalable, cloud-native services with strong observability and automation
Tech Environment
- Java (core, concurrency, multithreading)
- Spring / Spring Boot
- FIX Protocol / API connectivity
- Event-driven / distributed systems
- AWS / cloud-native architecture
- Linux production environments
What They’re Looking For
- Strong Java engineering fundamentals in real-time or distributed systems
- Experience building external-facing APIs or connectivity layers
- Understanding of performance optimisation and system design under load
- Exposure to trading systems, fintech, or low-latency environments is highly relevant
- Engineers comfortable operating in high-impact, production-critical systems
Why This Role
- Direct ownership of client-facing trading infrastructure
- Work that sits close to revenue and execution, not buried in internal systems
- A genuine opportunity to build and shape platform capability, not just maintain it
- Environment that values:
- Engineering quality
- Delivery speed
- Pragmatic problem solving
Who This Suits
- Engineers already in trading / FIX environments looking for more ownership
- Strong backend engineers wanting to move into capital markets infrastructure
- Developers who prefer high-impact systems over low-stakes microservices work
Working Model
Hybrid: 3 days onsite, 2 remote
Competitive base + bonus + flexible benefits package
