You'll play a key role in designing, building and evolving core services, working closely with other senior engineers and quants.

Responsibilities:

Hands-On Engineering: Designing, developing and maintaining high-performance Java services that are scalable, secure and resilient.
Modern Backend Design: Applying Domain-Driven Design and message-/event-driven design principles to build loosely coupled, well-structured systems.

System Evolution: Helping modernise and evolve existing platforms, balancing pragmatic delivery with long-term architectural health.
Collaboration: Working closely with trading, quants and fellow engineers to turn complex business requirements into robust technical solutions.
Developer Experience: Contributing to improvements in build tooling, CI/CD pipelines, testing approaches and overall engineering productivity.
Operational Excellence: Supporting systems in production, improving observability, performance and resilience.

Experience:

Strong Java Expertise: Proven experience building backend systems using Java and frameworks such as Spring with deep understanding of the JVM ecosystem.
AI Driven Development Focus: experience using AI tooling to accelerate design exploration, prototyping and embedding AI capabilities into product workflows and services
Event Driven Design: Experience designing systems using event-driven approaches (e.g. Solace, Kafka, Web Sockets or similar technologies), with a solid grounding in Domain-Driven Design.
Engineering Fundamentals: Strong grasp of SOLID principles, design patterns, dependency injection and persistence technologies
Problem-Solving Mindset: Solid knowledge of algorithms and data structures, with the ability to reason about performance, complexity and scalability
Cloud-Ready Development: Experience building software for cloud environments, including containerization and modern deployment practices.
Quality & Resilience: Understanding of secure coding practices, fault tolerance and building reliable systems in distributed environment
