Booking and Messaging Java Developer (COMBJP00001223) - #2085442

Location: London, UK (Hybrid)
Role Type: Permanent
Tech Stack: Java 8+, Concurrency, Apache Kafka / JMS / TIBCO, Spring Boot, Microservices, Low-Latency

We are building and scaling a complex, high-throughput, electronic trading platform distributed across several international hubs. Our development environment is structured around highly autonomous, functional cells that own their own backlogs-supported directly by Product Owners, Business Analysts, and Scrum Masters.

Specifically, our core engineering focus sits at the intersection of trade booking architectures, static data management, and real-time connectivity workflows. This team is responsible for managing the continuous, asynchronous transaction data pipelines that ingest live trade feeds directly from external international exchanges and trading venues.

• Design, implement, and adapt complex distributed trading workflows to meet shifting market and business demands.
• Optimize high-throughput, low-latency asynchronous processing components to handle massive transaction volumes smoothly.
• Work closely with business domain experts, software architects, and DevOps teams within an Agile Scrum framework to continuously roll out platform improvements.

• Core Java Expertise: Strong background in Java 8 or higher, with an elite understanding of multithreading, concurrency models, and non-blocking asynchronous processing.
• Messaging & Streaming Middleware: Heavy production experience with modern event-driven architectures and distributed streaming tools (e.g., Apache Kafka, RabbitMQ, ActiveMQ, or standard JMS APIs).
• Reactive Systems: Practical familiarity with Functional Reactive Programming frameworks (such as RxJava, ReactiveX, or the Java 9 Flow API).
• Backend Mastery: Deep knowledge of the Java Spring ecosystem (IoC, MVC, Boot) and a strong command of SQL relational databases (such as PostgreSQL, Sybase, or MS SQL).
• Infrastructure Foundations: Comfortable operating in Linux/Unix environments and managing builds natively with Maven or Gradle.

• Hands-on experience with specialized low-latency or proprietary enterprise message brokers (e.g., 60East AMPS, Solace, or IBM MQ).
• Exposure to traditional enterprise architectures (such as TIBCO RV) to assist in analyzing and modernizing legacy financial workflows.
• Familiarity with managing cloud-based event brokers (AWS SQS/SNS, Google Pub/Sub, or Azure Event Hubs).
