booking and messaging java developer (combjp00001223).

About the Team & Platform

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.

What You Will Do

• 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.

What We Are Looking For

• 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.

Nice-to-Have Skills

• 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).
