Job Description:

Exciting Opportunity: Senior Java Software Engineer – Capital Markets (Hands-On Coding Role) - 12 month contract with renewal potential. Are you a hands-on Java developer with deep knowledge of Capital Markets and Post-Trade systems? Do you thrive in complex, high-performance environments where you're trusted to own your code from development to production? ... We’re looking for a Senior Java Software Engineer to join a dynamic global team working on an enterprise-grade post-trade operations platform built in-house for scale, performance, and resiliency. If you're someone who codes daily, understands SWIFT messaging, and can navigate production support with confidence, this is your opportunity to work on systems that power global financial markets.

Job Responsibility:

  • Lead the development of scalable, fault-tolerant microservices in Java 17+, Spring Boot, and Vert.x
  • Collaborate with a global team across Toronto, London, Hong Kong, Pune, and Guangzhou
  • Deliver small, frequent releases using agile and continuous deployment best practices
  • Work directly with product owners and business partners to define and deliver new features
  • Own your code in production—manage incidents, support operations, and ensure system stability
  • Contribute to performance optimization, message streaming, and automation using tools like Kafka, Solace MQ, and Playwright

Requirements:

  • 10+ years of Java development (Must be actively coding daily)
  • Capital Markets experience, particularly in post-trade processing and SWIFT/ISO20022
  • Strong understanding of incident management and handling production support for critical applications
  • Proficiency in microservice architecture, TDD (Junit/BDD), messaging frameworks, and database strategies
  • Familiarity with UI automation tools (e.g., Playwright)
  • Hands-on experience with messaging systems such as Kafka, Websphere MQ, ActiveMQ, or Solace MQ
  • Comfort with CI/CD pipelines, Git-based source control, and use of AI coding tools like GitHub Copilot
  • Willingness to work flexible hours including occasional weekend or shift support

Nice to have:

  • Front-end development with ReactJS, HTML5, and JavaScript
  • Experience with Calypso or CLS systems
What we offer:
  • Work in a true DevOps culture where you build it, own it, and run it
  • Work on mission-critical systems that support millions of trades globally
  • Join a global tech team that values code ownership and collaborative problem-solving
  • Be part of a transformation toward distributed, cloud-native architecture
  • Operate in small pods (4–8 devs), delivering fast, high-impact releases
  • Contribute to a growing Toronto team with direct business impact
