Exciting Opportunity: Senior Java Software Engineer - 12 month contract engagement with renewal potential
Are you a seasoned Java engineer ready to design scalable, mission-critical systems in a global trading environment? Join a cutting-edge team at the heart of Corporate and Institutional Banking, developing high-performance post-trade platforms that process millions of transactions across global markets. This is not your average coding gig — you’ll design and deliver complex microservices, tackle real-time messaging, and help shape the future of post-trade operations.
Advantages
Be part of a pod-based team where your voice matters — no order takers here
Work in a true DevOps culture where you build it, own it, and run it
Ship code frequently with confidence
Collaborate with top talent across the globe in a fast-paced, forward-thinking environment
Get your hands on modern tech stacks and influence platform evolution
Make a direct impact on how the organization operates its core trading systems
Responsibilities
As a Senior Java Software Engineer, you’ll be a key player in a growing Toronto-based team building an in-house platform transforming how Global Markets Operations delivers and evolves technology.
You will:
Design, build, and optimize Java-based microservices (Java 17+ / 21, Spring Boot, Vert.x)
Drive automation, testing, and frequent production deployments
Work with global teams across Hong Kong, London, Guangzhou, and Pune
Own your code in production — from development to deployment and support
Interface with upstream/downstream systems using Kafka, MQ, REST, and Web Services
Help build and maintain UI components using ReactJS (if you have the skills — nice-to-have!)
Qualifications
10+ years of Java development experience with a deep understanding of back-end architecture
Hands-on expertise in:
Spring Boot, Vert.x, microservices, and Java 17+
Messaging/streaming services: Kafka, WebSphere MQ, Solace, etc.
Test-driven development (TDD) and UI test automation tools like Playwright
Production support and Incident Management processes
Strong understanding of:
Scalability, fault tolerance, security, logging, tracing, and exception handling
Continuous Integration/Deployment and Git-based source control
Familiarity with payments processing (SWIFT, ISO20022) and post-trade systems
Flexibility to provide weekend or shift support if needed
Bonus points for:
Experience with Calypso, CLS, and front-end tech like HTML5, ReactJS
Experience using AI tools like GitHub Copilot for code optimization
Summary
Apply now and help build the next generation of post-trade technology !!!!!
