Senior Calypso Developer
Senior Calypso Developer – Capital Markets Technology
Join a high-performing markets technology environment where you’ll work on business-critical trading and risk platforms supporting complex capital markets operations.
This is a rare opportunity for an experienced Senior Calypso Developer to join a technically mature engineering team delivering large-scale platform transformation and integration initiatives within a sophisticated enterprise environment. You’ll gain exposure to front-to-back trade lifecycle systems, enterprise-scale architecture, and modern delivery practices while working alongside highly skilled technology and business teams.
If you’re looking for a role that combines deep technical engineering, strong project visibility, and long-term career growth in financial technology, this is an opportunity worth exploring.

* Exposure to complex capital markets systems and enterprise-scale architecture
* Strong hybrid flexibility with Sydney CBD offices
* Collaborative agile environment with experienced engineering teams
* Opportunity to influence solution design and platform capability
* Long-term stability with ongoing strategic technology investment
* Excellent environment for someone wanting to deepen financial markets expertise
The Role
As a Senior Calypso Developer, you’ll play a key role in designing, developing, and supporting complex trading and post-trade solutions across front office, risk, and back-office domains.

The role sits within a cross-functional agile team and offers significant exposure to both business and technology stakeholders.

* Work with API, XML, REST, JMS, and messaging-based integrations
* Perform impact analysis, root cause analysis, and production support activities
* Optimise platform performance and support ongoing system enhancements
* Contribute to Calypso upgrades, migrations, and strategic platform initiatives
* Collaborate closely with architects, BAs, developers, and business stakeholders
* Support Agile delivery practices and continuous improvement initiatives
Essential Skills & Experience
- Strong hands-on experience with the Calypso Trading & Risk Management Platform
* Expert-level Java development experience with Calypso APIs and frameworks
* Deep understanding of Calypso workflows, post-trade processing, and schedulers
* Strong SQL, Unix/Linux, and shell scripting capability
* Experience across asset classes including FX, Rates, Fixed Income, Derivatives, and Repos

Nice to Have
- Exposure to Calypso CATT, upgrades, and migration programs

* Familiarity with DevOps, CI/CD pipelines, or automation practices
* Exposure to financial regulations and enterprise governance frameworks
Ideal for Someone Who…
- Wants to work on technically complex enterprise trading platforms
* Enjoys solving large-scale integration and platform engineering challenges
* Is looking to deepen expertise within capital markets technology
* Thrives in collaborative agile environments
* Wants strong long-term project exposure rather than short-term delivery cycles
