About the role
Job Description
A global transaction banking client is expanding its global liquidity management platform to onboard new clients and support transaction volumes well beyond what the current architecture can handle. Insight Global are seeking two Senior Java Developers to lead the migration of the existing monolithic platform to a scalable microservices architecture.
As a SWIFT member, the bank is subject to ongoing SWIFT regulatory change. These engineers will own the modernisation of the platform's message types to the new ISO 20022 format and keep the platform compliant as standards evolve. Alongside the re-architecture and modernisation work, they will stabilise the platform's production support function, improving reliability and cutting operational incidents as volumes scale.
This is a hands-on senior role suited to an engineer who has taken a monolith to microservices in a regulated environment and is comfortable owning delivery end to end.
Day to Day
- Decompose a monolithic liquidity platform into microservices to support higher volumes and new client onboarding
- Design and build RESTful APIs and services in Java and Spring Boot (Spring MVC, Spring Batch)
- Deliver SWIFT-driven message modernisation, migrating message types to the new ISO 20022 format
- Stabilise and harden the platform's support function, improving reliability and reducing incidents
- Write and maintain automated tests using JUnit and JMock
- Build and maintain CI/CD pipelines using Jenkins, XLR, and Ansible
- Support and optimise Oracle database interactions
- Contribute Unix and Bash scripting for automation and operational tasks
Required Skills & Experience (Must Haves)
- Strong hands-on senior-level Java development
- Spring Boot, including Spring MVC and Spring Batch
- REST API design and development
- Unix with Bash scripting
Nice to Have Skills & Experience
- Liquidity management experience (sweeping, notional pooling, cash concentration). Highly desirable
- Banking or financial services background, ideally transaction banking or payments
- Exposure to SWIFT messaging and ISO 20022 migration
- GitHub Copilot or similar AI-assisted development tooling
