Sr Java Software Engineer

Overview:
In Corporate and Institutional Banking (CIB) we are building in-house solutions to carry out the post-trade activities. Our businesses generate millions of transactions across a range of financial markets.  Our IT teams design and develop modern systems covering all aspects – trading in the markets, sales and customer tools, handling transactions and building financial and regulatory reporting.

The team:
You will join new Toronto-based team, responsible for the development and support of FX Post Trade back-office systems. The local team collaborates with broader organization of 60+ professionals located around the globe in Guangzhou, Hong Kong, Pune, London and Toronto. We deliver multiple changes to production each week with a flexible Kanban-like and agile process that evolves over time.

The project:
We are working on an application OPAS (Operation Platform As Service), which is an in-house developed application for Global Market Operations to fulfil business daily operations requirements.

The vision of OPAS is to have:

• Achieving ultra-scalability without sacrificing performance and availability
• Breakdown into components and take efforts to decentralize change management and providing teams with more control over how features make their way to production
• Distributed and move away from vertically scaled infrastructure and single points of failures

Not only needed to transform the way we build and operates on a post trade system, and it needed to transform the culture of GM operations.

Our teams are currently operating in micro services environment based on Java 17 and 21, Vertx and using a vendor product. Those micro services interact with various upstream and downstream systems. We will build the UI for OPAS HTML5, Javascript and ReactJS and the platform integrates with other systems in the Bank using a combination of MQ, File, Web Service and REST interfaces.

Key accountabilities:

• You and your teammates are responsible for all aspects of delivering software to your users:
  • Development of new requirements

  • Speaking to product owner and business on features and requirements
  • Deploying changes to production frequently and confidently
  • Production availability of your service – if you build the service you own the service!

Key Responsibilities:

• Develop and maintain scalable and secure microservices using Java 17+, Spring Boot, and Vert.x
• Provide production support for critical applications, following incident management protocols

We offer:

• All our teams work in ‘pods’ of 4-8 developers and work closely with a business Product Owner.
• We are not ‘order takers’ but responsible for the service we are developing.
• For us that means:
  • All our teams strive to do continuous delivery – we do small, incremental releases and follow agile practices.
  • We are empowered to use technology and tools to automate as much as possible.
  • We build small services and strive to break up monolithic systems where we have them.
  • Each small team is responsible for everything from the requirements to the development to running it in Production
