Senior Software Engineer RDPT

Job Description

Currencycloud was acquired by Visa in December 2021. Our Realtime Data Platform Team is a newly formed group focused on enabling and supporting real‑time data capabilities across the organisation. This team provides foundational services such as Apache Kafka, Kafka Connect, Apache Flink, and other streaming technologies that power real‑time applications and data flows.

As a Senior Software Engineer, you’ll be a key contributor to building and maintaining these platform services. You will work on designing and implementing solutions that ensure reliability, scalability, and ease of use for other engineering teams. This is a hands‑on role where you’ll collaborate closely with peers, contribute to technical decisions, and help shape best practices for real‑time data systems.

Our stack runs on AWS as a set of distributed applications using Kubernetes and a microservice‑led architecture. We are also utilising Kafka for our streaming and PACT for Contract testing.

• Design, develop, and maintain streaming infrastructure and services using Kafka, Flink, and related technologies.
• Build tools and frameworks that make it easy for other teams to consume real‑time data capabilities.
• Ensure high availability, scalability, and observability of platform components.
• Collaborate with cross‑functional teams to understand requirements and deliver solutions that meet organisational needs.
• Contribute to continuous improvement in code quality, testing, and deployment practices.
• Act as an evangelist for event‑driven architectures – implement them, communicate their benefits, and champion adoption across the organisation.

• Ownership of critical components within the real‑time data platform.
• Opportunity to work with cutting‑edge streaming technologies.
• A modern tech stack and autonomy to innovate.
• Strong organisational support and visibility for your work.

• Object‑oriented programming forms the bulk of our codebase, currently in Java 11+, and ideally Spring Boot.
• Highly‑scalable, highly‑available, cloud‑native applications on AWS are key to our next phase of growth, written to 12‑factor principles and fit into our microservices architecture.
• Cloud‑related tools, services, and distributed system observability to support these applications, such as Docker, Kubernetes, Elastic Search, log management systems, and Datadog APM.
• API specifications, conforming to the OpenAPI (Swagger) standard, provide a clean boundary both externally between our customers and our product, and internally between our microservices.
• SQL, and large SQL databases, provide the persistence layer for our applications. You’ll be working with (and know the limitations of using) such large data stores.
• Infrastructure automation is primarily owned by the infrastructure team, but you will be a consumer of their work; familiarity with AWS, Terraform and Docker is beneficial.
• Testing approaches, including TDD, BDD and Contract Testing, all form an important part of our approach to quality assurance, ensuring that the code that we write forms products that are fit for use. We currently use a variety of frameworks including JUnit, RSpec and Cucumber.
• Agile development, with teams broadly aligned with the Spotify – Squads and Tribes – model, helps us deliver incremental improvements to our products in an iterative manner. Advocating this model, and joining us on a journey of continuous improvement, is a key attribute of members of our teams.
• Continuous Integration and Continuous Delivery pipelines allow us to automate‑all‑the‑things, providing repeatable builds and consistent deployments.
• Git Hub, and the Git Hub PR review process, forms a core part of our developer workflow, and peer reviews help share knowledge and improve quality.
• Teamwork, and cross‑team collaboration, is fundamental to the delivery of our applications. Whilst each application has an independent path to production, there will always be some activities and initiatives that span multiple teams and require cross‑team collaboration. Within your team you’ll need to collaborate with a number of stakeholders, including Product Owners and QA, as…
