Job Description

About the role

Currencycloud was acquired by Visa in December 2021. Our Senior Software Engineers are responsible for implementing an industry-leading API that has already processed over 50 billion USD of cross-border transactions for over 5 million end users, and is available to our clients 24x7. But we’re not stopping there, and our engineers are at the forefront of taking us forward to meet the demands of even greater scale.

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.

What you'll get to do:

• You’ll play a key role within your cross functional team, taking responsibility for your services and the technology within them.
• These roles fit into squads who are building out brand new parts to our payments platform, focusing on high availability, cloud native, microservice concepts.

You'll get:

• Clear ownership of your domain.
• A clean modern codebase.
• An independent path to production.
• Strong platform and product support.
• The ability to make real changes with real business value.

Our Tech Stack includes:

• Object-oriented programming forms the bulk of our codebase, currently in Java, versions 11+, and ideally Springboot framework.
• Highly-scalable, highly-available, cloud-native applications on AWS are key to our next phase of growth, are 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, ElasticSearch, 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 datastores.
• 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.
• Agile development, with teams broadly aligned with the Spotify - Squads & Tribes - model, helps us deliver incremental improvements to our products in an iterative manner.
• Continuous Integration and Continuous Delivery pipelines allow us to “automate all the things”, providing repeatable builds and consistent deployments.
• GitHub, and the GitHub 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.

This is a hybrid position. Expectation of days in office will be confirmed by your hiring manager.
