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 in to 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, to name but a few
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, 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 & 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
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. 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 part of your product development

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