Job Description

Currency cloud was acquired by Visa in December 2021. Our Senior Software Engineers play a key role in building and evolving an industry‑leading API that has processed over 50 billion USD in cross‑border transactions for more than 5 million end users, and is available to clients 24×7. As we continue to scale, our senior engineers are at the forefront of driving technical direction, shaping architecture, and ensuring our platform meets the demands of ever‑growing global usage.

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:

• As a Senior Software Engineer 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 maintaining and building out brand new parts to our Payments Platform, focusing on high availability, cloud native, microservice concepts 
• You'll get to work as a Senior Engineer in your squad, leading on discussions around technical direction and systems design, as well as mentoring more junior members of the team 

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 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 
• 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 

Visa requires at least 3 days in office, expectations of these days will be confirmed by your Hiring Manager.

Qualifications

• Skills with functional Java (versions 8+) and Spring (ideally Springboot)
• Agile ways of working such as Scrum or Kanban in cross-functional teams
• Expert knowledge of Docker, EKS, AWS (public cloud) and Kafka.
• Ability to communicate equally effectively with both technical and non-technical stakeholders.
• Modern Cloud-Native architectures and practices. To name some: high-availability, high-scalability, microservices, 12-factor apps, Event-driven architecture CI/CD, heavy testing automation and observability.
• TDD, BDD and Contract testing.
• Working in a DevOps environment, or passion and willingness to work in this way.
• Proven delivery of well-tested, scalable, fault-tolerant and performant solutions.
• A pragmatic approach to solutions and delivery of technical projects.
• A self-starter who takes accountability for getting things done.
