Currencycloud was acquired by Visa in December 2021. Our Staff 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.

This role will support the entire Customer tribe and work across multiple teams and domains, including account and contact management, reporting, wallets and balances, end‑client onboarding, and notifications. It’s a large area with very multiple technical challenges, mainly revolving around event‑driven architectures and working at scale.

This is a hands‑on individual contributor role at a senior level where you’ll lead technical widespread strategy, mentor senior engineers, and ensure alignment with organizational standards. Beyond delivery, you’ll influence how other teams adopt event‑driven principles and modern streaming practices, acting as a trusted technical authority across domains.

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

• Own the technical vision and roadmap for services, ensuring they are robust, performant, and easy to consume by other teams.
• Lead design and implementation of streaming solutions using Kafka, Flink, and related technologies.
• Collaborate with product and engineering teams to understand requirements and deliver platform capabilities that accelerate their development.
• Drive best practices for observability, reliability, and scalability in distributed systems.
• Mentor and support engineers within the team, fostering a culture of technical excellence and continuous improvement.
• Act as an evangelist for event‑driven architectures – implement them, communicate their benefits, and champion adoption across the organization

• Clear ownership of technical vision and architectural standards for a critical domain.
• Opportunity to influence and shape a new team from the ground up.
• A modern tech stack and autonomy to innovate.
• Strong organizational support and visibility for your work.

• 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, Elastic Search, 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 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.…
