Job description

Do you want to take an active role in building the payment processing engine that enables instant transfers across the world, all hosted in the cloud? Join a dedicated small team with focus on high-value features that are central to the strategy of the bank.

Banking Circle is a fully licensed, technology enabled bank processing over €1,5 trillion in payments every year - and growing. We exist to power the global economy’s most ambitious payments businesses with infrastructure that is fast, modern, and engineered for scale. Today, more than 800 people across 11 countries work together as one global team. We move fast, we think boldly, and we build with intent - because our clients depend on us to keep pace with the world’s most dynamic payments flows. We are expanding globally, scaling our capabilities, and deepening our impact, so if you want to shape the future of financial infrastructure - this is the place.

Your team welcomes you with open arms

As our new Development Engineer in the Core Payments Team in Copenhagen, you’ll experience an open and knowledge driven culture, where everyone can thrive, connect with colleagues, learn and grow. Here you will be empowered to make an impact every day.

You will participate in building a high-end solution where quality, performance, and reliability matters and where we have ambitions for our payment engine to become a central enabler of the company’s future abilities and opportunities.

By joining the team, you will get the chance to build and support a payment engine that enables 24/7 processing and meets demands for continuous high throughput. We are a .NET backend-team that uses a mix of technologies with a focus on the Microsoft Azure-suite, e.g. with Azure Data and Messaging Services (Service Bus, EventHub, etc), and use of Azure DevOps (Pipelines, Repos) hosted in the cloud (Kubernetes).

We are an agile team that has a close collaboration with stakeholders and where there is a high level of trust in, and recognition of, the team’s capabilities.

We offer a hybrid work model for our employees to allow for flexibility and productivity. However, we do expect you to spend most of your time in the office to build community and efficiency in the team.

Exciting work is waiting for you

• Development of back-end solutions in C# on Microsoft Azure (Azure SQL Database, Service Bus, Storage Accounts, KeyVault, Kubernetes, etc.).
• Applying good engineering practices with an eye for performance and reliability
• Carry the technical responsibility of complex feature implementations
• Critically assess our way of working and contribute to improving and maturing it
• Critically assess the current solutions, and contribute with ideas to continuously improve and scale of our platform
• Support our ways of working and be a contributor in improving and maturing them

Things we’ll look for on your resume

To succeed in this role, we expect you to already have experience from a similar role where you have gained experience within .NET. You might already have worked with backend solutions that process high volumes of data with a focus on throughput and availability.

You have experience working with performance sensitive applications and you are comfortable with caching strategies, both in-process and distributed. We run our entire core platform in Azure so you will get a chance to work with modern cloud services and solutions. Therefore, Azure experience is a definite plus, but not a requirement.

You are motivated and skilled in designing clean and maintainable solutions.

As a person you are pro-active, responsible, and quality oriented. You have strong analytical skills and a structured way of working and courage to try new things. You are dependable and a knowledge-sharing team-player that thrives with collaboration.
