Fullstack Developer

Empowering merchants, enabling seamless shopping.

At Walley, we build payment solutions that power millions of smooth and secure shopping experiences every year. Our Checkout team plays a key role in this mission, ensuring that every transaction is reliable, fast, and user-friendly.

Our Checkout domain is at the heart of that mission, and we are now looking for a Fullstack Developer who wants to help us take it to the next level.

About the Role

As part of our Checkout team, you will contribute to one of Walley's most business-critical products — the checkout platform that handles thousands of transactions every day. We follow a DevOps mindset, taking full ownership from idea to production, and continuously improving performance, reliability, and user experience.

You will work in a cross-functional, autonomous team that values quality, collaboration, and learning. Every commit you make can have a real impact, both on our customers and our business.

What You Will Do

• Design, build, and maintain scalable backend services in .NET and C#
• Contribute to frontend components using React
• Collaborate closely with product managers, designers, and other developers to create high-quality, data-driven solutions
• Ensure observability, maintainability, and performance across our systems
• Take part in deployment, monitoring, and continuous improvement using modern DevOps practices

What We Are Looking For

We believe you are an experienced developer who thrives in a collaborative environment and enjoys taking responsibility for the whole product lifecycle. You are pragmatic, curious, and humble — and you care deeply about code quality, readability, and security.

You likely have:

• 5+ years of backend experience, primarily in .NET and C#
• 3+ years of experience in frontend development, ideally React
• A DevOps mindset and experience with continuous deployment and cloud-native architectures
• Hands-on experience with several of the following:
• Azure, Azure Service Bus, CosmosDB, Elasticsearch
• Kibana, Grafana
• Kubernetes, ArgoCD
• Akka
• An interest in e-commerce, fintech, or high-transaction systems

How We Work

We work in a hybrid setup, with our main office located at Lilla Bommen in Gothenburg. Three days a week we collaborate on-site to share ideas, build knowledge, and move faster together. Walley is a tech-driven, autonomous part of Norion Bank (formerly Collector Bank). Since 2005, we have been helping merchants across the Nordics grow through smarter, more flexible payment solutions.

Why Join Us

• Work with modern technology in a high-impact product area
• Be part of a humble and skilled team that values collaboration and learning
• Have autonomy and influence over tools, methods, and processes
• Help shape the quality culture of one of the Nordics' leading checkout solutions
• Ready to build and ensure the quality of the next generation of checkout experiences?

Join us at Walley, where great technology meets real-world impact.
