We are looking for a Senior Software Developer to join our distributed engineering team and play a key role in building the payment solutions of the future. You will work on our .NET microservices backend — primarily hosted in Azure, with Corniche as our API‑driven core banking system at its heart — collaborating with engineers across Borås, Stockholm, Gdansk, Málaga, and the Czech Republic. This is a hands‑on, high‑impact role where you will contribute to technical direction, share knowledge across the team, and help shape our platform and engineering culture.

Key Responsibilities

• Lead the design and development of microservices and their architecture using .NET Core
• Drive cloud‑based solution design, ensuring robust, scalable, and reliable services on Azure Cloud Native
• Oversee CI/CD pipelines and deployment workflows using Kubernetes, Docker, and Azure Pipelines
• Optimize systems and applications for high performance, reliability, and maintainability
• Implement and improve logging and observability using OpenTelemetry
• Share knowledge and support developers of varying seniority, contributing to technical and architectural discussions
• Collaborate across distributed teams and ensure alignment on technical strategy and best practices

What We're Looking For

• 5+ years of software engineering experience with strong expertise in C#, .NET Core, and Azure
• Proven experience with transaction‑intensive systems and agile development processes
• Deep understanding of microservices architecture and distributed system design
• A collaborative, team‑first mindset with a passion for engineering quality
• Fluent in English and Swedish
• Experience in e‑commerce, payments, or finance is a plus, as well as familiarity with systems like Corniche or Mambu

What We Offer

• A hands‑on technical role with real impact on platform architecture and direction
• The opportunity to work on a modern, unified payment platform serving 14 European markets
• A collaborative, distributed team with a strong engineering culture
• Growth opportunities both technically and professionally
