This role starts at 62,000 DKK per month and can grow up to 72,000 DKK as you develop. You’ll be part of our structured career framework, which includes regular development talks. As you build skills, take on new responsibilities and progress in your role, your salary grows with you. Our framework makes development clear and transparent, so you always know what the next step looks like.

What You Will Do

• Implement complex integration patterns, ensuring our API framework remains robust and secure even when handling difficult technical scenarios.
• Develop logic-heavy features that allow our integration marketplace to scale effectively for a global partner network.

• Ensure code reliability and performance through advanced testing and by maintaining a high standard for long-term system maintainability.
• Collaborate across Engineering, Product, and Design to evaluate feature feasibility and define the most efficient technical implementations.

What You Bring

• Professional experience in a Software Engineering role, building and maintaining scalable web applications in a production environment.

• Experience with at least one server-side language (we work with PHP) and a modern frontend framework (we use Angular).
• A disciplined approach to testing, with experience implementing patterns to ensure system reliability.
• The ability to communicate technical trade-offs clearly, providing high-level feedback to colleagues and participating effectively in technical discovery.

• Thorough pre- and onboarding to set you up for success
• A culture of ownership, trust, and independence with the support you need
• Continuous development through bi-annual growth talks and weekly check-ins
• A strong team spirit where we celebrate wins and enjoy time together across offices
