We’re now expanding our engineering team in Sweden to lead the way forward.

We’re looking for a Senior Software Engineer who thrives on building real products, enjoys working across backend, frontend, and AI, and wants to be part of a fast-moving team where architecture, quality, and user experience matter.

• Background in architecture, scalability, and CI/CD

• Genuine curiosity about AI and how it's changing software development, ideally with hands-on experience of AI-assisted development

• You work in a structured way and understand that high speed requires order, not chaos

• You can move between architectural thinking and detailed implementation

• You communicate clearly, take ownership and thrive in a fast-moving environment
