Job summary

Rumli is building a full-service property operator powered by AI. We’re shipping production software with AI agents as part of the development workflow, and the codebase uses TypeScript across the stack. You’ll shape the platform architecture, own features end-to-end, and ensure scalability across the Nordics.

The role emphasizes working directly with the co-founder, shipping fast with iterations, and embedding AI deeply into core product features. Copenhagen-based on-site work is required.

Qualifications

• Strong TypeScript/Node.js skills.
• Experience with full-stack development (backend + React).
• Experience with AWS and scalable architectures.
• Experience with AI-powered features or agents is a plus.
• Ability to design and implement scalable platform architecture.

Responsibilities

• Shape the architecture of a platform being built from scratch.
• Own features end-to-end — database to API to UI.
• Ship fast — mockups, prototypes, iteration.
• Make architectural decisions that scale across the Nordics.
• Build AI into core product features.
• This isn’t a ticket-taker role; solve messy problems and decide what to build.
