Job description

Fullstack Developer - Proptech / AI (Stockholm, On-site)

We're working with a newly founded Stockholm proptech company building a data and AI-driven analytics platform used by banks to assess commercial real estate. They launch with committed institutional backing and a first, large customer already secured - so the commercial foundation is in place before the product ships.

This is a permanent Fullstack Developer role in central Stockholm, joining a small engineering team at the very start.

What you'll work on

• Building a greenfield .NET platform from the ground up, with no legacy debt to work around
• Developing across the full stack - .NET backend with a modern React frontend
• Designing and building event-driven services in Azure
• Working with data pipelines, orchestration and data lakehouse architecture as the analytics platform develops
• Owning deployment and pipelines alongside the CTO
• Shaping the product and technical direction directly, rather than one small corner of it

What we're looking for

• Around 5+ years' professional experience, though demonstrated skill matters more than years
• Strong .NET - the platform is built on it
• Experience with Azure
• Modern frontend, ideally React
• Comfortable with AI-assisted and agent-driven development - the team is aiming for a fully agent-driven workflow
• Someone genuinely invested in building something long-term
• Suited to a small company where each person has real impact, comfortable without the structure of a large organisation
• Swedish Fluency is required for this position

Why this role?

• Funded startup in a serious market, with the majority owner also acting as first customer
• Ground floor of a company backed to scale - one of the first engineering hires
• Genuine ownership and influence over the whole product
• Greenfield build on modern technology
• AI-native engineering culture, where agent-driven development is the goal rather than a side project
• Technical, hands-on CTO leading the engineering side
