Full-Stack Engineer

Copenhagen

• Full-time
• On-site

At Float, we are on a mission to build the world's first Agentic Home Platform, starting with the first Agentic Consumer Energy Company — because energy is fundamental to homes.

Float is a Copenhagen-based and venture-backed startup with a senior team. We have a full-stack AI approach to our product and our way of working.

We're always looking for great and talented people so please reach out if you can see yourself in this type of role.

The Role

You'll Work Across The Entire Product

• Customer-facing app (real-time energy insights, billing, notifications)
• Internal ops systems (onboarding, compliance, energy data flows)
• APIs and backend services powering our AI-driven platform
• Integrations with national energy infrastructure (DataHub, BRP, etc.)
• Agentic workflows that automate what traditional utilities run with staff and call centers

You will ship real features to real users — fast.

What We're Looking For

You

• Have 3–8+ years of experience building production systems
• Are strong in both frontend and backend
• Care about clean architecture and performance
• Like ownership and responsibility
• Thrive in small, fast-moving teams

Typical Stack Experience Could Include

• TypeScript / Node.js
• React / Next.js
• Python (bonus)
• PostgreSQL
• Cloud infrastructure (AWS/GCP/Azure)
• API design (REST/GraphQL)

You don't need all of this — but you need to be able to learn fast.

Why Float

We are not building "just another SaaS tool, but now with AI".

We Are Building

• A fully automated energy provider
• An AI-first operating system for the home
• Infrastructure that must be correct, compliant, and scalable

Energy is critical infrastructure. And we're rebuilding it from scratch.

Practical Details

• Location: Copenhagen
• Start date: Depending on an assessment of skills, fit and roadmap
• Compensation: Competitive salary + equity options
