Job description

Everyday^ is a European home technology company building the new operating system for the new home. We're bringing together the systems that matter most — air, water, and energy — reimagined as one integrated and intelligent system designed for everyday life.

We started Everyday^ because the clean energy transition begins at home. It's where we spend most of our time, where our health is shaped, and where much of our climate impact happens. Yet more than 100 million homes across Europe still run on fossil fuels, and the systems inside them remain fragmented, complex, and disconnected.

Our first products are Air^, which heats, cools, and cleans the air in a home, and EverydayOS, the operating system that helps the home learn and improve over time.

Air^ was designed in collaboration with Bjarke Ingels Group and is powered by EverydayOS. In the coming years, we will expand our product set to include water, heating, solar, battery storage, and EV charging. We’re an experienced founding team backed by leading investors and partners, building for the long term. The people who join us today won’t simply help grow the business — they’ll help shape what it becomes.

About the Job

If you want your fingerprints on an entire platform, and your code running hardware in people's homes, this is the position for you. You'll own the TypeScript side of Everyday^ end-to-end, from design discussion through implementation and production:

• Platform and Backend The APIs and real-time services each Everyday^ home talks to: device identity and provisioning, live state, telemetry, event pipelines. Greenfield architecture; you're in the driver seat.
• The App Our customer app in React Native/Expo. We have strong design partners leading the way, but you will be owning the engineering and have a real impact on the final experience. This is the interface people touch every day, controlling their own home.
• Reliability This platform runs homes, not dashboards. You'll care about what happens when things fail, and build so they don't.
• Web Surface Our marketing platform (Next.js) is mature, documented, and tooled; you keep it sharp while the interesting work happens above.

AI at Everyday^

We're an AI-native engineering team. Our repos, docs, and workflows are built for working with coding agents, and we've invested heavily in making that fast. This is a core part of the role. How you build with AI is one of the main things we interview for. If you're the person that finds yourself arguing with the latest model, that's what we do too.

About You

You're a pilot, not a passenger. You scope your own work and outcomes. You have experience with several of the following:

• Strong TypeScript, across backend and frontend
• Production React Native and Expo, through app-store review
• AI-assisted development as daily practice — deliberate, fast, and reviewable
• Startup experience and product ownership; comfortable with ambiguity
• Clear communication. We run on good docs, not meetings.
• Fluent English (Danish not required)

The Stack

Have a better tool? The stack is not locked and can be shaped.

• TurboRepo (Monorepo), React/Next.js, Node, Vercel, Hono, Drizzle, Neon, Postgres, NATS, Railways, React Native, Expo, Sanity CMS.
• Cursor, Claude, Linear

The Gear

Expect a workstation that will make you the bottleneck not the hardware or the tokens you spend.

What We offer

• A Small Team where your architecture decisions stick and you directly shape the product
• Copenhagen Office with close collaboration
• Hybrid-Friendly after onboarding
• Real Work on software and hardware that run real homes

Contract

Full-time, based in Copenhagen, starting October 2026.
