Fullstack Engineer

We're Tibber - the energy company that wants you to use less energy.

When you join Tibber, you'll be part of building the tech that creates a real shift in how people consume electricity - good for our users, their wallets and the planet. We believe AI is how we accelerate that shift, and it's our people who lead it. The more we lean into AI, the more human judgment, curiosity and creativity matter.

We're looking for a Fullstack Engineer to join us - maybe that's you?

Job Mission

As a Fullstack Engineer, you’ll play a key role in electrifying our customers’ homes, helping them save money and use energy more sustainably. We’re growing our Electrification team with two engineers: one focused on the software tools our installers use, one on our online hardware store. Both report to the team’s Engineering Manager.

What you'll do

• Ship features end to end, working closely with your PM and designer.
• Co-own the team's codebases with the engineers already there, and keep them healthy as we grow.
• Help the team move to agentic development, making AI a natural part of how we build.
• Talk to stakeholders and turn their needs into technical requirements, together with your PM and EM.
• Installer focus: Build the tools installers rely on in the field, from our React Native app and its gateway to a new web presence in Next.js.
• Ecom focus: Build and improve Tibber's online hardware store in Next.js, and the services behind it. Right now that means checkout improvements and agentic features.

We'll find the focus that suits you best together during the process.

What we're looking for

You are driven by impact and know how to turn strategy into execution. You're used to fast-paced environments and thrive when given clear goals and high accountability.

We believe you'll thrive here if you:

• Are strong in JS/TS and Node, and hands-on with React and Next.js. React Native, Expo or an ecommerce background is a plus.
• Have built or worked on event-driven systems.
• Are comfortable working in AWS, with tools like Kubernetes, Terraform, CircleCI and ArgoCD.
• Enjoy working closely with designers, PMs and fellow engineers to build great user experiences together.
• Are humble and transparent, and a generalist who enjoys covering many areas.
• Want AI in your daily dev loop. Tibber is becoming more AI-enabled, and you're excited to help our team make that shift.

Don't tick every box? We'd still love to hear from you. If this sounds like the role you want to grow into, apply!

The Tibber Mindset ‍️‍️

Tibber exists to drive energy independence - away from fossil dependency. Our tech helps hundreds of thousands of households shift their electricity consumption to more sustainable and affordable hours, strengthening the resilience of the grid. Not in theory. In everyday life.

Being on a mission to change an industry means being prepared for the unexpected. We do what others say can't be done - and we do it together. We win, fail and grow together, staying curious and pushing for better - every day. AI is shaping how we work - and we believe it's how we accelerate the energy transition. The more it becomes part of how we operate, the more our Tibberinos matter.

Started by two founders in 2016. Now 300+ Tibberinos across Stockholm, Berlin, Amsterdam, Oslo and Førde. Backed by Balderton Capital, Eight Roads Ventures, Founders Fund, Summa and Schibsted. Still just getting started.

Diversity of thought fuels better products, so we welcome applicants of every background, identity and lived experience. Ready to be part of powering the energy transition? Apply below!
