Backend Engineer

We're at a pivotal moment for both Tibber and the planet. When joining Tibber, you won’t just help scale a forward-thinking tech company – you’ll contribute to a real shift in how people consume electricity. With millions of smart devices connected to the Tibber platform (like electric vehicles and smart thermostats), we have one of the most unique portfolios trading energy on the market.

Job Mission

As a Backend Engineer, you'll play a key role in turning our trading models into robust, production-ready systems - helping Tibber trade smarter so we can pass better prices and a more reliable energy experience on to our customers. You'll work closely with our forecasting team, right where trading decisions meet real customer impact.

What you'll do ✅

• Build forecasts that support Tibber's trading operations

• Bridge model development and production-ready backend systems, working closely with the team building our ML models

• Support both our retail trading and flex trading domains

• Work hands-on with time series data

• Collaborate closely with traders who act on your systems' outputs daily

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:

• Have strong Python skills and experience building backend systems in ML-heavy environments (production ML, not just notebooks)

• Have hands-on experience with time series data and forecasting

• Know how to move ML models from development into reliable, production-ready systems

• Are proactive and entrepreneurial, comfortable owning your work end-to-end in a small, high-impact team

• Communicate well with both technical peers and business stakeholders

• Have a background in energy, utilities, or financial markets, or experience with .NET — a plus, but not required

• Tibber becomes more AI-enabled and we embrace new tools and ways of working. You don't need to be an expert, but we believe you are motivated by that and excited to grow with it too

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 - from electric vehicles to smart thermostats, all connected to the Tibber platform. We strengthen the resilience of the grid. Not in theory. In everyday life.

We win, fail, and grow together, staying curious and pushing for better every day. AI is shaping how we work - and we're on a journey to make it central to everything we do. The further we go, the more our Tibberinos matter - and yes, that's what we call ourselves!

Started by two founders in 2016. Now 300+ Tibberinos across Stockholm, Oslo, Berlin, Amsterdam, and Førde. And we're still just getting started.

You're welcome at Tibber for who you are. We hire for what you can do and how you think - not your background or where you've been. Diverse teams build better products, and we mean that.
