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 energy trading portfolios on the market.
We're looking for a german speaking Backend Engineer to join us in making the energy transition happen – maybe that's you?
Job Mission
As a Backend Engineer at Tibber, you'll play a key role in
powering Tibber's integrations with the German energy market
— a critical enabler for helping households use energy smarter and greener. You'll design and operate services that process millions of market transactions reliably and at scale, ensuring Tibber stays compliant and competitive in one of Europe's most dynamic energy markets by combining solid engineering practices with a deep understanding of its ecosystem, practices, and workflows. Your work will directly support our mission to make sustainable energy usage effortless for our users.

What You'll Do

• Collaborate in a small, close-knit backend team — working daily with your Product Manager as part of the team — and partner cross-functionally when needed to evolve integration capabilities and tackle complex data flows.
• Implement and maintain EDIFACT message flows (e.g. UTILMD, MSCONS, INVOIC) in line with BDEW specifications, analyzing updates and implementing required changes to ensure compliance and optimize workflows for performance, conversion, and reliability.
• Build and scale backend services that process millions of transactions in the German energy market, using a modern stack (dotnet, TypeScript, Kafka, Kubernetes, AWS, Postgres) in a microservices architecture.
• Take full operational ownership of the services you build — from monitoring and incident management to continuous improvement.
• Shape Tibber's technical direction by contributing to architecture discussions and long-term decisions that strengthen our position in the German market.

What We're Looking For
A
skilled backend engineer
with experience designing and running large-scale distributed systems. You are:

• Fluent in German and English, comfortable navigating both technical and regulatory discussions.
• Based in Berlin (or willing to relocate) and ready to work closely with our local market experts.
• Excited — or at least curious — to dive deep into the German energy market and master its EDI/BDEW standards.
• A proactive, self-driven problem-solver who thrives with autonomy, communicates transparently, and collaborates constructively across teams.

Bonus points if you have experience with EDIFACT/BDEW messaging, the energy sector, or other highly regulated/high-volume transactional systems (e.g., finance, telecom).
The Tibber Mindset
Tibber is not your typical energy supplier. Our tech helps hundreds of thousands of households lower and shift their energy consumption to more sustainable and affordable hours. We're here to accelerate the energy transition – not in theory, but in everyday life.

Being on a mission to change an industry, fundamentally also means being prepared for the unexpected. We do what others say can't be done, try and fail together but never lose sight of our users. We work passionately with sustainability and a circular approach, both with our own products and in the entire ecosystem that is affected by everything we do.

Starting out with two passionate founders in 2016, we're now 300+ people working for Tibber in our offices in Stockholm, Førde, Berlin, Amsterdam, Oslo, and Helsinki. We will continue to grow within our markets, and we are thrilled to be backed by investors like Balderton Capital, Eight Roads Ventures, Founders Fund, Summa, and Schibsted.

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?
