We are Tibber, the energy company that wants you to use less energy. Whaaat? That’s right. We’ll get back to that. Yes, we are by definition an energy company, but we’re more techy than most. How and why you might ask? Well, a third of our employees are actually working on developing products and solutions that can help you use energy in a smarter way and at a lower cost – all with the help of cool fancy tech. Good for our customers, their wallets, and the planet.

Our growth rate has been truly amazing, and still, we’re just getting started. 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 🚀

The Invoicing squad is an essential part of Tibber’s Energy Deal product area. Our mission is to create efficient, automated systems that handle invoicing, payments, and dunning processes, ensuring seamless operations and a positive experience for everyone engaging with our energy deals.

As a Senior Backend Engineer, you’ll work closely with a collaborative and talented team of engineers and market specialists to enhance payment processes and streamline debt management. Your work will contribute to smoother operations, reduce manual workloads, and elevate the experience for all users, playing a key role in Tibber’s impact within the energy sector.

What you’ll do 💻

Design, develop, and maintain scalable backend systems within a cloud-based microservices architecture using dotnet and TypeScript, ensuring the platform reliably supports high transaction volumes across multiple markets.

Improve invoicing, payment workflows, and dunning processes to efficiently manage millions of transactions, easing workloads for back-office and support teams while enhancing the user experience.

Integrate with banks and external services for invoicing, payments, and dunning, ensuring smooth operations and compliance with local regulations across diverse markets.

Partner with cross-functional teams to refine workflows, introduce innovations, and contribute to technical excellence across Tibber’s platform.

Stay curious and informed about emerging trends, offering ideas to enhance architecture, scalability, and regulatory compliance.

Iterate and refine solutions based on user feedback, team insights, and the evolving needs of the energy sector.

What we’re looking for ⚡️

We’re looking for a skilled Senior Backend Engineer who enjoys collaborating in agile environments and is passionate about creating thoughtful, user-focused solutions. Here’s what we value:

Technical Expertise. Strong experience building scalable backend systems in high-transaction environments. While we use dotnet and TypeScript, we welcome engineers with a foundation in modern backend languages and familiarity with cloud platforms (e.g., AWS, Azure, or GCP), container orchestration, and distributed systems.

System Ownership. Experience guiding projects through their full lifecycle, ensuring they are robust, scalable, and meet long-term goals.

Financial Domain Knowledge. Ideally you should have understanding of financial workflows, with experience working on invoicing and payment systems that span multiple markets.

Collaboration and Mentorship. A supportive team member who enjoys sharing knowledge, nurturing others’ growth, and working across teams to help foster our supportive and empowering environment.

Creative Problem-Solving. A thoughtful approach to improving systems, embracing opportunities to refine processes and adapt to feedback.

Adaptability. A proactive, self-motivated person who is open to learning, contributing new ideas, and helping systems and processes evolve to meet changing needs.

💆🏻‍♀️💆🏽‍♂️The Tibber Mindset

Being on a mission to change an industry as we do fundamentally also means being prepared for the unexpected. Tibber is a startup in the word's true sense, which means we are on a journey of constant change. 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.

We're very proud of being a mission-driven startup with thousands and thousands of new users every month. 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, and with that number growing each week, we’re still just getting started. Throughout 2025, 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.

At Tibber, we are committed to hiring, developing, and retaining exceptional people regardless of race, color, religion, sex, sexual orientation, age, marital status, disability, neurodiversity, or gender identity. We strongly encourage people from underrepresented groups to apply.
