Berlin - Engineering

As one of the most successful FinTech companies in Europe, Taxfix is an exciting place to work. We’re revolutionizing filing taxes – and saving people money, time and stress by putting a personalized digital tax consultant in the palm of their hands.

In just 2 years, Taxfix has raised €42 million from some of the best investors in the world.  We achieved this by putting our customers at the core of what we do and helping them save millions of euros every week.


Our Mission

Our mission is to help people get their maximum tax refunds in a convenient, transparent and timely manner, hassle-free. Our user-friendly Taxfix App enables people to file within 25 minutes, without any prior tax knowledge or complicated forms.

Our talented team creates products that help people improve and simplify their lives. Our diverse group of over 80 people come from over 20 nations, with a shared a passion for product development and creating an outstanding user experience. Join a team of smart, ambitious, driven people who value open communication and processes.


Our Tech Environment

The tax industry is outdated and we have embraced the disruption we can cause here by innovating and thinking outside of the typical "Tax box". We have created our own modelling language - TaxML so our tax experts can focus on designing user journey, while developers can focus on improving the product.

Our Tech stack is React and React Native on the frontend, NodeJs and Elixir on the backend. Everything is running in Docker, orchestrated by Kubernetes and powered by Google Cloud Platform. We are big fans of decentralised end-to-end ownership, cross-system contracts, internal open-source and data-driven decisions.

Our cross-functional teams have full exposure to all of the tech, and we support your development with the areas you want to grow. We have introduced internal Tech communities where you can join the one that excites you the most! We hire for your values and drive to learn - not just your technical skills, we love to foster growth from within.

We love to welcome the Berlin Tech community to our home here at Taxfix for Meetups and events.
