Fullstack Engineer (m/f/d)

Berlin - Engineering

Our story:


Every year millions of people are either filing their taxes in fear or giving up on their tax refund altogether. We're working on fixing that. Our intuitive app enables anyone, regardless of education or background, to file their taxes with newfound confidence.


Spread across Berlin and Madrid, Team Taxfix is a compassionate group of solution-finders. We speak our minds openly, and with 250+ professionals from 40 different nationalities, we're rich in ideas and voices. In four years, we've raised over 100 million euros in funding and helped people reclaim more than 400 million euros. 

Your team:


We believe in Internal Open Source because it cultivates a strong spirit of collaboration and fast evolution while maintaining a high standard of quality. This way of working is made possible by using the universal language JavaScript, specifically, React, React Native and NodeJS. We also utilise Elixir in the reasoning engine used to write our tax logic. Everything runs in Docker—orchestrated by Kubernetes and powered by Google Cloud Platform.

Our cross-functional team structure gives developers a broad scope of our stack. We're passionate about decentralised, end-to-end ownership and deep collaboration. We live our development values by learning from one another through internal meetups, hackathons, and dedicated tech communities.
