Fullstack Engineer

Our Story

At Taxfix Group, our mission is to make taxes effortless and accessible for everyone. Across our brands (Taxfix, Steuerbot, and TaxScouts), we’ve helped over 400 professionals simplify the tax process and enabled customers to reclaim more than €3.5 billion since 2016.

This role sits with Steuerbot, a Stuttgart-based brand within the Taxfix Group. The app guides users through their tax return in a friendly chat format using clear, personalised questions that make filing simple — no jargon, no stress. We believe everyone should be able to do their own taxes and get the most out of their refund, regardless of income or background.

We move fast, learn from mistakes, and build solutions that empower millions through a passionate team that values fairness, autonomy, and data-driven thinking. If you’re excited to shape the future of tax tech as part of a collaborative, mission-driven team, we’d love to meet you.
