Product Engineering
Our intuitive app enables anyone, regardless of education or background, to file their taxes with newfound confidence.
We speak our minds openly, and with over 400 professionals, including tax experts, developers, and IT security experts, we're rich in ideas and voices. As a (Senior) Software Engineer on the TaxCore team, you'll be part of a shared engineering team that serves both Taxfix and Steuerbot - one team, two brands, multiple products. Based in Berlin or Stuttgart with a flexible hybrid setup, you’ll build and evolve the core shared services that power core experiences across both brands. This is a role for someone who loves building things that matter - and who takes genuine pride in the craft of doing it well.
Contribute across the team’s stack, including occasional frontend work on internal tooling.
You bring strong backend engineering experience and a proven track record of building and evolving complex, scalable systems in production environments.
You have solid experience with modern software architecture concepts, including API design, databases, and cloud-based systems - and hands-on experience integrating a diverse range of third-party and internal APIs.
You are comfortable with containerization and DevOps concepts, with practical experience using tools like Kubernetes.
You care deeply about code quality - writing performant, maintainable, and elegant code is something you take genuine pride in, and you have a natural affinity for the full stack of what it takes to ship great software.
You are familiar with AI-assisted development tools like Claude Code, and understand how to use them thoughtfully to support better, faster engineering.
You’re a pragmatic, hands-on builder: someone who cuts through complexity and enjoys turning ideas into well-crafted solutions.
German language skills are a plus, as this team works closely with Germany-specific tax logic.
