Your role in the team
- 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.
- In close collaboration with other teams, you'll design scalable backend systems and help shape technical direction as part of a small, high-ownership team that moves fast without cutting corners.
- This is a role for someone who loves building things that matter - and who takes genuine pride in the craft of doing it well.
- Build, maintain, and continuously improve core shared services and internal tools that power stable, intuitive user experiences for both Taxfix and Steuerbot.
- Design and implement scalable, reliable backend systems and architecture that enable core functionality across Taxfix and Steuerbot.
- Collaborate across teams to design, ship new features and share capabilities, working pragmatically beyond the boundaries of your immediate team.
- Contribute to shaping the long-term technical direction of core backend services, bringing both depth of expertise and a pragmatic, outcome-focused mindset.
- Contribute across the team's stack, including occasional frontend work on internal tooling.
- Take ownership, remove blockers, and help the team stay focused on what matters most.

Our expectations of you
Qualifications
- 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.
- You're collaborative, direct, and outcome-oriented, and thrive in cross-functional environments where people work closely together to solve problems.
- German language skills are a plus, as this team works closely with Germany-specific tax logic.
Experience
- You bring strong backend engineering experience and a proven track record of building and evolving complex, scalable systems in production environments.
- You are highly proficient in at least one modern programming language, and experience with Go is strongly preferred.
- 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.
