limetax builds Germany's most modern tax advisory group - powered by a modern context and automation layer.

Your mission

Design, build, and operate the core backend platform that powers LimetaxOS - our operating system for tax advisory firms.

You will unify deeply fragmented legacy systems - accounting software (DATEV), banks, documents, emails - into a reliable, extensible, production-grade platform that scales across dozens of firms. The systems you design will define how data flows through the organization, how workflows execute reliably under real-world constraints, and how AI can be applied safely and effectively on top.

How your day-to-day will look

• Design, implement, and operate core backend services across accounting, payroll, reporting, and compliance.
• Build robust data pipelines to ingest, normalize, and reconcile data from DATEV, banks, and document sources.
• Design workflow orchestration for long-running, stateful, failure-prone processes.
• Own correctness, observability, and performance of the systems you build.
• Make pragmatic architectural decisions in a true greenfield environment.
• Ship to production frequently - your code runs in real tax firms from day one.
• Work directly with the CTO on system design and core technical decisions.

Is it you we're looking for?

• Have built and operated production backend systems before (language-agnostic; TypeScript-heavy today).
• Are comfortable designing systems around data integrity, workflows, and reliability.
• Enjoy going deep on complex, messy, real-world problems.
