  • About Limetax

    Limetax is building the operating system for the €20B German tax advisory industry. We acquire established tax firms and transform them into high-performing, technology-enabled businesses. We combine proprietary software, streamlined operations, and a strong group infrastructure to unlock value that traditional firm owners can't access alone.

    Our founding team brings together backgrounds in investment banking, venture building, and applied AI. We're a small, fast-moving team backed by top-tier investors. Our mandate is clear: acquire firms, make them measurably better through technology, and scale. Every person we hire has real ownership and direct impact on outcomes.

    The Role

    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.

    What You'll Own

    • 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.

    Who You Are

    • 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.

    • Have a strong bias to action and ownership. You fix things you see breaking.

    • Care more about robust systems than theoretical elegance.

    Why Limetax

    • You build foundational infrastructure, not feature churn. Your systems define how data flows across an entire profession.

    • Real production data, real users, real consequences from day one.

    • Rare opportunity to define the technical core of a category-defining company at the greenfield stage.

    • €4M+ seed funding and founders with a proven track record. You join at the moment things are being built for real.

    • Flat hierarchy, high trust, direct access to founders. No bullshit, no layers between your work and its impact.

    • Competitive compensation and early equity.

    Our Process

    We read every application and move quickly when we find the right person. There will be a few conversations and a practical case. We only make offers when we're confident it's the right fit for both sides.
