Tech Lead / CTO (m/w/d)

The opportunity Tax advisory has everything automation needs: structured data, recurring work, clear rules. Yet the profession never made the leap, because recurring does not mean uniform. Every case has its own twist, and the law keeps moving. Reasoning resolves exactly this variance. That is why the window is open now. The model is no longer the scarce part. Expert knowledge and real case data are, and AI labs pay a premium for exactly this. Vogel holds what no AI-native player has: decades of accounting data, edge cases and judgment calls from several thousand mid-sized companies, audited and closed. It never leaves the house, and it becomes the edge of what you build. The market is being reordered: four in ten tax advisors in Germany leave the profession within ten years, and many of their firms will find no successor. Vogel acquires established advisory firms and develops them further, and every acquisition adds to that base. We have already produced our own annual financial statements with AI. Today, that is one person with a tool. Turning it into a capability of the whole company is the job. You own the technology that makes Vogel AI-first: the data layer above DATEV, the agent infrastructure on top, and the control layer without which nothing in this profession may go live. You decide the architecture and the stack of what we build. What it does and in which order is decided together with Operations and Moritz Vogel in the role of chief product officer, close to the advisors who use it; you shape it with them. You report to and work directly with Moritz Vogel. What you'll do Architecture above DATEV Build the data layer above DATEV. DATEV stays the system of record (for now); the value is created in the layer above it, designed to outlive the system beneath. Choose and build the agent infrastructure: framework, orchestration, versioning, observability. You answer these questions with code, not with a slide deck. Make integration a capability, not a project: every client brings their own upstream systems, and today each connection is built by hand. Build the layer those systems plug into, so what makes a client different arrives as context the agents read, never as custom code. One more client must never mean one more integration project. Reproducibility and control A tax advisor must get the same result twice, and an auditor must be able to trace it. Probabilistic where there is variance, deterministic where there are numbers. Build the control layer so that a certified professional sees within seconds what an agent did (version, source, decision) and can sign off on it. Build evaluation on decades of audited, completed work. Team and scale Make the architecture calls: design, stack, build or buy for the layer. Nobody has decided it for you, and nobody will overrule it by committee. Hire and lead the engineering team. The budget for your first engineers is approved. You start hiring in your first quarter. Make every acquired firm land on
