Job Description

milia is the AI-powered all-in-one platform for German tax advisory firms: workflow management, client portal, document intelligence, and DATEV integration — all in one system. Our AI layer, milia.AI, is not a feature. It's the core of the product.
We're looking for a Senior AI Engineer to help build, own, and scale it.

WHAT YOU WILL BUILD

• Agentic Workflow Engine: autonomous, multi-step workflows for tax processes (documents, deadlines, client communication)

• Document Intelligence: extraction, classification, and analysis of tax-relevant documents (P&L statements, receipts, DATEV exports)

• Tool-Calling & Custom Prompt Library: structured LLM usage across internal and external APIs
  DATEV API integration with semantic processing of financial data

• Real-time financial analysis features (P&L analysis, liquidity planning, KPI dashboards)

WHAT YOU BRING

• Production-level experience with LLM integration (OpenAI, Anthropic, Gemini — API-level, not just wrappers)

• Proficiency in tool use and function calling, RAG architectures, prompt engineering at scale

• Experience with agentic frameworks (LangChain, LlamaIndex, or custom implementations)

• Strong backend skills: Python or Node.js, REST/GraphQL APIs, database design

• Structured thinking when working with unstructured documents and complex data formats

Nice to have:

• Familiarity with German tax or accounting context (DATEV, chart of accounts, P&L structure)

• Experience with document parsing (PDFs, OCR, table extraction)

• Comfort building in early-stage product environments

WHAT WE OFFER

• The opportunity to shape the future of AI-driven software development at one of Europe's leading software companies.

• An internationally diverse and dynamic team of friendly, skilled colleagues who embrace autonomy.

• A fast-paced environment where you collaborate with top talent and share knowledge at every level.

• We believe great results require a healthy work-life balance, trust, and supportive coaching.
