## About the Role

* You are curious and intrinsically motivated to create outstanding, AI-based solutions together as a team
 * 2+ years of professional experience in software engineering or AI/ML development in production
 * Solid experience with RAG systems and agentic architectures: you've built these, maintained them, and learned what breaks
 * Strong Python and general software architecture skills, TypeScript is a bonus
 * The ability to work independently in ambiguous situations - we're a small team and you won't always have a spec
 * Comfort being client-facing: you can explain technical decisions to non-technical stakeholders without dumbing things down
 * A learning pace that matches how fast this field moves - what you learned six months ago might not be enough anymore, * Experience with document processing: OCR, PDF extraction, structured data from unstructured sources
 * Cost-conscious engineering: token budgets, caching, model routing, knowing when a smaller model is the right call
 * Background in consulting or agency environments where you've juggled multiple projects and clients
 * Familiarity with evaluation frameworks: custom evals, LLM-as-judge, systematic quality measurement
 * Experience with any cloud platform (Azure, AWS, GCP) - we're not locked to one
 * German-speaking

## Description

On the product side, you'll contribute to our own AI product from early stage through to production. You'll have real influence over architecture, features, and direction - the kind of input that only exists in a team this size., * Design and build agentic workflows - orchestration, tool use, function calling, multi-step reasoning

 * Build and improve RAG pipelines end to end: chunking strategies, embeddings, retrieval, re-ranking
 * Own quality: set up evaluation pipelines, measure what you ship, iterate based on data instead of intuition
 * Debug across the full stack when things break in production
 * Work with messy, real-world data: PDFs, scanned documents, unstructured enterprise content, * A seat at the table - in a team of this size, your input shapes the product and the company direction
 * Variety: client projects keep things fresh, product work gives you long-term ownership
 * Real autonomy paired with real accountability
 * Participation in the company (Unternehmenswertanteile / UWAs) - we want you invested in what we're building, literally
 * Learning budget for conferences, courses, and staying current in a field that moves weekly
 * Company laptop and mobile phone
 * Vienna-based with real remote flexibility - no performative office time
 * Salary based on the Austrian IT collective agreement (KV), with compensation adjusted to your experience and skills
