Job Summary
In this role, you'll develop custom, production-ready AI solutions and work on our own AI product, focusing on architecture, evaluation, and handling complex data processing.
Job Technologies
Your role in the team
- Onefold AI is a Vienna-based AI consultancy and product company. We build custom, production-grade agentic AI systems for our clients - and we're developing our own AI product in parallel. We're a small, senior and experienced team with no layers, no handoffs, and no meetings that could have been messages. If you build it, you ship it, and you stand behind it.
- We're growing - both our client work and our product ambitions. This role splits roughly between consulting engagements and product development, with a structure that protects time for both. You won't be constantly context-switching: when you're on a client project, you're focused there; when you're on the product, that time is yours to build. As we grow, we plan to move toward dedicated product roles - and this position puts you in a strong place to shape that transition.
- On the consulting side, you'll work directly with clients to design and deliver AI solutions. This means understanding their problems, scoping what's feasible, and building systems that hold up in production.
- 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.

Our expectations of you
Qualifications
- You are curious and intrinsically motivated to create outstanding, AI-based solutions together as a team.
- 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.
- 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.
- Vertrautheit mit Bewertungsrahmen: benutzerdefinierte Bewertungen, LLM-als-Richter, systematische Qualitätsmessung.
- German-speaking.
Experience
- 2+ Jahre Berufserfahrung in Softwareentwicklung oder AI/ML-Entwicklung in der Produktion.
- Solid experience with RAG systems and agentic architectures: you've built these, maintained them, and learned what breaks.
- Experience with document processing: OCR, PDF extraction, structured data from unstructured sources.
- Experience with any cloud platform (Azure, AWS, GCP) - we're not locked to one.

What we offer

- Participation in the company (equity shares / 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.
- Firmenlaptop und Mobiltelefon.
- 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.
