AI Engineer (m/f/d) for Chat-to-CAD / CAD-Automation

Welcome to CADAICO, the home for curious developers, AI nerds, geeks and engineering talents, with a focus on CAD design.

# Only applications accompanied by a covering letter will be considered. #

A large part of our work involves taking a wide variety of inputs – text, drawings, technical documentation – and extracting as much information as possible from them, feeding it into a CAD design pipeline. Tell us in two or three sentences where you’ve built something like this before: What were the challenges involved, and how did you solve them?

Our dev team is small but excellent – just two or three people. Your work is immediately visible and makes a difference from day one. If you’re looking for real responsibility, this is the place for you.

Our start-up

CADAICO, the ‘Chat-to-Design’ company, is a start-up based in Stuttgart founded by Pedram, a former mid-level manager in mechanical engineering, and Daniel, an AI researcher from KIT.

Our team builds software that combines AI methods with conventional algorithms – enabling mechanical engineers to create their ** designs automatically **, rather than manually using CAD tools.

With promising projects in the pipeline, we have a solid foundation for the next phase of growth and are looking for people who ** think independently, take responsibility and want to build real AI products** that will shape the field of mechanical engineering.

Aufgaben

What you’ll be doing with us

• Gradually develop the AI core of our Chat-to-Design product: from the LLM integration right through to the ** production-ready CAD pipeline**
• Ensure that our software learns from customers’ specific needs – via versioned system prompts, knowledge bases, rule sets, feedback and memory systems. Achieve customer-specific customisation through architecture rather than weighting
• Teach our product to reliably extract all the necessary information from a small number of very different inputs – including non-textual ones – ** and feed it into a CAD pipeline **, complete with the necessary retrieval and knowledge modules for design and component data
• Create Agentic Workflows: tool use, function calling, multi-stage reasoning and robust error handling
• Implement complex AI ideas as reliable, productive software features – in collaboration with our engineers.

Qualifikation

What you should bring to the role

• Experience in using AI methods to solve problems in CAD design (2D/3D)
• Experience in turning unstructured or ambiguous inputs into structured, reliable results – ideally also from non-textual sources (images, documents, technical documentation)
• Excellent knowledge of Python and clean, maintainable engineering – coding, testing, comprehensible APIs
• Experience with retrieval (embeddings, vector search, re-ranking) – and an understanding of why this is more challenging with real-world data than in tutorials
• Experience with **Agentic Workflows **: tool usage and function calling, multi-stage reasoning – and an understanding of what happens when the model gets it wrong
• **A desire to delve deeply into a subject **, make your own decisions and quickly get to grips with unfamiliar topics
• Very good English and good German language skills for confident internal and external communication
• An **existing work permit for Germany **. As a small team, we’re unfortunately unable to provide visa support.

It’d be great if you know a bit about these – you’ll learn the rest with us.

• Agent frameworks such as LangGraph, LlamaIndex, Pydantic AI or MCP
• Systematic evaluation of LLM outputs (Golden Sets, LLM-as-Judge, Langfuse, Ragas)
• Experience with extracting information from images or documents
• CAD software or experience in the ** mechanical engineering** field

Benefits

What we offer

• Based in Stuttgart (on-site) with ** highly flexible working hours** and ** hybrid working**
• Agile working with flat hierarchies: No endless approval loops. You’ll take responsibility, make decisions and implement them quickly
• Strong development opportunities: Your opportunities grow alongside our start-up
• Genuine responsibility and a visible impact: What you do matters. A great deal, in fact.
• Room to experiment: Develop ideas, test them quickly, learn and put them into practice
• Salary: €60,000 – €85,000 + VSOP options depending on experience and level of responsibility.

Why CADAICO?

If you want to take on responsibility and ** enjoy going to work **, you’ve come to the right place ;)

We welcome applications from people of all backgrounds, age groups and identities.

Send your CV along with your answer to the question above ** in a short cover letter** and, if you like, a ** link to something you’ve built** (repo, demo, blog post)

We look forward to getting to know you.
