Senior AI Engineer (LLM/RAG Systems)

We're looking for an experienced AI Engineer to join our fully remote team. If you've built production AI systems with LLMs, know your way around RAG architectures, and want to work on a product where AI is the core — not an afterthought — this role is for you.

What You'll Do

• Design and build LLM-powered features and AI agent pipelines — from prompt to production
• Extend and optimize our RAG / knowledge base system: chunking strategies, embedding models, vector search, hybrid retrieval (BM25 + semantic), and reranking
• Implement agentic workflows with tool use, multi-step reasoning and structured outputs
• Build document- and email-processing pipelines that leverage LLMs for classification, extraction and summarization
• Integrate and manage LLM providers (OpenAI, Anthropic, etc.) and AI SDKs across the stack
• Design evaluation frameworks and feedback loops to measure and continuously improve AI output quality
• Build and optimize agents for our growing template library
• Operate in an AI-first development setup powered by Claude/Cursor
  
  
  

Our techstack

• Backend: TypeScript
• Frontend: Next.js, React, Tailwind, shadcn/ui
• AI: OpenAI & Anthropic APIs, Vercel AI SDK, vector search, semantic reranking
• Database: We don't want to disclose this publicly at the moment

• Deep familiarity with RAG architectures: chunking, embedding models, vector search, hybrid retrieval and reranking
• Experience with AI SDKs and frameworks (Vercel AI SDK, LangChain, LlamaIndex, or similar)
• Proficiency in TypeScript
• Comfort with agentic systems: tool use, structured outputs and evaluation
• You actively think about cost, latency and quality trade-offs and know how to optimize across all three
  
  
  

About Us

We are a German automation agency turned into a SaaS with our product hausverwalter.ai.

Most Germany property managers work with 5-10 software tools daily. Our goal is to replace them all, while also building autonomous agents right into the software.

The role is fully remote – though you're always welcome to drop by our office in Worms, Germany. You'll fit in well if you're after more than just the "freedom part" of remote work and are truly eager to roll up your sleeves and grow alongside us for the long haul.

Salary

$1000 - $3000 per month before taxes. There will be room for growth and promotion in the years ahead
