About this role

Welcome to Arbio – where AI meets hospitality, and every day is a step toward redefining short-term rentals across Europe.

Arbio is a fast-growing, AI-enabled hospitality company. We are redefining the short-term rental industry through technology-driven efficiency, exceptional guest experience, and scalable operations. As a team, we're shaping the future of hospitality with cutting-edge AI solutions, expanding rapidly across Europe, and building on a culture of performance and accountability. Join us as we lead the industry and create opportunities for growth, innovation, and success.


What you will add to our Crew:

  • Strong TypeScript skills
  • Proven experience building RAG systems end-to-end
  • Deep knowledge of LangChain and agent architectures
  • Expertise in MongoDB vector search
  • Comfort working with multiple LLM APIs

Bonus Points:
  • Prompt engineering, fine-tuning, or chunking strategies
  • Debugging production AI systems and familiarity with evals techniques
  • Background in hospitality or enterprise knowledge management

Why you will love this
  • Work with cutting edge technology 
  • Build something some scratch, with direct impact on product direction
  • Competitive salary and a cool Berlin office
  • Be among other builders, with an AI-first mindset.

As an Senior AI Engineer, you’ll build the intelligence layer that powers our operations—from property management to guest services. We’re developing cutting-edge Retrieval-Augmented Generation (RAG) systems that transform scattered data into instant, actionable insights, enabling our teams to deliver world-class guest experiences.

You will have an impact on:
  • Designing high-performance RAG pipelines using MongoDB Vector DB for lightning-fast semantic search
  • Building LangChain-based agent workflows for complex reasoning tasks
  • Integrating multiple LLM providers (Claude, OpenAI, Gemini)
  • Writing clean, scalable TypeScript code to support rapid growth
  • Monitoring & optimizing with LangSmith and other LLMOps tools
  • Collaborating with a small, agile team to push the boundaries of AI in hospitality

Our current benefits

  • Real impact, not AI theater. Airbnb & Booking hand you soulless AI replies - build the better ones.
  • Unlimited token budget, seriously. Opus 4.6, GPT 5.4, Gemini 3.1 Pro - whatever makes you more productive, you get.
  • A culture that ships, not debates: short, direct decisions instead of endless meetings. Plus a competitive salary, benchmarked against the market.
  • Modern, centrally located office in Berlin. 25 days of paid vacation, Urban Sports or Wellpass, access to the Nilo mental health platform.
  • Fully taken care of: lunch & dinner 3x/week, breakfast daily, snacks, coffee & matcha always stocked.
  • Office Yoga, run club, team events - plus free stays at our apartments across Europe.

What joining the Arbio Squad means for you

We are dedicated to nurturing and pushing each of our team members to unleash the best version of their professional selves. We believe in a culture of trusted ownership, caring meritocracy, and constructive feedback where we elevate each other while constantly challenging the status quo. Join a dynamic, young company with an entrepreneurial culture operating at lightning speed — with eyes set on global horizons!
