Ready to Build the First AI Layer of a Global SaaS Product?

We're hiring our first AI Engineers to help turn years of data, insights, and pricing expertise into intelligent automation. Your mission: build the AI foundation of our platform and bring our AI Pricing Copilot to life - used by some of the world's biggest retail and e-commerce brands in over 30 countries.

You'll work across LLM tools, retrieval pipelines, and backend APIs to create real product features - with the freedom to define the stack, best practices, and long-term architecture.

Your Mission - Build AI Capabilities That Power Real-World Decisions

  • Design and implement LLM-driven features, from retrieval-augmented generation (RAG) to summarization and insights
  • Build and maintain Python APIs (FastAPI) to serve AI features in production
  • Integrate with vector databases, model endpoints, and internal pricing data
  • Prototype with frameworks like LangChain, LangGraph, or CrewAI — then turn experiments into stable features
  • Shape our AI roadmap and tooling decisions as our founding AI engineer
  • Collaborate with backend and data teams to bring models to production and ensure reliability

 Skills, and experience to unlock the role:

  • Solid experience with LLM applications, RAG, or multi-agent flows using LangChain, CrewAI, or equivalents
  • Strong Python development skills, especially in data-heavy environments
  • Familiarity with model APIs (OpenAI, HuggingFace) or custom model deployment
  • Experience with vector databases (e.g. FAISS, Weaviate, Qdrant)
  • Comfortable working with APIs, structured data (SQL), and version control
  • A product-minded builder — you care about delivering real, usable outcomes
  • Clear communication skills in async, remote-friendly teams

 Bonus Points For:

  • Experience bringing AI features into production SaaS products
  • Comfort with MySQL, Redis, or document-based stores
  • Familiarity with observability and monitoring for data/AI pipelines
  • Some Exposure to Elixir or interest in integrating with non-Python services
  • Background in pricing, retail, or e-commerce data environments

What You Get - Perks That Matter

  • Private health insurance
  • 25 days paid leave, plus your birthday off
  • Monthly lunch allowance & free coffee/snacks
  • Hybrid work: flexible WFH schedule + 2 team days onsite
  • Support for courses, degrees, and tech seminars
  • Modern office & casual team lunches
  • Social events, game nights, and team offsites
