Job Zusammenfassung
In diesem Job entwirfst und implementierst du autonome KI-Agenten, optimierst RAG-Pipelines und entwickelst APIs, um intelligente Systeme zu schaffen, die eigenständig Entscheidungen treffen und sich weiterentwickeln.
Job Technologien
Deine Rolle im Team
- We are on a lookout for a hands-on Senior AI Scientist (Agentic AI) to join the Vendor Data Team on our journey to always deliver amazing experiences to go beyond prompt engineering into autonomous orchestration: designing agents that generate their own prompts, tools that empower AI with real-world actions, and judge models that validate outputs.
- Your work won't sit in research notebooks - it'll ship.
- The Agentic AI team is building the next generation of AI-native products - intelligent systems that reason, act, and adapt.
- We combine the power of large language models (LLMs), autonomous agents, and retrieval-augmented generation (RAG) to move beyond static prompts and chatbots into dynamic AI systems that solve real problems at scale.
- We don't treat LLMs as tools to micromanage - we treat them as collaborators.
- Our products are designed to build and evolve themselves, leveraging AI to orchestrate workflows, make decisions, and continuously improve.
- Architect and deploy agent-based systems using LangGraph, PydanticAI, LangChain, Google ADK, Claude SDK, or custom-built orchestration frameworks.
- Build and optimize RAG pipelines - from smart chunking to embedding strategies and vector search.
- Design self-evolving prompt systems and dynamic decision flows driven by LLMs.
- Develop APIs and services that let models talk to tools, data, and other systems.
- Monitor, evaluate, and automate model feedback loops using AI-based simulation and testing agents.
- Work cross-functionally with product and engineering teams to ship AI-native features, not just prototypes.
Unsere Erwartungen an dich
Qualifikationen
- Deep knowledge of RAG, LLM mechanics, prompt design, and chaining.
- You take ownership. If something is unclear or blocked, you figure it out or find a way around it.
- You move fast but don't cut corners - you care about quality and impact.
- You believe working code beats perfect plans, and that iteration is the fastest way to clarity.
- Judge models, feedback loops, or human-in-the-loop architecture.
- Familiarity with prompt injection mitigation, output validation, or agent safety.
- Background in shipping AI inside real-world web or mobile products.
Erfahrung
- 2+ years of experience in applied AI/ML engineering with real-world deployments.
- Strong Python skills and experience with frameworks like LangChain, LlamaIndex, or Haystack.
- Experience with vector databases (Pinecone, Weaviate, FAISS) and embedding models.
- Nice to have: Open-source model experience (e.g., LLaMA2, Mixtral, Mistral) or custom inference stacks.
- Experience designing test harnesses using agent personas or synthetic users.
Unser Angebot
- Ensuring you and all our Heroes are looked after, happy, and healthy is always on the menu.
- Make the most of our hybrid working model and join the team for face-to-face connection and collaboration in our beautiful Berlin campus 2 days a week.
- We offer 27 days holiday with an extra day on 2nd and 3rd year of service.
- We will support you in developing yourself and your career growth opportunities: 1.000 € Educational Budget, Language Courses, Parental Support and access to the Udemy Business platform to explore a variety of online courses.
- Get moving and release those wonderful, mind-boosting endorphins: Health Checkups, Meditation, Yoga, Gym & Bicycle Subsidy.
- Cash. Dough. Cheddar. Whatever you call it, we'll help you with it: Employee Share Purchase Plan, Sabbatical Bank, Public Transportation Ticket Discount, Life & Accident Insurance, Corporate Pension Plan.
- The power of getting together over some food is unrivaled. Here are a few ways to help you do that. All the yum: Digital Meal Vouchers, Food Vouchers, Corporate Discounts.
