Agentic AI Engineer (m/f/d)

Join our Data Science team and help shape SIXT's Customer Service Transformation. You will work on the AI assistant CARA, a production multi-agent system that authenticates customers, manages reservations, and handles policy questions across 10+ markets and 7 languages.

• You own agents end to end: prompt, orchestration graph, tools, evals, deployment, dashboard
• You write the agent logic and watch your own traces in production
• You translate business problems into agent capabilities, working with product, business and customer service stakeholders to define tool calls and sub-agents
• you build for real transactions with step-up authentication, guardrails, idempotent case handling, and handover into Salesforce and Genesys
• You make quality measurable, extending our evaluation harness with LLM-as-judge rubrics, tool-trajectory assertions and prompt A/B suites that gate every release
• You engineer for cost and latency as much as accuracy: multi-provider model routing with fallbacks, prompt caching, small models where small models win
• You collaborate across the stack with software engineers, data scientists, MLOps and platform teams, balancing bespoke agent logic against reusable platform capability
• you raise the floor around you by sharing agentic and LLM engineering knowledge with colleagues and helping other teams integrate Agentic AI into their products

• Engineering foundation You're an engineer first with strong, hands-on software engineering, real production ownership, excellent Python skills, and solid AWS cloud experience
• Agentic experience You have built tool-calling agents with LangGraph/LangChain or equivalent frameworks and shipped them to actual users rather than keeping them in notebooks
• Model and prompt expertise You're hands-on with frontier and open models like Anthropic Claude, OpenAI, AWS Bedrock, and open-source models such as Llama
• you treat prompt engineering as an engineering discipline: versioned, reviewed, evaluated, A/B tested
• LLMOps paradigm You know and have applied LLMOps: tracing, evals, guardrails, token and latency budgets, continuous integration and deployment
• Motivation and communication You're extremely motivated, passionate about learning, bring a genuine can-do attitude, communicate fluently in English, and appreciate cultural diversity
