Our AI assistant CARA authenticates customers, manages real reservations, and handles policy questions across 10+ markets and 7 languages. She's a production multi-agent system with write access to SIXT's booking platform, running on chat, app, WhatsApp, and soon voice. Your work will impact millions of customers and deliver measurable business results.\nYOUR ROLE AT SIXT\nYou own agents end to end: prompt, orchestration graph, tools, evals, deployment, dashboard. You write the agent logic and watch your own traces in production\n\nYou translate business problems into agent capabilities, working with product, business and customer service stakeholders to define tool calls and sub-agents, and you build for real transactions with step-up authentication, guardrails, idempotent case handling, and handover into Salesforce and Genesys\n\nYou make quality measurable, extending our evaluation harness with LLM-as-judge rubrics, tool-trajectory assertions and prompt A/B suites that gate every release\n\nYou engineer for cost and latency as much as accuracy: multi-provider model routing with fallbacks, prompt caching, small models where small models win\n\nYou collaborate across the stack with software engineers, data scientists, MLOps and platform teams, balancing bespoke agent logic against reusable platform capability, and 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\n\nYou work with the following stack context: Python with LangGraph and LangChain, deployed as containerised agents on AWS Bedrock AgentCore with MCP sub-agents and OpenAPI tool federation. Multi-provider fallback chains with Anthropic and OpenAI LLMs behind Bedrock Guardrails. Next: CARA for Voice\n\nYOUR SKILLS MATTER\nEngineering foundation You're an engineer first with strong, hands-on software engineering, real production ownership, excellent Python skills, and solid AWS cloud experience\n\nAgentic 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\n\nModel 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, with a clear point of view on when to use which, and you treat prompt engineering as an engineering discipline: versioned, reviewed, evaluated, A/B tested\n\nLLMOps paradigm You know and have applied LLMOps: tracing, evals, guardrails, token and latency budgets, continuous integration and deployment\n\nBonus skills MCP, real-time voice AI (WebRTC, SIP, streaming STT/TTS), event-streaming pipelines, TypeScript/React, or contact-centre platforms like Genesys and Salesforce add value\n\nMotivation and communication You're extremely motivated, passionate about learning, bring a genuine can-do attitude, communicate fluently in English, and appreciate cultural diversity\n\nWHAT WE OFFER\nA Global Tech Hub in Lisbon Join a thriving international tech community and work alongside engineers, product experts, and business teams who turn ideas into real impact. Our hubs at Factory Lisboa in Beato and ARTs Lisboa in Parque das Nações are where great tech gets built\n\nLearning & Knowledge Exchange Level up through regular events with internal and external speakers.
