Software Engineer (AI + Python) (f/m)

Your responsibilities

About the RoleJoin our team of AI pioneers at Home Connect on their quest to make our next-generation IoT platform even smarter.As an AI Engineer, you will be responsible for developing and operating LLM-based AI systems written in Python - from simple RAG to complex Agent solutions.Your will focus on productionizing AI applications at scale, starting with the personalization and enhancement of the connected cooking experience.

What You’ll Do:

• Architect AI Systems: Design, develop, and deploy production-ready GenAI and Agent Solutions using orchestration frameworks like LangGraph to automate complex user interactions and challenging workflows.

• Optimize AI Performance: Evaluate, measure and improve our AI solutions across all dimensions: quality, speed, cost and quotas.

  • LLM Interactions: Master Prompt and Context Engineering to precisely govern LLM reasoning, behavior, and final output quality. This work directly ensures the system's reliability, safety, and efficiency, while minimizing operating cost and latency under production load.

  • Information Retrieval: Engineer advanced retrieval systems, utilizing various search techniques such as full-text search, vector search, and hybrid search on search engines like Elasticsearch to feed the AI the most relevant data for highly accurate, context-aware, and timely responses.

• Ensure AI Observability: Integrate and utilize AI application monitoring tools, particularly Langfuse, to observe, trace, evaluate, and continuously improve agent performance and RAG quality.

• Ensure Platform Stability: Apply load balancing and scaling techniques to handle real-world load across LLM deployments and computational resources.

• Code Quality & Ownership: Write clean, production-ready, scalable, and well-tested code in Python, including testing the AI logic end-to-end.

• Collaborate & Lead: Work closely with product managers and cross-functional engineering teams to guide technical decisions and translate abstract AI concepts into deployed, impactful features.
