Senior AI Engineer (f/m/d)

About this role

Responsibilities

• You join our Engineering team as a senior individual contributor and report directly to the CTO. We work in small, cross-functional product teams without middle management; you own your projects end to end, from design to production operation. Your mission: Enable fully-automated supplier analysis at stellar quality.
• Your responsibilities
• Design, build and operate production AI agents with LangGraph, including agentic workflow patterns (planning, tool use, reflection, human-in-the-loop)
• Build NLP and RAG pipelines (vector databases, retrieval strategies, evaluation) that feed the agents
• Integrate agents reliably with our backend services (Python, FastAPI, Pub/Sub, GCP) and keep agent-to-agent and agent-to-backend interfaces scalable
• Own MLOps for agentic workloads: CI/CD, monitoring, evaluation pipelines, cost control and inference efficiency
• Set and meet quality targets (for example under 1% failure rate for the search agent) and benchmark models and approaches
• Keep the codebase healthy and share knowledge across the team through reviews and documentation

Requirements

• If you match most of these requirements and not all of them, you should still apply.
• At least 5 years of professional experience as an AI, ML, MLOps or backend engineer (working-student time does not count)
• Hands-on experience shipping LLM-based or agentic systems to production, not only prototypes
• Degree in computer science, AI or a closely related field, or equival
