About the Role

The Virtual Assistant team is redefining how N26 customers interact with their bank, investing in Generative AI to rethink the banking ecosystem. This role is for a Mid-Level AI Engineer focused on building the next generation of intelligent, multi-channel experiences, bridging complex banking needs with human-like automation using LLMs, RAG, and autonomous agents. The core mission is fast, reliable delivery of AI/ML models and intelligent agents into product infrastructure, with a focus on scalability, observability, and speed.

Responsibilities

  • Drive Fast Time-to-Market (TTM) by collaborating with stakeholders to iterate quickly on prototypes and transition validated models into production.
  • Productionize AI/LLM Prototypes by refactoring, deploying, and maintaining robust AI services in a high-traffic production environment.
  • Build Observability and Measurement Systems by implementing comprehensive solutions for deployed AI features and measuring output quality.
  • Architect for Reliability and Scale by designing and implementing technical architecture, data pipelines, and orchestration systems for AI services.
  • Design and Deploy Custom AI Services by leveraging foundational models and building surrounding application logic and custom components.
  • Apply Advanced AI Techniques such as Retrieval-Augmented Generation (RAG), Model Context Protocol (MCP), Agent-to-Agent (A2A) flows, and fine-tuning.
  • Contribute to Discovery by identifying and recommending new AI use cases based on system constraints and production feasibility.

Requirements

  • Proven experience building, deploying, and maintaining machine learning or LLM-based applications in a production environment.
  • Strong blend of experience across Backend Engineering (Python, Kotlin), Applied AI Engineering & MLOps (LLM frameworks, vector databases, MLOps tooling, prompt engineering, RAG), and Data Engineering (data pipelines, feature stores, data quality).
  • Solid understanding and practical knowledge of cloud environments (AWS) and deploying scalable containerized services (Kubernetes, Docker).
  • Experience with model/LLM serving platforms (e.g., SageMaker, Bedrock, Vertex AI) is highly desirable.
  • A passion for moving fast and achieving tangible business outcomes.
  • A passion for knowledge transfer and feedback within a collaborative team.
