Sr AI Engineer (Fullstack - TS/Vue/NodeJS)

New Today

Overview

n8n is a workflow automation platform that combines AI capabilities with business process automation. We enable technical teams to move fast with a code-friendly yet no-code approach, backed by a community of builders. With 500+ integrations and fair-code principles, we are changing how businesses connect systems and processes.

We were founded in 2019 and currently:

  • We’re a diverse team of +140 people

  • Annual recurring revenue is growing over 9x year over year

  • With +130k GitHub stars, we are among the top 50 most popular projects of all time on GitHub

  • We were the 25th fastest growing startup last year and 4th in Europe for BtoB SaaS Rising 100 this year, per Sifted

  • We were Sequoia's first seed investment in Germany, and recently secured a $60M Series B (February 2025, led by Highland)

As a Senior AI Engineer, you will drive intelligent features that redefine how users build automations. You will build AI-powered capabilities, from natural language input to smart suggestions, to make creating workflows faster and more intuitive.

You will collaborate across engineering, product, and design to bring generative AI and LLM-based enhancements into the core user experience. You will improve existing AI integrations, develop new ones, and shape how AI powers our product.

You’ll work across the entire AI feature lifecycle.

Responsibilities

  • Architect and implement AI-powered capabilities: code generation, intelligent node creation, and workflow optimization

  • Integrate LLM APIs and embedding models for text-to-workflow and natural language code suggestions

  • Design and iterate on prompts to improve model output and user experience

  • Build internal tooling, evaluation benchmarks, and automated testing for AI components

  • Collaborate closely with other engineers to ensure AI features are reliable, performant, and scalable

  • Balance experimentation with impact: ship quickly while focusing on user value

  • Stay current with advances in LLMs, prompt frameworks, and developer tools, and bring those insights into our roadmap

Requirements

  • 5+ years of experience building web-based products, ideally in B2B SaaS startups

  • Strong fullstack development skills with TypeScript, Node.js, and API design

  • Proven track record shipping AI-powered features in production with LLM APIs (OpenAI, Anthropic, etc.) and understanding of how to translate machine intelligence into user value. We are looking for experience building end-to-end systems.

  • Deep understanding of AI fundamentals: agent architectures, chat completion roles, embedding vectors, vector databases, and chunking strategies

  • Hands-on experience with prompt engineering, embedding models, and vector stores

  • A user-focused mindset: you care about delivering features that solve real problems

  • A bias for shipping and learning — fast iteration is second nature to you

Bonus Points For

  • Experience fine-tuning LLMs or working with retrieval-augmented generation (RAG) systems

  • Frontend experience using Vue or React

  • Technical writing or documentation contributions, especially around developer tools or AI

  • Experience with agent orchestration patterns and state management in multi-step AI systems

  • Knowledge of code quality evaluation metrics and context optimization techniques
