Sr AI Engineer | Remote - Europe | TS/Vue/NodeJS

The AI orchestration of your wildest imagination. n8n is the open workflow orchestration platform built for the new era of AI. We give technical teams the freedom of code with the speed of no-code, so they can automate faster, smarter, and without limits. Backed by a fiercely inventive community and 500+ builder-approved integrations, we’re changing the way people bring systems together and scale ideas for impact. Since our founding in 2019, we’ve grown into a diverse team of over 260 - working across Europe and the US, connected by a shared builder spirit and with our centre of gravity in Berlin. Along the way, we’ve: - Cultivated a community of more than 650,000 active developers and builders - Earned 190K+ GitHub stars, making us one of the world’s Top 40 most popular projects - Backed by top investors, from Sequoia’s first German seed to our SAP's recent strategic investment - bringing us to a $5.2bn valuation That’s the company we’ve built. Now we’d love to see what you can build. If you’re applying, try n8n out - whether you’re technical or not - and share a screenshot of your first workflow with us.

As a Senior AI Engineer, you'll drive intelligent features that redefine how users build automations. You'll build AI-powered capabilities, from natural language input to smart suggestions, that make creating workflows faster and more intuitive. You'll collaborate across engineering, product, and design to bring generative AI and LLM-based enhancements into the core user experience. You'll improve existing AI integrations, develop new ones, and shape how AI powers our product. You’ll work across the entire AI feature lifecycle: - 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 - Experience shipping AI-powered features in production with LLM APIs (OpenAI, Anthropic, etc.) and understanding of how to translate machine intelligence into user value. We're looking for experience building end-to-end systems. - 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 n8n is an equal opportunity employer and does not discriminate on the basis of race, religion, colour, national origin, gender, sexual orientation, gender identity, age, marital status, veteran status, or disability status.
