Job Description
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. The easiest place to start is here: app.n8n.cloud/register http://app.n8n.cloud/register.
We’re in a defining moment of an incredible journey. Come and build with us.
🎯 Your main goal will be to build and evolve core platform foundations that power n8n’s workflow engine and frontend platform, enabling product engineers (and the open-source community) to ship confidently across cloud and self-hosted deployments.
As part of the team, you'll contribute to core platform domains and help improve reliability, scalability, and performance:
BACKEND PLATFORM FOUNDATIONS (EXECUTION, ORCHESTRATION, DATA)
- Contribute to backend subsystems like durable workflow execution & state, orchestration patterns, queue/task distribution, and system modularization.
- Apply best practices for correctness and resilience (e.g., failure modes, idempotency, state handling) in systems that operate across cloud and self-hosted environments.
- Improve data architecture and database performance, reliability, and maintainability.
FRONTEND PLATFORM FOUNDATIONS (CANVAS, COLLABORATION, PERFORMANCE)
- Work on the core canvas architecture and frontend platform primitives that enable complex workflow building experiences.
- Build and improve real-time collaboration capabilities (e.g., WebSockets, CRDT-style approaches) with a focus on correctness and user experience.
- Contribute to performance and rendering improvements (e.g., web workers, rendering optimization), and help strengthen platform contracts (plugin system, FE DX).
TECHNICAL CONTRIBUTION & COLLABORATION
- Contribute to technical decisions through clear proposals (e.g., RFCs) and discussions.
- Collaborate with other teams to ensure platform changes integrate smoothly.
- Support peers through code reviews, pairing, and knowledge sharing.
REQUIREMENTS
MUST-HAVES
- 🧠 Systems thinking mindset: You think about correctness, trade-offs, and reliability — and enjoy working on foundational platform problems.
- 🏗️ System design experience: You’ve contributed to system design decisions or worked on significant components, and can explain your technical choices clearly.
- 🛠️ TypeScript depth: You have strong TypeScript experience and you’re comfortable working in a large, evolving codebase.
- 🤝 Collaboration: You communicate well, work cross-functionally, and collaborate effectively with other engineers.
- 🧹 Pragmatic engineering: You’re comfortable improving and refactoring existing systems to make them more scalable and maintainable.
FOR BACKEND-FOCUSED CANDIDATES:
- 🧩 Node.js backend systems: You’ve built backend systems in TypeScript/Node.js beyond CRUD.
- 🌐 Distributed systems: You understand event-driven patterns, idempotency, and reliability in distributed environments.
- 🗄️ Data architecture: You’ve worked on data-intensive services, including performance and operational considerations.
FOR FRONTEND-FOCUSED CANDIDATES:
- 🧱 Complex frontend systems: You’ve built architecture-heavy frontend products (e.g., canvas, real-time, collaborative, or similarly complex apps).
- ⚡ Performance expertise: You have experience with rendering performance optimization and can measure and improve runtime behavior.
- 🖥️ Modern frontend TypeScript: You’re strong in TypeScript frontend development; Vue experience is preferred but not required.
NICE-TO-HAVES
- 🧰 Workflow/orchestration or devtools experience: You’ve worked on workflow engines, orchestration platforms, developer tools, or infrastructure-adjacent SaaS.
- 🌍 Open-source experience: You’ve contributed to or maintained OSS, and understand public API contracts and backward compatibility.
- 📈 Large-scale SaaS exposure: You’ve worked on systems with meaningful scale or complexity.
- 🧩 Monolith → modular migrations: You’ve contributed to decomposing monoliths or evolving systems toward modular architectures.
- 🧾 Durable execution patterns: Familiarity with event-driven or workflow execution patterns (e.g., queues, retries, sagas).
- 🧑🤝🧑 Collaboration tech (FE): Experience with collaborative or real-time applications.
- 🧵 Frontend platform patterns (FE): Experience with plugin systems, micro-frontends, or web workers.
- ☁️ Multi-deployment awareness: Exposure to both cloud and self-hosted environments.
- 🔭 Observability mindset: You care about operability (instrumentation, debugging, rollout safety).
WHY JOIN US?
At n8n, you’ll work on the foundations that everything else depends on — the execution engine and platform primitives that power a widely-used open-source automation product across cloud and self-hosted deployments. You’ll tackle greenfield-meets-evolution problems (modularizing a monolith while building new primitives), and see your impact through both produ…
