Role 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.

We’re in a defining moment of an incredible journey. Come and build with us.

Missions
As a Senior Engineer in our Growth team, you’ll ideate, build and iterate on the product experiences that turn users into successful, long-term customers. You’ll own high-impact parts of the Cloud journey — from signup and onboarding to billing, upgrade flows, and in-product experience — using experimentation, product intuition, and data to improve activation, retention, and monetization.

This is a hands-on engineering role on a high-leverage growth team, working closely with product, design, data, marketing, and engineering to accelerate n8n’s self-serve growth engine.

What You’ll Do
🚀 Ship high-impact experiments – You’ll design, build, and A/B test new features to increase conversion and retention — think upgrade flows, contextual prompts, or new pricing nudges

📈 Drive measurable business outcomes - Your work will directly contribute to n8n’s ARR, user retention, and growth KPIs. You'll track performance, identify areas to improve, and ship iteratively to increase activation and retention

🧠 Scale our growth systems – You’ll help build and optimize services to enable user growth at scale, like in-app messaging platforms, billing systems, and email orchestration tools

🔧 Improve and maintain growth-critical features – You’ll take ownership of flows like signup, onboarding, and the admin dashboard to ensure a smooth, performant experience for every new user

Projects You Might Tackle
Personalizing onboarding based on initial interactions to get more users to first success

Testing AI credit metering and the UI around it: usage limits, paywalls, and upgrade nudges

Building experimentation infrastructure

Requirements
🧑‍💻 5+ years of full-stack engineering experience with TypeScript/JavaScript, Node.js, and Vue or React (plus HTML/CSS/UI libraries).

📈 You've owned growth metrics: product activation, retention, or revenue, on a growth or PLG team at a SaaS company

🧪 You've shipped experiments yourself, from hypothesis to ship/kill decision

🧠 Product mindedness: You can ship without a PM and make the right call most of the time. You can talk to users when you need the signal.

📊 Data fluency: You can query data yourself and make decisions from user behaviour and experiments

🧭 Comfort with ambiguity: You don't wait for perfect specs or designs. You move forward and iterate.

⚡ Speed + ownership mindset: You move fast but responsibly, understanding that experimentation and velocity are core to unlocking growth.

Nice-to-have
💸 Exposure to pricing strategy, funnel optimization, or revenue KPIs

🏁 Past experience as a founder or early-stage startup engineer
