WHO WE ARE Notion is the collaborative AI workspace where teams and agents think together https://www.youtube.com/watch?v=vkpYpWfEK5s. We're building one place where your knowledge, projects, meetings, and AI tools live side by side, so work is faster, clearer, and less fragmented. Millions of individuals, small teams, and large companies run their work on Notion. Notinos (our employees) are customer zero in bringing this future of work to life. We care about craft, building things that last, and the belief that great work is still fundamentally human. Our goal isn’t to ship the next feature. Each and every team of Notinos is working to set the standard for how humans work together in the AI era. From building a business’s system of record to making and managing AI agents to automating away the busy work, we care deeply about giving our customers more time for their life’s work. ABOUT THE ROLE: Millions of people use Notion — and this number is increasing every day. That means millions of people trust us to deliver a fast, reliable, and secure experience, and we value this more than anything. We want to keep earning trust, while also continuing to amaze our users with the tools they can build in Notion. The Data Product Platform team is responsible for designing, implementing, scaling and operating systems, tools and frameworks to build event-based or data powered product experiences. You’ll join a team of talented engineers in our mission to build the best in class foundational platforms that are key to the company’s business and product. Notion’s platforms and infrastructure are vital to enabling our product features like search, automations, user notifications, workspace analytics and Notion AI. WHAT YOU'LL ACHIEVE: - You'll own and play a pivotal role in the development of systems, tools and infrastructure that enable data and data systems powered product use-cases. - You'll work cross-functionally with engineers and partners from the Product, Data Science, Data Engineering and AI teams to deliver short- and long-term impact. - You’ll work on all levels of the stack including infrastructure, libraries and product code as needed to successfully build and deliver internal platforms that provide high leverage to multiple product teams - You'll be responsible for monitoring and operating systems in production. You’ll understand systems deeply, optimize performance and evolve critical production systems with minimal user disruption. SKILLS YOU'LL NEED TO BRING: - Curiosity in working across the stack: You enjoy understanding systems end-to-end—from product surfaces to infrastructure and data flows—and improving them with a hands-on, learn-by-doing mindset. - Data-driven approach to building & improving systems: You use metrics, traces, logs, and experiments to diagnose issues, validate hypotheses, and prioritize the fixes that deliver the most impact. - A knack for ergonomic developer & agentic tooling: You build interfaces that are intuitive and hard to misuse—thoughtful APIs, clear docs, and extensible patterns that help other engineers move faster. - Pragmatic and business-oriented: You care about the business impact of what you're building, and you prioritize projects accordingly. You're not just going after cool stuff—you understand the balance between craft, speed, and the bottom line. - Team player: You understand work is better, together. You enjoy collaborating cross-functionally to accomplish shared goals, and you care about learning, growing, and helping others to do the same. NICE TO HAVES: - You’ve had past experience working full-stack in Typescript and node.js ecosystem - You have worked on data or infrastructure-focused engineering teams, particularly ones that own a wide swath of software platforms (hosted or built in-house). You've experienced the challenges of scaling and re-architecting event-based platforms and infrastructure through orders of magnitude of growth and scaling data volume. Notion is committed
