Software Engineer AI Platform

Notion is the collaborative AI workspace where teams and agents think together. 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.

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 AI Platform team is responsible for building the shared foundations that let Notion ship AI products quickly and operate them safely at scale. You’ll join a team of talented engineers focused on making speed and quality compatible: reliability and availability through provider changes quality and correctness systems like evals and release gates observability that makes failures explainable and shared primitives for model integrations context management long-running actions and cost/performance tradeoffs. Notion’s AI platform is vital to helping product teams move faster with production-grade guardrails as models providers and AI capabilities rapidly evolve.

This role can be based in either San Francisco or New York City. We work from our offices on Mondays Tuesdays and Thursdays (our Anchor Days) because we do our best thinking and building together in person. We’re looking for someone who’s excited to work alongside the team during those days.

• You'll own and play a pivotal role in the prototyping development and scaling of systems and core AI platform primitives.

• You’ll partner closely with product teams to provide paved paths and production-ready guardrails that help new AI features ship faster with less duplicated work.

• You’ll work across infrastructure shared libraries APIs and product integration points to make AI platform capabilities easy to adopt and high-leverage across Notion.

• You’ll operate critical AI systems in production using observability and diagnostics to understand provider/model behavior debug failures improve latency and cost and evolve systems with minimal user disruption.

• You’ll help Notion safely adopt new models providers and AI capabilities through versioning controlled rollouts compatibility layers and clear quality/reliability gates.

• Passion for AI systems at scale: You’ve worked on LLM ML platform data or infrastructure teams that own critical shared systems. You understand the challenges of scaling reliability latency cost and quality as usage and model complexity grow. You care deeply about building platforms that are dependable efficient and easy for other engineers to use.

• Adaptable and curious: You like going deep on how systems behave in practice especially when models providers and product requirements are changing quickly. You’re eager to use AI tools to work smarter and are willing to move across backend infrastructure libraries and product code when that’s what the problem requires.

• Extreme ownership: You’re comfortable working across ambiguous problem spaces aligning stakeholders around a clear path forward and driving execution with accountability. You take ownership of platform outcomes including reliability quality adoption and operational follow-through beyond team boundaries.

• Thoughtful problem-solving: For you problem-solving starts with a clear and accurate understanding of the context. You can decompose ambiguous system behavior debug across layers and work toward clean pragmatic solutions by yourself or with teammates. You’re comfortable asking for help when you get stuck.

• Pragmatic and business-oriented: You understand that AI platform work is full of tradeoffs across quality latency cost reliability and speed of execution. You prioritize based on product and business impact balancing craft with urgency and operational simplicity.

• 2-4 years of experience as a Software Engineer

• Experience with applied AI product development (prompting evals model integrations or quality measurement).

• You've built out and scaled data processing pipelines at scale with Apache Spark or Ray.

• You’ve past experience working full-stack in Typscript and node.js ecosystem

• You have experience building MLOps and ML serving infrastructure.
