Software Engineer, Mail

About Us:

We're on a mission to make it possible for every person, team, and company to be able to tailor their software to solve any problem and take on any challenge. Computers may be our most powerful tools, but most of us can't build or modify the software we use on them every day. At Notion, we want to change this with focus, design, and craft.

We've been working on this together since 2016, and have customers like OpenAI, Toyota, Figma, Ramp, and thousands more on this journey with us. Today, we're growing fast and excited for new teammates to join us who are the best at what they do. We're passionate about building a company as diverse and creative as the millions of people Notion reaches worldwide.

Notion is an in person company, and currently requires its employees to come to the office for two Anchor Days (Mondays & Thursdays) and requests that employees spend the majority of their week in the office (including a third day).

About the Role:

Email isn’t going anywhere — but it can be a lot better. We're building Notion Mail to rethink how communication fits into the bigger picture of your work and life. As a Software Engineer on our team, you’ll help create an email experience that's fast, delightful, and seamlessly woven into everything people already love about Notion. You'll collaborate across engineering, product, and design to bring new ideas to life — and you’ll have tons of room to shape the foundations of a product still in its early days. If you get excited about big challenges, moving fast, and making everyday tools a little more magical, we’d love to work with you.

What You’ll Achieve:

• Design and build the Notion Mail backend, which includes multiple services for API routing, request processing, asynchronous workflows, and AI features


• Architect the foundation for a Notion email service, including email servers, email/spam reputation, and custom domain


• Implement Notion Mail AI features, such as labeling/classification, drafting, and Q&A


• Build a secure foundation for all Mail features, including authorization and authentication, OAuth signup flows across multiple email providers, and secure token and user data management


• Design and implement email delivery and routing systems, including message queueing and processing


• Develop spam detection and filtering mechanisms


• Establish monitoring, testing, & alerting observability systems

Skills You'll Need to Bring:

• Put users first: You think critically about the implications of what you're building, and how it shapes real people's lives. You understand that reach comes with responsibility for our impact—good and bad.


• Pragmatic and business-oriented: You care about business impact and prioritize projects accordingly. You're not just going after cool stuff—you understand the balance between craft, speed, and the bottom line.


• Not ideological about technology: To you, technologies and programming languages are about tradeoffs. You may be opinionated, but you're not ideological and can learn new technologies as you go.


• Empathetic communication: You communicate nuanced ideas clearly, whether you're explaining technical decisions in writing or brainstorming in real time. In disagreements, you engage thoughtfully with other perspectives and compromise when needed.


• Team player: For you, work isn't a solo endeavor. 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:

• Knowledge of identity and authentication - Oauth, SAML.


• Experience with email & domains infrastructure, such as email servers, IP reputation, and more.
