Summary

This role is ideal for a mid-level Security Engineer with at least 3 years of experience in product security or security architecture. You are more than a "breaker"; you are a builder who enjoys working directly with developers to bake security into the software development lifecycle. Because Notion is a high-growth startup, they are looking for someone who thrives in fast-paced environments and can translate complex threats into pragmatic business risks. The compensation is highly competitive ($165k - $200k base) for a mid-level position, and you'll join as an early member of the AppSec team, giving you significant influence over their security roadmap. While the role is primary hybrid in SF or NYC (Mon/Tue/Thu in-office), they have indicated a willingness to consider fully remote arrangements for the right candidate. **You might be a good fit if you...** * Have a track record of finding and fixing vulnerabilities (SAST/DAST) in complex web applications. * Can lead cross-functional projects that convince product teams to adopt "the secure path." * Enjoy building automated tools to eliminate entire classes of bugs rather than just patching them. * Are active in the security community via bug bounties, CTFs, or regional conferences.

# What You'll Achieve:

# Skills You'll Need to Bring:

Security Architecture expertise: You have at least 6+ years of experience working with product teams to design and/or build secure software.

Thoughtful problem-solving: For you, problem-solving starts with a clear and accurate understanding of the context. You can decompose tricky problems and work towards a clean solution, by yourself or with teammates. You're comfortable asking for help when you get stuck.

Impact-driven approach to technology: You use technology to drive measurable user and business outcomes, not as an end in itself. You stay current with tools like Cursor, Claude Code, and other AI-assisted development environments, and you’re pragmatic about choosing what delivers the most value.

Pragmatic and business-oriented: You care about business impact and prioritize projects accordingly. As a product security expert you communicate and facilitate understand of the threat model and risks with the goal to balance the right security investments with the right bottom line outcomes.
