# Software Engineer, Security

Cursor

Our mission is to automate coding. The first step in our journey is to build the best tool for professional programmers, using a combination of inventive research, design, and engineering. Our organization is very flat, and our team is small and talent dense. We particularly like people who are truth-seeking, passionate, and creative. We enjoy spirited debate, crazy ideas, and shipping code.
ABOUT THE ROLE
Security Software Engineers help us ship secure products end-to-end—covering enterprise security, cloud/infrastructure, and protections embedded directly in our products. You’ll build the tools and features that safeguard our platform and editor and protect our customers.
YOU MAY BE A FIT IF
• You are a strong software engineer first, with security as your superpower.
• You think like both a builder and an attacker: you anticipate vulnerabilities before they become issues.
• You care about developer experience, building solutions that are secure and frictionless.
• You’re comfortable moving quickly, owning problems end to end, and iterating with limited guidance.
• You have experience building or scaling secure systems in fast-moving environments.
• You have strong opinions on secure defaults, but can balance pragmatism with rigor.
• You enjoy working on small, high-talent teams where impact is magnified.
• You’re motivated by protecting developers and users, and you see security as an enabler.

SAMPLE PROJECTS INCLUDE
• Build AI augmented code review to get involved in important systems at the right time
• Build a least-privilege and JIT system for cloud access that enables engineers and enforces least privileges.
• Implement a safe environment for agents to engage with code
• Implement a framework for securely handling agent manipulation of user systems (e.g., MCP tool calls and command execution).
• Implement a paved road for preventing inappropriate data from being logged
APPLYING
If there appears to be a fit, we'll reach to schedule 2-3 short technicals. After, we'll schedule an onsite in our office, where you'll work on a small project, discuss ideas, and meet the team.
