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. Youll 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.
• Youre 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.
• Youre 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, well reach to schedule 2-3 short technicals. After, well schedule an onsite in our office, where youll work on a small project, discuss ideas, and meet the team.
