Why Aisle?

Aisle is redefining how enterprises secure their software with an AI agent for autonomous vulnerability remediation. Vulnerabilities are the #1 root cause of cyber incidents, yet most organizations take weeks or months to patch what attackers exploit in days. We’re changing that.

Our mission is to protect democratic societies from the most sophisticated cyberattacks. We do that by giving organizations - including those operating critical infrastructure - the power to harden their systems and resolve security issues at superhuman speed and scale. Backed by world-class founders and advisors, we’re creating a new category in cybersecurity at the intersection of AI, automation, and enterprise resilience.

We’re a small, talent-dense team spread across the US, Europe, and Israel. We value high ownership, high velocity, and low-ego collaboration. If you want to work with world-class minds in AI and security, thrive in fast-moving environments, and care about solving one of the toughest challenges in tech, Aisle is the place for you.

• Familiarity with databases (SQL/NoSQL) and messaging/queueing systems

• Hands-on experience with CI/CD pipelines and automated testing practices

• Solid understanding of secure coding principles and interest in cybersecurity

• Bonus: background in AI/ML integration, data pipelines, or enterprise SaaS products

• Contribute to architecture and technical design decisions for scalable, distributed systems

• Build and optimize APIs and services to support AI-driven vulnerability detection and remediation

• Improve the efficiency, scalability, and security of our core platform
