Security Engineer

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.

• 3–5 years of experience in security engineering, security operations, or related roles in a B2B SaaS or cloud-native environments

• Strong understanding of cloud security practices (AWS, GCP, or Azure), identity management, and secure software development lifecycles

• Hands-on experience with security tooling (SIEM, EDR, IAM, vulnerability scanners, etc.)

• Excellent problem-solving skills, with the ability to balance pragmatism and rigor in a fast-moving startup environment

• Strong written and verbal communication skills; able to work closely with both technical teams and business stakeholders

• Bonus points for experience in incident response, penetration testing, public speaking or publishing papers

• Ensure compliance with regulatory and enterprise security requirements

• Deploy and manage internal security tools and monitoring systems to protect our infrastructure, code, and data

• Conduct risk assessments and threat modeling and recommend mitigations

• Partner with product and engineering teams to embed security best practices into development and operations

• Help define and execute incident response procedures to ensure we can detect, investigate, and respond effectively
