Senior Software Engineer

Company Overview

At Backline, we are building the world’s first autonomous remediation platform - AI agents that don’t just find vulnerabilities, they fix them. At scale. Seamlessly integrated into existing workflows, these agents act as tireless virtual engineers, analyzing code and configurations, generating safe changes, and pushing verified fixes - autonomously. 

The shift we offer is transformative: vulnerabilities vanish in hours instead of months, human teams are freed from endless fire drills, and organizations move from reactive defense to true resilience. Security backlog - a chronic industry pain point - will become a thing of the past.

We have recently closed a significant Seed round led by StageOne Ventures, Gradient and Evolution Equity Capital and our office is located at the Bursa in Ramat Gan, with a hybrid work model.
