Sr. Software Engineer (Frontend) - Extensions Team

At Cerby we believe security is everyone’s business. Collaborating across your apps doesn’t need to be chaos. We are a mission-critical cybersecurity company that empowers your teams to operate securely and control their apps completely. We’ve built our product on the idea that teams deserve autonomy over their work apps. It turns out that why they are guaranteed a choice, security comes naturally.

More than 50% of all technology is spent outside of centralized IT organizations. Individual business units are taking their technology destiny into their own hands, and we enable that. End user onboarded applications are behind more than one third of all cybersecurity hacks. We provide the solution to manage that through enabling users to select their own technology and we automatically protect those applications.

Because the extension injects UI into pages we don't control and brokers our users' most sensitive data, security is not a phase of the work — it *is* the work. You are also expected to embrace AI as a core part of how we build, actively exploring and incorporating AI-assisted tools...
