Cloud Security Engineer

YGO.ai is a VC-funded AI tourism platform. We are hiring a Cloud Security Engineer to own the security of our cloud platform, the APIs our enterprise clients run on and the company itself.

🛡️ About this role. The role carries two things at once. You own security engineering directly and hands-on. You build the security function around it as we grow. At […] a pod lead is a squad leader and a spokesperson, close to the work and close to the client, rather than a full-time manager. You will not stop being an engineer.

The work is broad. You might review source code in the morning, investigate an endpoint alert after lunch and help design a new authentication flow the next day. You identify the highest-risk problems, decide what happens first and execute.

We serve major travel enterprises and we have enterprise commitments going live from the start of 2027. Security is a condition of that business, not a layer added afterwards.

🧑‍💻 What you'll own

Application security. Hands-on code and architecture review across our APIs, backend services and internal tooling. Targeted penetration testing to validate issues yourself. Working with engineers on root causes and practical fixes rather than handing over reports. Vulnerability management and the external penetration tests we commission

Detection and response. Knowing we are under attack while it is happening and what happens next. Alerting, intrusion detection, incident process and the on-call path

Cloud and platform hardening. Ac
