Cloud Engineer / Integration Engineer

We're looking for a senior all-rounder for two to three months, who can start as soon as possible.
We're building an enterprise operating platform, with a go-live date that's already circled in red. We need one experienced pair of hands across cloud infrastructure and security, event-driven integration, and data platforming.
You don't need to be the deepest expert in all three, but you should be comfortable switching between them in the same week, working from a clear design, and ready to roll up your sleeves.
