Position Overview:

As Fonoa grows, we seek an IT Engineer to help us scale internal IT processes and deliver outstanding support to our globally distributed team.

You’ll play a key role in shaping how we approach IT across the company—working closely with teams like People Ops, Finance, Legal, Sales, and Engineering to ensure everyone has what they need to do their best work.

We rely on Google Workspace, Slack, Zoom, and other third-party tools to connect and get things done. Our fleet consists primarily of Macs, with a mix of Windows and Linux laptops in the wild.

This role is ideal for someone who enjoys wearing multiple hats. On any given day, you might be onboarding a new joiner, responding to IT support requests, improving internal processes, exploring ways to enhance security, or automating something that used to take hours. You will also be part of the on-call rotation for urgent IT and Security requests.

If you’re passionate about helping people, love automation, and care deeply about good IT practices—we’d love to hear from you.
