This Role

As IT Desktop Support Engineer, you will be the first point of contact for RHAELM's Japan-based staff, keeping laptops, desktops, mobile devices, and collaboration tools running reliably across our Tokyo office and remote workforce.

It is a hands-on role with real ownership, in a business where reliable IT underpins the trust our regulated-sector clients place in us.
