IT Desktop Support Engineer

About RHAELM RHAELM is the sovereign AI cloud built to accelerate secure AI deployment at scale, combining power and infrastructure pipelines with global capability and local, in-country operations. Headquartered in London, with deployments across Europe and APAC, we deliver ring-fenced compute, networking, and storage infrastructure alongside a sovereign platform and flexible Bare Metal, Kubernetes, and AI-as-a-Service models. Focused on regulated and mission-critical sectors including Government, Defence, Healthcare, and Financial Services, we give organisations sovereign control over their AI infrastructure, platform, and data.

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.

You will own incidents from first contact through to resolution, manage the hardware lifecycle for end-user devices, and work closely with regional and global IT teams to keep local support aligned with RHAELM's wider infrastructure standards. 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.
