Description
Senior IT Systems Engineer
Location: UK Remote - Occasional Onsite Office in London (Paddington)
Role Overview
Nasuni is hiring a Senior IT Systems Engineer to own and continuously improve the core systems that power our internal IT environment. This role sits between traditional systems administration and infrastructure engineering—focused on building, optimizing, and scaling critical IT platforms such as identity, endpoint management, and collaboration tools.
You will be responsible for the performance, reliability, and evolution of systems including Okta, Jamf/Intune, Atlassian (Jira/Confluence), and core SaaS platforms. This is a hands-on engineering role—not a support function—focused on improving how systems operate at scale.
This role is ideal for engineers who enjoy working behind the scenes to strengthen systems, automate workflows, reduce vulnerabilities, and improve how IT platforms function across a distributed organization.
This role is not for candidates who prefer purely support-based work or limited ownership environments.
