What You’ll Do

We are seeking an IT Admin to administer the collaboration, service management, and automation platforms that Horizon3 teams use every day. The Business Applications (BizApps) team is the operational backbone for organizational collaboration, system connectivity, and process automation at Horizon3. We partner with every department to provide the platforms, guardrails, and integrations that eliminate manual toil safely and efficiently. We own and administer Jira, Jira Service Management (JSM), Confluence, Rovo, Loom, Glean, and our citizen development platform, Workato. We hold ourselves to least-privilege access, data privacy, and auditable data flows in everything we build.

In this role, you will administer our non-AI tooling: Jira, JSM, Confluence, Loom, and the support layer around Workato and our citizen development platform. You will handle permissions and provisioning, configure projects and workflows, and take on advanced configuration such as JSM SLAs, custom fields, and automations. You will scope and complete moderately complex improvements with little direction.

This is an individual contributor role reporting to the Senior Manager, Business Applications.

• Resolve access, permission, and configuration requests from cross-functional teams

• Configure projects, workflows, screens, custom fields, and automation rules in Jira and Confluence to meet team requirements

• Configure JSM request types, queues, forms, and SLAs, and tune them using ticket and SLA performance data

• Scope and deliver moderately complex improvements end to end, from requirements through rollout and documentation

• Monitor Workato recipe runs, triage failures, and fix or escalate issues to the Senior Engineer with clear diagnostic detail

• Support citizen developers by onboarding builders, provisioning sandboxes and service accounts, and applying approved templates and guardrails

• Apply role-based access control (RBAC) and least-privilege access across owned platforms, and run periodic access and license reviews

• Identify repetitive administration tasks and automate them to reduce manual toil

• Maintain knowledge base articles, runbooks, and configuration documentation

• Report on license utilization, request volume, and platform health to the Senior Manager

• Demonstrate a commitment to integrity, process improvement, and customer satisfaction

What You’ll Bring

• Must have hands-on experience administering Jira and Confluence, or comparable work management or ITSM platforms, in an organization with multiple teams

• Must have experience configuring workflows, custom fields, and automation rules beyond default settings, including service management SLAs or equivalent

• Must have working knowledge of RBAC and least-privilege access, and experience managing permission schemes and user lifecycle on SaaS platforms

• Must have experience managing a request queue and resolving access and configuration issues within service levels

• Must be able to scope, plan, and complete moderately complex projects with little direction from a manager

• Must be able to write clear documentation and user guidance for technical and non-technical employees

• Must be able to read and troubleshoot integration or automation logs well enough to isolate a failure and escalate it with useful detail
