Associate Information Systems Administrator

As an Associate Information Systems Administrator, you will be an entry-level member of Aptima’s internal Information Systems Operations team. You will provide hands-on administration and technical support for managed endpoints, identity and access services, collaboration tools, and other corporate systems while learning Aptima’s technical standards, security requirements, and operating procedures.

This position is primarily focused on Aptima’s company-wide internal operations rather than assignment to a single customer or base environment. The role combines responsive employee support with routine platform administration and serves as a technical escalation resource for issues involving managed endpoints, identity, access, collaboration platforms, and corporate applications. You will complete assigned work within established procedures, document activity, communicate progress, and engage more experienced administrators when an issue exceeds your access, experience, or authority. As your proficiency and clearance readiness develop, you may also contribute to approved project or customer support assignments.

Your work will help keep Aptima’s employees productive and its technology environment secure - from onboarding and endpoint readiness through troubleshooting, access changes, equipment lifecycle, and daily support. You will also help test, document, administer, support, and improve purpose-built internal tools, including Aptima’s Microsoft 365-based ITIL/service-management solution and secure remote-support tooling.
