    Position Summary

    The Systems Administrator – Infrastructure & End User Operations is a hands-on technical role responsible for maintaining and improving Opportune's core systems, Microsoft cloud environment (M365/Azure), endpoint management, and SaaS applications while supporting day-to-day end-user operations.
