About The Position

In this role, you’ll have ownership over a wide range of IT and OT systems, playing a key part in keeping Rodan’s technology environment secure, reliable, and high‑performing. From networks and servers to cloud platforms and cybersecurity systems, your work directly supports business continuity, compliance, and end‑user productivity. You’ll operate in a hybrid on‑premise and cloud environment, with strong emphasis on Microsoft Azure, Intune, and Microsoft 365 security services. This role offers hands‑on exposure to modern infrastructure and security tooling, making it ideal for professionals who want to stay current while working at enterprise scale. Security is central to this role. You’ll implement and evolve modern security practices such as Zero Trust and identity governance, contribute to cybersecurity operations, and help ensure systems meet high standards for resilience and compliance. Your expertise will be trusted and relied upon. You’ll be encouraged to streamline workflows through automation and scripting, helping improve efficiency, reduce risk, and modernize how systems are managed. This is a role where initiative and continuous improvement are valued - and acted on. As a senior technical role supporting critical systems, occasional after‑hours support is part of ensuring continuity during key system events, security incidents, or planned maintenance - providing meaningful responsibility and trust, not routine disruption.
