Sinara Consultants is actively seeking proficient, versatile, and curious application or systems engineers to join our technical operations team.

A key purpose of the role is to provide technical support for our Sinara-built applications 24 hours a day, as such the position involves working beyond standard business hours, on a shift pattern rotating between evenings, overnight and early morning shifts with opportunity for some daytime shifts.

Your responsibilities will include maintaining our mission-critical applications, delivering both primary and secondary application management support within our cloud-based and on-premise environments, as well as providing third-line technical support for Sinara software applications to a variety of customers.
