Team: Technology Services (Information Technology)
Reports To: Senior Infrastructure Engineering Manager
Location: Toronto, Ontario. (4 days in office, 1 day remote)
Employment Type: Permanent Full-Time
About 123Dentist
123Dentist is the largest majority Canadian-owned dental support organization, supporting a growing network of 400+ dental practices across the country. As we continue to expand, both organically and through acquisition, our IT team plays a central role in standardizing, securing, and scaling the technology that our clinics and corporate teams rely on every day.
About The Role
The Infrastructure Architect is the senior technical engineer for 123Dentist’s server, identity, cloud, and network infrastructure, combining deep hands-on design and engineering with escalation support and project delivery across a Microsoft-centric, multi-site environment.
The role is balanced across three areas: infrastructure transformation and project delivery (cloud migrations, identity modernization, endpoint-management standardization), Tier 2/3 escalation support for the most complex infrastructure, identity, cloud, and network issues, and mergers & acquisitions / practice integration, onboarding newly acquired practices into the 123Dentist environment. Operating with significant independence, you’ll act as a trusted technical authority, mentoring infrastructure engineers, service desk analysts, and operations team members while championing sound engineering standards, security, and reliability.
