Office Manager H/F - Temps Complet

Office Manager, Toronto
Location: Toronto ,ON (On-Site)
Type: Full-time

Dominion Dynamics is building tomorrow’s technology today: sovereign, next-generation defence systems for the harshest environments on Earth.
We’re delivering a software-defined command and control capability that lets Canada and its allies see, respond, and defend across every domain, starting in the Arctic, where extreme cold demands technology no one else can deliver.
From prototype to deployment in months, we move fast, co-develop with operators, innovate at the edge, and test in our North.
Our founding team includes veterans from Anduril, Google, Amazon, and the Canadian Armed Forces. We’re building hard tech in hard places, and we're looking for system-level thinkers who thrive at the intersection of autonomy, aerospace, and national security.

As we expand into Toronto, we need someone on the ground who owns the office end-to-end. You will be the backbone of the office, creating structure, supporting leaders, and keeping day-to-day operations running without friction.
