Full-time About Dominion Dynamics

See everything. Defend what matters.

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. This role ensures the Toronto team operates smoothly, stays organized, and has what they need to execute at speed.

You will be the backbone of the office, creating structure, supporting leaders, and keeping day‑to‑day operations running without friction.

This is not just an administrative role. This is the person who runs our Toronto office.

You’ll own the day‑to‑day operations of the space while supporting leaders with scheduling, coordination, and execution. You’ll create an environment where the team can focus, move fast, and do their best work.

• Own day‑to‑day operations of the Toronto office (space, supplies, vendors, logistics)
• Ensure the office is organized, functional, and running smoothly at all times
• Manage calendars and scheduling for Toronto‑based leaders
• Coordinate meetings, visitors, and on‑site activities
• Support travel planning and logistics as needed
• Help establish and maintain team cadence (meetings, check‑ins, office rhythms)
• Act as the go‑to person for anything office‑related
• Support onboarding for new hires in the Toronto office
• Assist with planning and execution of team events and office moments
• Maintain basic administrative systems, trackers, and documentation
• Jump into ad hoc tasks to keep things moving

• 2–5+ years in an office admin, office manager, or coordination role
• Strong organizational skills and attention to detail
• Ability to manage multiple priorities and keep things on track
• Clear communicator, both written and verbal
• Proactive and reliable; you see what needs to be done and do it
• Comfortable working in a fast‑paced, evolving environment
• High ownership mindset and strong follow‑through
• Positive, team‑oriented attitude

No defence background required.

We've hired people who didn't tick every box. If this is the work you want to do, please apply anyway.

Building something meaningful starts with the right people.

At Dominion Dynamics, you’ll:

• Shape Canada’s future by building real defence capability for the CAF and our allies.

• Have an impact from day one with equity, responsibility, and direct access to leadership.

If you’re curious, hands‑on, and driven by the opportunity to make a difference, this is where you belong!
