About the role
Mechanical Engineering Technician (Prototype & Low-Volume Manufacturing) Preferred Location: Ottawa Reports to: Head of Hardware Type: 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. Why This Role Matters As Dominion builds sovereign autonomous systems, speed of execution matters just as much as engineering quality. This role bridges the gap between concept and reality — turning CAD, prototypes, and engineering ideas into functional hardware that can be tested, iterated, and deployed quickly. You will help accelerate product development by building, machining, assembling, and refining mission-critical systems in a highly hands-on environment where rapid iteration and practical problem-solving are essential.
The Role: Mechanical Engineering Technician (Prototype & Low-Volume Manufacturing) This is a highly hands-on builder role focused on prototyping, fabrication, machining, and early-stage manufacturing. You’ll work closely with engineers and product teams to move quickly from concept to physical hardware, supporting everything from one-off prototypes to low-volume production builds. You’ll operate across machining, welding, additive manufacturing, composites, assembly, inspection, and tooling, helping shape products that are designed for real-world deployment in demanding operational environments. What You’ll Do Collaborate closely with engineers to rapidly iterate designs and provide feedback on manufacturability, tolerancing, and material selection Fabricate and assemble mechanical prototypes using machining, welding, and general shop processes Program, set up, and operate CNC mills and lathes to produce precision components from CAD models and engineering drawings Develop and optimize CAM toolpaths, machining strategies, feeds, and speeds for prototype and short-run production Perform dimensional inspections using metrology equipment and validate components against GD&T
