Mechanical Engineering Technician, Prototype & Low-Volume Manufacturing

Preferred Location: Onsite - Ottawa

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 requirements
Design and build fixtures, jigs, molds, and work-holding solutions to improve repeatability and manufacturing efficiency
Operate and maintain additive manufacturing equipment for rapid prototyping and functional part production
Work with composite materials including carbon fiber and fiberglass, supporting layup, trimming, curing, and finishing processes
Support low-volume manufacturing runs while maintaining quality, consistency, and process documentation
Troubleshoot machining, fabrication, and assembly issues quickly in a fast-paced development environment
Maintain build documentation, inspection records, and revision control throughout the development lifecycle
Contribute to continuous improvement of shop processes, tooling, workflows, and manufacturing practices
Uphold safety standards and maintain a clean, organized, high-functioning shop environment

What You’ll Bring

Diploma or equivalent in Mechanical Engineering Technology or a related discipline
5+ years of hands-on experience in CNC machining, fabrication, and prototype development
Strong experience operating CNC mills and lathes, including CAM programming and G-code fundamentals
Proficiency with CAD software such as SolidWorks
Strong understanding of metrology, inspection techniques, and GD&T interpretation
Hands-on MIG and/or TIG welding experience
Experience with additive manufacturing technologies and rapid prototyping workflows
Experience working with composite materials and fabrication techniques
Experience designing and building tooling, molds, fixtures, or jigs
Demonstrated ability to move quickly from prototype to low-volume production
Strong troubleshooting skills and a practical, builder-oriented mindset
Comfortable operating in a startup, R&D, or fast-paced product development environment
Experience with multi-axis CNC machining, advanced toolpaths, or production scaling is considered an asset
Knowledge of composite curing methods such as vacuum bagging or autoclave processing is considered an asset

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.

Why Join Us

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
Make decisions that ship in a high-trust environment with short feedback loops and rapid iteration
Move fast, field faster, and work directly with the operator — our systems are in the field with the CAF now
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.

Compensation & Benefits

Competitive base salary and company equity
Comprehensive health benefits
Additional equity granted based on impact

We use AI tools to support parts of the hiring process, including screening and reviewing responses. Final hiring decisions are always made by people and follow all applicable privacy and employment laws in Canada.
