About Dominion Dynamics
Dominion Dynamics is at the forefront of revolutionizing Canada’s defence sector, developing cutting-edge software-defined, attritable, and sovereign systems.
We envision a future where military strength is derived not merely from sophisticated platforms but through the agile coordination of adaptable, AI-driven capabilities across various domains. We are constructing a cohesive family of systems that not only operate efficiently with our operators but also align with Canada’s democratic values and are designed from the ground up to ensure sovereignty.
Our pace is swift, and we engage directly with the Canadian Armed Forces, particularly in Arctic operations, all while upholding Canadian law and treaty commitments with the utmost respect.
Our founding team consists of seasoned professionals from Anduril, Google, Amazon, and the Canadian Armed Forces. We are committed to developing advanced technology in challenging environments and seek system-level thinkers who excel at the intersection of autonomy, aerospace, and national security.
Why This Role is Essential
The systems we build are engineered for relentless operation in extreme, remote, and mission-critical settings where reliability is imperative. The distinction between a laboratory prototype and a deployed capability lies in the robust enclosure and structure that safeguard sensitive electronics, manage thermal dynamics, and endure rigorous missions. This position is responsible for transforming system specifications into sealed, EMI/EMC-compliant, thermally stable, and manufacturable housings and chassis suitable for mass production and field servicing.
Your Responsibilities
Design and create mechanical structures, enclosures, and protective housings for electronic components, sensors, and circuit boards.
Conduct structural and thermal analyses to ensure durability, vibration resistance, and environmental safeguarding.
Develop detailed CAD models using SolidWorks, alongside comprehensive engineering calculations and design documentation that adhere to engineering standards.
Collaborate closely with electrical and systems engineers to enhance mechanical-electronic integration, including grounding and shielding considerations.
