Exposure to Simulation tools (e.g., SolidWorks Simulation, SolidWorks Flow Simulation, FEMAP, CREO Lite, FloTherm, IcePak, Ansys).
Understanding of mechanical systems, electronics, control systems, and robotics.
Excellent analytical and problem-solving skills with the ability to troubleshoot complex systems.
Strong verbal and written communication skills, with the ability to convey technical information clearly and concisely.
High level of accuracy and attention to detail in all aspects of design and documentation.
Ability to work effectively in a collaborative, fast-paced team environment.
Willingness to learn new skills and adapt to changing project requirements and priorities.
Canadian Citizenship or have a valid Permanent Resident Card and a Driver’s License.

Nice To Haves

Experience with CAD software (e.g., SolidWorks, CREO) a plus.

Responsibilities

Perform design of rugged electronic products, including enclosures, PCBs, connectors, and assemblies.
Translate customer and system requirements into technical specifications and design solutions.
Generate detailed CAD models, assemblies, and drawings with manufacturing and assembly considerations.
Select appropriate materials, coatings, and finishes for durability in extreme environments.
Perform analytical modeling and simulations (thermal, mechanical stress, vibration, EMI/EMC).
Conduct tolerance analysis, fatigue assessments, and ruggedization trade studies.
Support verification and validation activities, ensuring compliance with standards (MIL-STD, DO-160, IP ratings, etc.).
Provide data-driven recommendations to optimize ruggedness, cost, weight, and manufacturability.
Partner with test engineers to design and execute environmental testing (temperature, vibration, ingress protection, EMI/EMC).
Document and analyze test data, providing detailed reports and recommendations.
Support failure analysis, root cause investigations, and corrective action implementation.
Ensure requirements traceability and compliance across design and testing phases.
Work closely with internal teams (mechanical, electrical, firmware, manufacturing) to align design and analysis objectives.
Engage suppliers and test labs to ensure manufacturability and certification compliance.
Participate in design reviews, risk assessments, and FMEA activities.
Contribute to knowledge sharing and continuous improvement of ruggedization techniques and best practices.
