Job description

Join the Future of Engineering: FEA/CFD Simulation & Design Engineer Wanted at STL Engineering!

*Must have Canadian Citizenship or have a valid Permanent Resident Card and a Driver’s License

STL Engineering is a leading Electro-Mechanical Engineering and Design services provider based in Ottawa, ON. Specializing in Hardware, Mechanical, Fluid Flow, Thermal, and Structural Analysis for rugged applications, we are committed to delivering innovative solutions to our clients' engineering challenges.

Role Overview

The FEA/CFD Simulation & Design Engineer is responsible for the end-to-end design, analysis, and validation of ruggedized electronic products and systems for harsh environments. This role combines hands-on product development with advanced analytical evaluation to ensure designs are robust, manufacturable, and compliant with industry standards. The engineer will collaborate with cross-functional teams, suppliers, and customers to deliver innovative, durable, and cost-effective solutions.

Design & Development

• 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.

Analysis & Validation

• 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.

Testing & Compliance

• 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.

Collaboration & Continuous Improvement

• 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.

Qualifications

• Education: Successfully completed Mechanical Engineering program, or a related field.


• Technical Skills: Exposure to Simulation tools (e.g., SolidWorks Simulation, SolidWorks Flow Simulation, FEMAP, CREO Lite, FloTherm, IcePak, Ansys).Experience with CAD software (e.g., SolidWorks, CREO) a plus.


• Knowledge: Understanding of mechanical systems, electronics, control systems, and robotics.


• Problem-Solving: Excellent analytical and problem-solving skills with the ability to troubleshoot complex systems.


• Communication: Strong verbal and written communication skills, with the ability to convey technical information clearly and concisely.


• Attention to Detail: High level of accuracy and attention to detail in all aspects of design and documentation.


• Teamwork: Ability to work effectively in a collaborative, fast-paced team environment.
