Core Responsibilities

The day-to-day work of a Mechanical Engineering Co-op is dynamic and project-driven. While specific tasks vary by industry and team, the core responsibilities revolve around supporting the engineering product lifecycle.

Primary Functions

Assist senior engineers in the design and development of mechanical components and systems using 3D CAD software such as SolidWorks, CATIA, or Creo.
Create and revise detailed 2D engineering drawings, ensuring adherence to established standards and the proper application of GD&T (Geometric Dimensioning and Tolerancing) principles.
Participate in the entire product development lifecycle, from initial concept brainstorming and sketching to detailed design, prototyping, and validation.
Build and assemble physical prototypes of new designs using hand tools, power tools, 3D printers, and basic machine shop equipment like lathes and mills.
Develop and execute comprehensive test plans to validate the performance, reliability, and durability of mechanical systems and components against design requirements.
Set up test apparatus, install instrumentation and sensors (e.g., strain gauges, thermocouples, accelerometers), and utilize data acquisition (DAQ) systems to collect experimental data.
Analyze and interpret test data, summarize key findings in formal technical reports, and present results and actionable recommendations to the engineering team.
Perform foundational engineering analyses, including stress analysis (FEA), thermal modeling, and tolerance stack-up calculations, under the guidance of experienced engineers.
Collaborate with the manufacturing team to understand Design for Manufacturability (DFM) and Design for Assembly (DFA) principles and incorporate them into new designs.
Support the creation and maintenance of a detailed Bill of Materials (BOM) for assemblies, ensuring the accuracy of part numbers, quantities, and supplier information.
Troubleshoot and diagnose failures in existing products or test fixtures, performing root cause analysis to identify and resolve underlying mechanical issues.
Research and evaluate new materials, off-the-shelf components, and emerging technologies to support innovation, performance improvement, and cost-reduction initiatives.
Design and develop custom jigs, fixtures, and tooling required for manufacturing, assembly, or testing processes to improve efficiency and repeatability.
Manage and organize CAD files, engineering documents, and test data within the company's Product Data Management (PDM) or Product Lifecycle Management (PLM) system.
Communicate with external vendors and suppliers to source components, obtain quotes, and clarify technical specifications for custom parts.
Actively contribute to formal design reviews by preparing presentation materials, presenting design concepts, and diligently documenting feedback and action items.
Automate repetitive data analysis tasks or create simple calculation tools using scripts in software like MATLAB, Python, or Excel VBA.
Support continuous improvement efforts on the production line by identifying process inefficiencies, ergonomic challenges, or quality issues and proposing mechanical solutions.
Conduct competitive product teardowns and benchmarking analysis to understand market trends and the technical advantages of competitor technologies.
Prepare and maintain clear, concise documentation for assembly procedures, test methods, and standard operating procedures (SOPs).

Secondary Functions

Assist in the procurement of components and materials by interfacing with suppliers and helping manage the bill of materials (BOM).
Contribute to the organization and maintenance of the engineering lab, workshop, and testing facilities.
Collaborate with cross-functional teams, including electrical, software, and manufacturing engineering, to ensure project alignment and integration.
Participate in sprint planning and agile ceremonies within the engineering team to foster an adaptive and responsive development process.
