• Create and revise 3D CAD models, assemblies, and detailed part drawings using SolidWorks.
• Review engineering drawings, identify issues, and implement corrections to ensure accuracy and clarity.
• Assist with engineering documentation and provide inputs to the Engineering Change Order (ECO) process.
• Research mechanical components, materials, fabrication methods, and potential suppliers to support design and manufacturing decisions.
• Build, assemble, troubleshoot, and test prototypes, fixtures, and engineering samples.
• Prepare test setups, collect and analyze test data, and draft test procedures and reports to support design verification activities.
• Maintain accurate records for parts, assemblies, bills of materials, and configuration data throughout the product lifecycle.
• Participate in design reviews and clearly communicate technical progress, results, risks, and issues to the broader team.
• Follow company quality procedures, safety practices, and applicable design control requirements in all engineering activities.
• Contribute to continuous improvement of design, documentation, and change control processes within the engineering team.

• Bachelor’s degree in Mechanical Engineering, Biomedical Engineering, or a related engineering discipline.
• Up to 2 years of relevant experience, including internships, co-op assignments, academic design projects, or equivalent hands-on technical experience.
• Ability to create 3D models, assemblies, and 2D drawings using standard dimensioning practices.
• Experience using SolidWorks for mechanical design, modeling, and drafting.
• Foundational understanding of mechanical design principles, materials, statics, mechanics, heat transfer, and tolerance principles.
• Basic knowledge of geometric dimensioning and tolerancing (GD&T) and its application to engineering drawings.
• Hands-on experience with prototyping, laboratory tools, test equipment, or 3D printing gained through work or academic projects.
• Familiarity with common fabrication processes such as machining, sheet metal, molding, and additive manufacturing.
• Basic data analysis and problem-solving skills, including experience with spreadsheets and engineering analysis tools.
• Strong attention to detail, organizational skills, curiosity, and a willingness to learn in a multidisciplinary environment.
• Ability to follow established quality procedures, safety practices, and design control processes.

• Exposure to medical device development, quality systems, design controls, or other regulated industries is a plus.
• Experience with scripting or programming tools for data analysis or engineering calculations is beneficial.
• Familiarity with engineering change order (ECO) processes and configuration management practices.
• Experience participating in structured design reviews and presenting technical findings.
• Interest in working with 3D visualization and guidance systems for microsurgery.
• Motivation to grow into increasing levels of responsibility, including ownership of projects over time.
• Appreciation for a structured training program and the opportunity to develop independence in technical work.

The role is based in a fast-paced engineering environment focused on the development of advanced medical instruments and 3D visualization systems for microsurgery. You will work closely with multidisciplinary teams, including mechanical, electrical, optical, software, systems, manufacturing, and product professionals, and will regularly use tools such as SolidWorks, laboratory equipment, test fixtures, and prototyping tools, including 3D printers. The environment emphasizes adherence to quality procedures, safety practices, and design control requirements typical of regulated product development. The culture supports structured training, opportunities to gain independence, and clear pathways for growth and promotion as you take on more complex projects and responsibilities.
