Mechanical Engineer

About the role

Cornelisnetworks is currently looking for a skilled Mechanical Engineer to become part of their growing engineering organization based in Wayne, Pennsylvania. This full-time role centers on the design, analysis, and optimization of mechanical systems that support the company's core product lines. The engineer will work closely with multidisciplinary teams to translate conceptual ideas into producible, high-quality mechanical designs. The position demands both independent problem-solving and strong teamwork across departments to deliver projects on schedule.

Key facts

What you'll do

• Design and develop new mechanical components and subsystems using industry-standard CAD modeling software and engineering best practices.
• Perform detailed stress, thermal, and fatigue analyses using finite element methods to ensure product reliability and safety standards.
• Create comprehensive technical drawings, bills of materials, and assembly instructions that clearly communicate design intent to manufacturing partners.
• Evaluate and qualify external vendors by reviewing their proposals, capabilities, and quality processes for mechanical part sourcing.
• Build and test physical prototypes, then systematically document test outcomes to guide iterative design improvements and refinements.
• Coordinate with electrical engineers and software developers to ensure effective mechanical and electronic integration across product platforms.
• Revise and maintain existing mechanical designs as new requirements emerge, regulatory standards change, or customer feedback is received.
• Investigate field failures and manufacturing defects through structured root cause analysis, then implement lasting corrective actions.
• Provide direct technical support to production floor personnel when mechanical issues arise during the manufacturing process.
• Compile thorough engineering documentation and present project progress, findings, and recommendations to leadership and cross-functional stakeholders.
• Prioritize and manage several concurrent engineering projects, ensuring each stays within its allocated timeline, budget, and quality targets.
• Contribute to formal design review sessions by offering detailed technical critiques and actionable suggestions to fellow engineers.

Requirements

• A bachelor's degree in Mechanical Engineering, Mechanical Engineering Technology, or a closely related engineering discipline from an accredited institution.
• Demonstrated proficiency with three-dimensional CAD software such as SolidWorks, Autodesk Inventor, or Siemens NX for creating detailed models.
• Working knowledge of geometric dimensioning and tolerancing, engineering drawing standards, and mechanical design conventions used in industry.
• Hands-on experience with finite element analysis, computational fluid dynamics, or other simulation tools to predict real-world performance.
• Excellent written and verbal communication abilities for preparing clear technical reports, presentations, and cross-team correspondence.
• Proven capacity to work independently, set priorities, and manage competing tasks in a fast-paced and deadline-driven environment.
• Familiarity with common manufacturing processes including computer numerical control machining, metal casting, and plastic injection molding techniques.
• Willingness to travel on occasion to supplier facilities, manufacturing sites, or customer locations to support field activities.

Nice to have

• Prior exposure to programmable logic controllers, electromechanical actuators, or motion control subsystems in a product environment.
• Working knowledge of quality management systems such as ISO 9001 or AS9100 and their application in engineering workflows.
• Previous professional experience in a regulated sector including medical devices, aerospace components, or industrial automation equipment.
• Programming ability in Python, MATLAB, or similar scripting languages to automate repetitive engineering calculations and data processing tasks.

Skills & tools

• SolidWorks, CATIA, Creo, or other three-dimensional parametric CAD platforms for part and assembly modeling.
• ANSYS Mechanical, Abaqus, or comparable finite element analysis software for structural and thermal simulation work.
• Microsoft Office Suite, with particular emphasis on Excel for data analysis and PowerPoint for technical presentations.
• Product lifecycle management and document control systems for maintaining versioned engineering files and revision histories.
• Thorough understanding of geometric dimensioning and tolerancing symbols, annotations, and their interpretation on engineering drawings.
• Basic familiarity with electrical schematics, circuit concepts, and systems-level integration considerations in mechatronic products.

Practical notes

• This position is headquartered in Wayne, Pennsylvania and requires regular on-site attendance at the company office.
• The Mechanical Engineer will report directly to the Engineering Manager and work within the mechanical design engineering group.
• The standard work schedule is full-time, with additional hours expected during critical project milestones and product launch periods.
• Cornelisnetworks provides a comprehensive benefits package that includes health and dental insurance, retirement savings options, and paid time off.
