.

Our engineers drive packaging innovation, creating new ways to improve performance and exceed customer expectations. We’re passionate about designing equipment that not only meets but anticipates market needs, working closely with peers across sales, manufacturing, and assembly.

Ossid LLC, powered by Pro Mach, is a recognized leader in automated manufacturing systems for the food and medical device packaging industry. Our portfolio includes horizontal thermoform, fill, and seal machinery, automatic weighing and labeling systems, high‑speed tray sealing, and tray overwrap equipment.

The Senior Mechanical Design Engineer will lead the design and development of custom and standard packaging machinery for new designs and provide product improvement support for existing designs. The engineer will manage the full project lifecycle—from concept through final testing and customer delivery—while ensuring designs are robust, manufacturable, and meet customer requirements. This role requires close collaboration with cross‑functional teams—including manufacturing, controls, and service—to deliver innovative and reliable packaging solutions.

• Lead packaging machine design projects from concept through final testing, following Ossid’s Engineering Development Process and Stage Gate Process.
• Develop 3D CAD models, layouts, BOMs, and detailed drawings for mechanical systems and assemblies.
• Work collaboratively with Product Line Managers, manufacturing, assembly technicians, electrical/controls engineering, and service teams to ensure design integrity, manufacturability, and ease of maintenance.
• Apply a strong understanding of controls system components and machine automation (motors, sensors, actuators, pneumatics, etc.) to influence mechanical design decisions.
• Actively seek and incorporate feedback from colleagues, manufacturing, and testing teams to improve designs and processes.
• Oversee prototype build, debugging, and final machine testing; incorporate manufacturing and testing feedback into final designs.
• Ensure all design activities meet Ossid’s documentation standards, design reviews, and stage gate requirements.
• Mentor engineers, contribute to design standards, and recommend process improvements to enhance quality and efficiency.
• Analyze and evaluate competitive products for best application use.
• Participate in machinery assembly testing to identify and solve improvements needed to satisfy customer requirements.
• Process ECNs and other engineering documents required to maintain databases and support records.

Ossid offers an open, communicative environment that encourages individual initiative and professional growth. We provide a comprehensive benefits package for all employees, including competitive salary, medical/dental coverage, life insurance, generous paid time off, and a retirement savings plan with employer match. All benefits are effective on your first day of employment.

• 7+ years of mechanical design experience in packaging machinery, industrial equipment, or related capital equipment industry.
• Proven experience managing projects through formal development processes (Stage Gate, VA/VE, or other Engineering Development processes).
• Strong proficiency in 3D CAD (Solid Works preferred) and PDM/Data Management systems.
• Solid understanding of machine controls components (motors, drives, sensors, pneumatics, HMIs, PLC interfaces) and their impact on mechanical design.
• Hands‑on experience with manufacturing processes, fabrication methods, and design for manufacturability (DFM).
• Excellent problem‑solving, organizational, and communication skills.
• Ability to lead cross‑functional teams and manage multiple projects simultaneously.
• Self‑motivated and adaptable to work independently or within a team.
• Comprehensive knowledge of machine and tooling design.
• Effective written and verbal communication skills.
• Strong organizational and detail‑oriented aptitudes.

• Well‑disciplined engineering principles and standards.
• Simulation and material analysis experience.
• Desire to be hands‑on with machinery and equipment.
• GD&T experience.
• Experience with MRP/ERP systems and multi‑level BOM structures.
