Job Description

About Packsize,

Packsize is redefining the way businesses and their customers use and experience packaging around the world. We build the technology, design the right solutions, and automate the processes that propel the industry forward. To us, packaging is much more than a box—it’s delivering what’s right for our customers, their customers, our people, and the planet.

The Role

Packsize is looking for a Mechanical Engineer to join the R&D Hardware team in Louisville, KY. This role is focused on reducing the cost and complexity of Packsize machines through thoughtful engineering analysis, redesign, and system-level optimization.

You will work across mechanical and electrical subsystems to identify opportunities for BOM cost reduction, part simplification, part longevity and increased modularity, while preserving or improving machine performance, reliability, and serviceability.

By lowering material cost, reducing part count, improving reuse, and enabling scalable configurations (modularity), this role plays a direct part in lowering the barrier to entry for customers and improving Packsize’s competitive position.

What You’ll Do

Lead BOM cost-reduction initiatives through redesign of major machine components and subsystems
Analyze existing machine architectures for standardization, simplification, and reuse opportunities
Drive modularity and platform thinking across mechanical and electro-mechanical systems
Partner with Procurement, Service, Quality and Supply Chain to evaluate suppliers, quotations, and cost drivers
Support redesign efforts focused on reduced part count and improved manufacturability
Report out on cost savings goals
Provide system-level design input during design and architecture reviews
Document and implement design changes using ECOs in a PLM system
Collaborate with sustaining and development engineers to balance cost, reliability, safety, and compliance
Participate in testing and validation of redesigned components and assemblies
Support transfer of redesigned systems into production
Engage in continuous improvement activities with a lean mindset

What You’ll Bring

BS/MS in Mechanical Engineering, Manufacturing Engineering, or related field
Experience in industrial machine design or sustaining engineering
Demonstrated experience with design-to-cost or value engineering initiatives
Strong mechanical design background with working knowledge of automation systems
Proficiency in 3D CAD (SolidWorks preferred)
Understanding of DFM, DFA, and design for serviceability principles
Ability to read mechanical drawings, GD&T, and electrical schematics
Experience with PDM/PLM tools and engineering change processes
Strong analytical, communication, and cross-functional collaboration skills

Nice to Have

Exposure to electrical systems, sensors, PLCs, and general industrial controls
Experience working directly with suppliers and contract manufacturers
Background in modular product platforms or configurable machine systems
Hands-on prototyping and machine build experience

A Few Other Things

Up to 15% travel as needed.
