Design Engineer

The Design Engineer I
- Plastics supports the design, development, validation, and launch of injection molded plastic components and assemblies. This role is intended for an early-career engineer who can build foundational expertise across plastic part design, DFM/DFA, material selection, tooling considerations, molding processes, testing, and simulation-informed decision making.

INNOVATE WITHOUT BOUNDARIES

At Milwaukee Tool, our Engineering Teams develop innovative solutions that improve the productivity, safety, durability, and performance of products trusted by professional users every day.

As a Design Engineer I
- Plastics, you will work within cross-functional product development teams to design and improve plastic components from early concept through production launch. The role provides hands-on exposure to plastic part design, materials, tooling, processing, manufacturing, testing, and injection molding simulation workflows.

This position is designed as a development role for an engineer interested in growing practical plastics expertise while contributing to high-impact product development work.

• Design and develop plastic components and subassemblies for new product development and continuous improvement projects.
• Create, maintain, and release 3D CAD models, engineering drawings, specifications, and technical documentation.
• Apply DFM and DFA principles to improve product performance, manufacturability, quality, assembly efficiency, and cost.
• Support design reviews, tolerance reviews, prototype builds, engineering builds, and production launch activities.
• Collaborate with industrial design, product engineering, manufacturing, sourcing, quality, suppliers, and test teams throughout the product development process.

• Support material selection for thermoplastics, elastomers, and related polymer systems based on mechanical, cosmetic, environmental, regulatory, and manufacturing requirements.
• Develop working knowledge of injection molding behavior, including gate location, flow length, shrinkage, warpage, weld lines, sink, knit lines, cooling, ejection, and parting line considerations.
• Review and interpret injection molding simulation results, including Moldflow outputs, to support part design optimization, gating recommendations, filling performance, cooling strategy, and warpage reduction.
• Partner with tooling engineers, molders, suppliers, and manufacturing teams to resolve molding-related design, tooling, and process concerns during prototype and production phases.
• Assist with evaluation of new plastic materials, manufacturing methods, and design approaches for future product applications.

• Support engineering validation and verification testing for plastic components and assemblies.
• Analyze test results, identify design risks, and implement design improvements based on data and engineering judgment.
• Assist in troubleshooting plastic component failures, quality issues, and manufacturing concerns using structured root cause analysis methods.
• Work with materials, quality, tooling, manufacturing, and supplier teams to identify corrective actions and prevent recurrence.
• Support continuous improvement initiatives focused on product reliability, manufacturability, weight, cost, quality, and performance.

• Support multiple projects simultaneously in a fast-paced product development environment.
• Document engineering assumptions, test results, design decisions, tradeoffs, risks, and recommendations clearly and accurately.
• Communicate project status, technical risks, open issues, and design changes to project…
