Mold Design engineer; Plastic Injection Molding

Overview

The Modular Tooling Platform Designer is responsible for architecting and advancing Pak Tech’s next-generation modular tooling platform. This position develops a scalable, standardized, and reusable tooling ecosystem for injection-molded HDPE multipack handles and components. The role establishes and drives platform-based tooling strategies, modular mold architecture, and a high-efficiency asset utilization mindset across all tooling initiatives. The Designer focuses on system-level solutions by implementing common mold base strategies, insert standardization, interchangeable cavity systems, and tooling reuse methodologies.

While still responsible for mold design execution, this role prioritizes building a cohesive tooling platform that enables faster product launches, reduced capital investment, and flexible, high-volume manufacturing.

• Owns and drives Pak Tech’s platform-based tooling strategy aligned with long-term product and manufacturing goals.
• Designs and develops modular mold architectures that enable scalability, repeatability, and rapid deployment across product lines.
• Establishes and standardizes common mold base strategies, insert standardization, and interchangeable cavity systems to improve efficiency and flexibility.
• Develops and executes tooling reuse strategies to maximize asset utilization and minimize redundant capital investment.
• Designs and optimizes injection molds for HDPE multipack handles within the modular tooling platform, including full mold layouts (gating, cooling, venting, ejection).
• Creates 3D models, assemblies, and detailed drawings in Solid Works with a focus on system-level design and manufacturability.
• Collaborates with Product Development, Manufacturing Engineering, and tooling vendors to ensure alignment with platform standards through design, build, and validation.
• Drives continuous improvement through DFM, tolerance analysis, and root-cause problem solving, focusing on scalable, system-level solutions.

• Manages special projects assigned by the Industrial Design
• Performs all other duties as assigned.

• Systems-thinking mindset with the ability to design scalable, standardized solutions.
• Strong communication skills with the ability to influence cross-functional stakeholders.
• High attention to detail with a focus on consistency and repeatability.
• Effective time management and organizational skills.
• Ability to adapt to changing priorities in a fast-paced environment.
• Strong analytical and problem-solving abilities.
• Collaborative mindset with cross-functional teams.

• Associate’s or Bachelor’s Degree in Mechanical Engineering, Tool Design, Manufacturing Engineering, or related field preferred; equivalent experience considered.
• 5+ years of experience in plastic injection mold design, preferably in high-volume or consumer packaging environments.
• Demonstrated experience beyond mold design, including work with modular tooling, standardized systems, or reusable tooling strategies.
• Advanced Solid Works proficiency, including complex assemblies and system-level design.
• Strong understanding of injection molding processes, particularly HDPE materials and high-volume production requirements.
• Experience with DFM, GD&T, tolerance analysis, and mold construction fundamentals. Ability to interpret engineering drawings, specifications, and manufacturing requirements.
• Strong analytical and problem-solving skills.
• Effective communication and collaboration skills across engineering, tooling, and production teams.

• Experience developing or scaling modular tooling platforms in a production environment.
• Experience with high-cavitation, high-throughput molding systems.
• Familiarity with hot runner systems, valve gates, and advanced cooling strategies.
• Experience with mold flow simulation tools (Moldflow, Moldex3D).
• Demonstrated success driving tooling standardization across an organization.
• Understanding of sustainable materials, including recycled HDPE.
• Background in consumer packaging, beverage systems, or similar high-volume industries.
