Job Description

We are seeking an experienced Senior Mold Design Engineer to serve as the technical lead for complex injection molding programs, with a focus on insert molding, overmolding, and tight-tolerance applications. This role provides technical leadership from initial customer engagement and estimating through development, validation, technology transfer, and commercial launch.

The Senior Mold Design Engineer is the primary authority for mold design, tooling strategy, process selection, and molding technology. This individual defines tooling concepts, recommends materials and equipment, develops scientifically sound validation strategies, and drives design-for-manufacturability decisions that enable reliable, scalable production. The role works directly with customers and cross-functional teams to turn challenging product concepts into robust manufacturing solutions.

Working closely with Commercial, Estimating, Program Management, Quality, Manufacturing, Supply Chain, and Operations, the Senior Mold Design Engineer ensures project scope, technical risk assessments, non-recurring engineering (NRE) estimates, piece part costs, schedules, and technical deliverables are accurate, achievable, and aligned with customer requirements.

Beyond project execution, this individual establishes mold design standards, drives engineering best practices, mentor's technical talent, and strengthens organizational capability in tooling and molding. They are expected to expand technical expertise across the business and elevate the overall performance of the molding organization.

Responsibilities

• Leads the design and development of precision injection molds for medical components, including insert molding, overmolding, multi-material, and other complex or tight tolerance applications.
• Translates customer and product requirements into manufacturable tooling concepts, mold specifications, acceptance criteria, and development plans; leads design-for-manufacturability and technical risk reviews.
• Develops and reviews 3D mold designs, detailed drawings, stack-ups, GD&T, gating, venting, cooling, ejection, steel-safe conditions, component selection, and maintainability provisions using SolidWorks or comparable CAD tools.
• Partners with Commercial, Estimating, and Program Management to define technical scope, tooling and equipment requirements, NRE, capital needs, schedules, piece-part cost assumptions, risks, and supplier deliverables for new opportunities.
• Provides technical direction to external mold builders and internal teams through design review, build, sampling, debug, acceptance, transfer, and production release; holds suppliers accountable for quality, timing, documentation, and performance.
• Leads or supports mold flow analysis, tool trials, process characterization, DOE, capability studies, and validation readiness; ensures tools and processes have robust operating windows before IQ/OQ/PQ and commercial launch.
• Diagnoses and resolves complex tooling, molding, equipment, and part quality issues using structured problem solving, data analysis, and hands-on collaboration with molding engineers, technicians, Quality, and Operations.
• Owns technical recommendations for mold repair, refurbishment, modification, spare components, preventive maintenance, capacity, obsolescence, and lifecycle management to improve uptime, yield, cycle time, and total cost.
• Evaluates and implements new tooling, molding, automation, and inspection technologies; develops equipment and tooling specifications and provides technical leadership for related capital projects.
• Establishes mold design standards, specifications, checklists, technical files, lessons learned, and training materials; mentors engineers, desi
