Manufacturing Engineering Manager

Manufacturing Engineering Manager - Busbar

Location: Molex, Monee, IL

The Manufacturing Engineering Manager leads process engineering, design-for-manufacturing (DFM), and tooling for busbar and related products.

This role owns manufacturability through new product introduction (NPI), contract review, and ongoing production by developing repeatable processes, driving disciplined engineering execution, and building a high-performing team that meets customer requirements, manufacturing capabilities, and continuous improvement goals.

What You Will Do:

Contract Review & Launch Readiness


*
+ Own the contract review process to ensure new/revised programs are evaluated and approved for manufacturability, quality, cost, and operational readiness.
+ Coordinate with Sales, NPI, Quality, and Operations to validate requirements and align before launch.
+ Maintain timely, complete, and auditable contract-review packages and ERP documentation.

Process Definition, Documentation & ERP Control



* Create, approve, and maintain accurate Bills of Materials (BOMs), routings, cycle times, and tooling requirements for all busbar products.


* Oversee sheet layouts, CNC programs, machining fixtures, press tooling, brazing fixtures, gages, and associated process documents.


* Ensure revision control and documentation accuracy within ERP systems.

New Product Introduction (NPI) Leadership



* Drive NPI from concept to production release, providing front-end DFM to optimize manufacturability, repeatability, and cost.


* Ensure timely completion of design reviews, tooling quotations, process documentation, and production validation.


* Coordinate cross-functional engineering activities to meet customer specs and internal capability.

Production Support & Problem Resolution



* Provide sustaining manufacturing engineering support after NPI release; monitor and resolve issues across processes (punching, forming, lamination, assembly, etc.).


* Lead root cause analysis for recurring defects, production escapes, customer returns, and field issues; determine whether issues stem from process variation, tooling wear, operator practice, material/supplier defects, or design.


* Support investigations into dimensional, mechanical, and fit/function issues and implement corrective actions.

Tooling & Continuous Improvement



* Establish tooling quotations and approve tooling, fixtures, and gages for new products, revisions, and process improvements.


* Oversee tool inventory, repair prioritization, and red-tag resolution.


* Drive CI initiatives to improve throughput, repeatability, safety, quality, and reduce cost.

Leadership & Team Development



* Lead the Manufacturing Engineering and Tooling teams-hiring, performance management, mentoring, and technical development.


* Prioritize and clarify engineering projects to ensure on-time delivery and alignment with business objectives.
