Senior Manufacturing Manager

Job description

Renesas is looking for an experienced Senior Manufacturing Manager to lead front-line manufacturing operations at our Penang site, one of Renesas' key back-end assembly and test facilities supporting automotive, industrial, and IoT semiconductor products. This role is responsible for day-to-day production performance across multiple shifts and manufacturing lines, while driving operational excellence, capacity, and workforce strategies that keep the site competitive in a fast-moving semiconductor market.

The Senior Manufacturing Manager is a critical link between the shop floor and site leadership, translating corporate operational goals into executable floor-level plans and escalating systemic issues that need cross-functional or leadership attention.

Key Responsibilities

Own end-to-end manufacturing performance for assigned production lines, including output, yield, cycle time, cost per unit, and on-time delivery targets. Lead a multi-shift team of production supervisors, engineers, and technicians (typically 500+ headcount), building bench strength and succession depth. Drive continuous improvement using Lean Manufacturing, Six Sigma, and Total Productive Maintenance (TPM) methodologies to reduce cost, scrap, and downtime.

Partner with Process Engineering, Quality, and Equipment Engineering to resolve yield excursions and equipment-related bottlenecks. Manage capacity planning and production scheduling in coordination with Supply Chain and Planning teams to meet customer demand commitments. Champion EHS (Environment, Health & Safety) compliance and drive a zero-incident safety culture on the floor. Own the manufacturing operating budget for assigned lines, including labor, materials, and overhead cost control.

Lead new product introduction (NPI) and technology transfer activities from a manufacturing readiness standpoint. Report site-level KPIs (yield, OEE, safety, cost, delivery) to senior leadership and drive corrective actions for gaps. Build and sustain a high-performance culture through coaching, structured problem-solving (e.g., 8D, DMAIC), and employee engagement initiatives.

Qualifications

Bachelor's degree in Electrical/Electronic Engineering, Industrial Engineering, Manufacturing Engineering, or a related technical field. Master's degree or MBA is a plus. 10+ years of progressive manufacturing experience in a semiconductor, electronics, or precision manufacturing environment, with at least 3-5 years in a managerial capacity leading multi-shift operations. Strong working knowledge of semiconductor back-end processes (assembly, test, and/or wafer fab operations, depending on site scope).

Demonstrated success driving Lean/Six Sigma initiatives with measurable cost, yield, or throughput improvements. Experience managing P&L or cost-center budgets for a manufacturing unit. Solid understanding of EHS regulatory requirements and quality systems (ISO 9001, IATF 16949, or equivalent). Proven people-leadership track record in hiring, developing, and retaining engineering and production talent.

Preferred Skills

Experience with automotive-grade semiconductor manufacturing standards (ISO 9001, IATF 16949, PPAP, APQP). Familiarity with MES, SAP, or other manufacturing execution/ERP systems. Six Sigma Black Belt or Lean certification. Experience leading site-level digital transformation or Industry 4.0 initiatives. Prior experience in a global, matrixed organization coordinating with regional or corporate stakeholders.
