Production Planner

About the Role

We are looking for a proactive and detail-oriented Production Planner to support Lumentum's global high-precision manufacturing environment. This role is responsible for developing build plans, ensuring material readiness, coordinating cross-functional execution, and driving disciplined planning for mass production, engineering builds, and production ramp activities. The Production Planner ensures on-time build delivery, stable production flow, and strong communication across global planning, operations, engineering, supply chain, and program management teams.

Responsibilities

• Develop and maintain detailed production schedules for mass production builds, engineering builds, pilot runs, and production ramp activities.
• Translate engineering and program requirements into feasible build plans aligned with capacity, materials, and operational priorities.
• Review MRP requirements, validate demand signals, and ensure timely availability of materials and ramp builds.
• Coordinate with Buyers, Global Supply Chain, and suppliers to secure material commitments, expedite shortages, and resolve supply gaps.
• Lead build readiness reviews (BRR) and ensure all prerequisites—materials, tooling, test capacity, documentation, ECO releases—are in place before build execution.
• Track daily build progress, monitor WIP status, and address risks or delays with timely communication to stakeholders.
• Support production ramp readiness by validating equipment capacity, manpower, test capability, and supporting resources.
• Identify constraints across supply, capacity, or process flow and coordinate recovery plans to ensure on-time delivery.
• Maintain accurate planning parameters (lead time, safety stock, lot size, planning attributes) to support effective MRP and planning accuracy.
• Generate build status reports, schedule adherence metrics, and material readiness summaries for local and global stakeholders.
• Drive continuous improvement in planning processes, communication, data discipline, and operational coordination.
• Ensure compliance with Lumentum's planning standards, governance, build control processes, and documentation requirements.

Qualifications

• Bachelor's degree in Supply Chain, Industrial Engineering, Manufacturing, Business Administration, or a related field.
• At least 5 years of experience in production planning, NPI planning, material planning, or supply chain roles within high-tech manufacturing.
• Strong working knowledge of MRP/ERP systems (Oracle preferred), BOM structures, and ECO/change management processes.
• Experience supporting NPI or Mass Production builds, engineering builds, and ramp-to volume transitions in a global manufacturing environment.
• Strong analytical skills with the ability to interpret data, identify risks early, and propose effective mitigation actions.
• Excellent communication and coordination skills, with the ability to work with cross functional and cross-site teams.
• High attention to detail, strong organizational skills, and the ability to manage multiple priorities in a fast-paced environment.
• Proficiency in Microsoft Excel for analysis and reporting; experience with planning dashboards or analytics tools is a plus.
• Ability to work independently while maintaining strong collaboration with global partners.
