About The Position

This position develops and maintains the production plan for the High Frequency Modules (HFM) product family. The Master Planner translates validated demand and current ERP/MRP planning recommendations into executable production run plans, quantities, schedules, and projected product availability while balancing material, capacity, and customer requirements. The role collaborates with Supply Chain, Manufacturing Control, Plant/Line Management, Engineering, Quality, Marketing/Sales, and other stakeholders to maintain schedule integrity, drive material readiness, communicate risks, and align production plans with stocking objectives and customer commitments. The position performs current planning and scheduling activities in MAPICS / IBM i and approved planning tools, and supports process design, data validation, testing, training, cutover readiness, and adoption for the future SAP transition. Following SAP go-live, the role will use applicable future-state SAP planning functionality. The listed duties are not comprehensive, and additional tasks within the scope of the position may be assigned. The position requires compliance with corporate safety initiatives and the Company’s Code of Conduct.

Hands-on SAP experience directly relevant to manufacturing production planning and scheduling is required, ideally including SAP S/4HANA PP, MRP, planned and production orders, work centers, routings, material availability, capacity planning/evaluation, exception management, and production scheduling.
Ability to work effectively in the current MAPICS / IBM i environment while supporting the future transition to SAP.
Ability to translate demand, inventory, lead-time, and capacity information into an executable production plan.
Strong analytical and scheduling skills, including proficiency with Excel and Gantt-style planning tools.
Strong cross-functional communication, follow-up, prioritization, and escalation skills.
Ability to manage changing priorities and maintain schedule integrity across multiple products and work centers.

Nice To Haves

Bachelor’s degree in Supply Chain Management, Operations Management, Industrial Engineering, Business Administration, or a related field; equivalent manufacturing planning experience may be considered.
Three or more years of production planning, master scheduling, manufacturing control, supply planning, or related experience in a manufacturing environment.
MAPICS / IBM i, Infor XA, or comparable legacy ERP experience.
Experience in electronics, RF/microwave, high-mix manufacturing, or regulated manufacturing environments.

Responsibilities

Review MAPICS / IBM i MRP and planning recommendations alongside validated demand to determine appropriate HFM production run quantities and timing.
Use production runs released by Production Control as the basis for forward-looking planning, scheduling, sequencing, material-readiness reviews, capacity evaluations, and projected availability dates.
Develop, maintain, and communicate the HFM master production schedule with Plant/Line Management and Manufacturing Control.
Establish production lot sizes and timing based on material availability, routings, test requirements, capacity, and business priorities.
Maintain product-availability schedules, including Gantt charts or equivalent tools, to forecast completion and stock availability dates.
Evaluate schedule feasibility against capacity, material, test, and operational constraints; adjust plans as conditions change.
Support scenario planning for changes in demand, customer requirements, capacity, lead time, or production risk.
Translate production plans into material requirement timing and communicate priorities to Supply Chain.
Monitor material readiness and coordinate follow-up on shortages or late commitments that threaten the schedule.
Work with Supply Chain on recovery plans for constrained material while preserving Supply Chain’s ownership of raw-material inventory strategy.
Coordinate with Supply Chain and, when required, engage suppliers to clarify timing, expedite critical requirements, or protect customer commitments.
Identify recurring material risks and support improvements to planning parameters, lead times, stocking assumptions, or replenishment strategies.
Maintain projected availability dates for stocked products, customer orders, new product requirements, and special or spike demand.
Incorporate validated demand changes, forecast updates, new product release timing, and special customer requirements into production plans.
Communicate schedule risks, changes, and recovery plans to Manufacturing Control and relevant stakeholders in a timely manner.
Align planned production quantities and timing with approved stocking targets and demand signals.
Partner with Plant/Line Management to confirm schedule feasibility while leaving production-floor execution ownership within Manufacturing.
Coordinate with Manufacturing Control on execution risks, late runs, shortages, holds, and other exceptions affecting the master schedule.
Work with Engineering on new product release timing and manufacturability inputs affecting planned production.
Coordinate with Demand Planning and Marketing/Sales on validated demand changes, special orders, and expected demand spikes.
Facilitate periodic schedule reviews and escalate decisions requiring changes to priorities, capacity, or customer commitments.
Perform current production planning and scheduling in MAPICS / IBM i and approved planning tools; support the future SAP transition through process design, data validation, testing, training, cutover readiness, and adoption.
Review planning exceptions and recommended actions from current systems and determine the appropriate planning response; perform this responsibility in future-state SAP functionality after go-live.
Identify planning master-data issues involving lead times, lot sizes, planning parameters, routings, or other data affecting schedule quality.
Participate in continuous improvement activities to improve planning accuracy, schedule adherence, product availability, and stocking performance.
Comply with and support corporate safety initiatives and abide by the Company’s Code of Conduct.
