ElDorado National California Inc•Riverside, CA

4d•$95,000 - $110,000

About The Position

We are seeking a highly analytical and execution-oriented Master Scheduler to serve as the planning leader for our manufacturing operations. This role goes beyond running MRP or managing materials; it owns end-to-end production planning and scheduling, drives SIOP execution, and establishes the data discipline required to support a successful ERP environment. The ideal candidate will lead the planning side of our ERP, connect demand to capacity and materials, own the Clear-to-Build process, and translate the master schedule into work center- and station-level execution on the production floor. This role operates cross-functionally across Sales, Engineering, Supply Chain, and Production, ensuring alignment to a single, executable plan in a dynamic, restart and scale-up manufacturing environment.

Requirements

Deep understanding of production planning, master scheduling, and SIOP in a manufacturing environment.
Strong knowledge of ERP systems (SAP, Oracle, JD Edwards, or similar), including planning master data and scheduling logic.
Understanding of low-volume, high-mix manufacturing environments.
Familiarity with capacity planning, constraint management, and manufacturing execution workflows.
Knowledge of automotive OEM manufacturing standards and production processes.
Proven ability to lead planning functions, not just execute transactions.
Strong analytical judgment with the confidence to challenge assumptions and commitments using data.
Advanced proficiency in Microsoft Excel (pivot tables, lookups, macros).
Excellent cross-functional communication and stakeholder management skills.
Ability to operate with urgency and clarity in ambiguous, fast-changing environments.
High energy, strong ownership mindset, and bias toward execution.
Bachelor’s degree in Supply Chain, Industrial Engineering, Business, or a related field.
Minimum 5+ years of experience in production planning, master scheduling, or supply chain roles.

Nice To Haves

APICS certification (CPIM, CSCP) strongly preferred.
Experience in automotive OEM manufacturing strongly preferred.
Prior involvement in ERP implementations or major system transitions highly desirable.
Project management experience is a plus.

Responsibilities

Own and manage the master production schedule, aligning demand forecasts, capacity, materials, and operational constraints.
Lead SIOP execution end to end, connecting demand signals to capacity planning and material readiness.
Establish and enforce strong ERP data discipline, including BOMs, routings, lead times, calendars, and planning parameters.
Drive and own the Clear-to-Build process, ensuring schedules released to the floor are executable and supported by material and capacity.
Translate the master schedule into work center- and station-level execution, supporting production flow and floor-level accountability.
Serve as the planning lead for ERP implementation and stabilization, ensuring planning logic supports operational reality.
Partner cross-functionally with Sales, Engineering, Supply Chain, and Production to maintain alignment to a single, integrated plan.
Operate effectively in a restart and scale-up environment, making sound decisions despite imperfect data and shifting priorities.
Perform advanced data analysis to identify bottlenecks, constraints, and risks; proactively recommend and implement corrective actions.
Push back on infeasible commitments using data-driven analysis while balancing customer, operational, and business priorities.
Report key planning and scheduling KPIs to leadership and support continuous improvement initiatives.
Utilize advanced Excel and ERP reporting tools to support scenario planning and decision-making.
