About The Position

Relativity Space is seeking a Material Planner to join their Supply Chain team. This role is crucial for turning design intent into executable reality by managing lead time, cost, complexity, and manufacturability for the Terran R vehicle. The Material Planner will be responsible for driving the material demand planning process across multiple vehicle missions and programs. This involves working cross-functionally to maintain real-time visibility into material supply sources, manage material requirements, and ensure seamless material acquisition and delivery. The ideal candidate is proactive, detail-oriented, possesses a deep understanding of supply chain processes, and can thrive in a fast-paced, high-pressure environment.

Requirements

Minimum of 5 years of experience in material planning, demand planning, fulfillment planning, or similar roles in fast-paced manufacturing, aerospace, or supply chain environments.
Experience working cross-functionally with internal stakeholders such as engineering, manufacturing, procurement, supply chain, finance, accounting, quality, and executive management.
Strong understanding of Materials Requirements Planning (MRP), including key inputs (e.g., material attributes, demand, supply) and how MRP functions within ERP systems like Infor LN, SAP, or Oracle.
Experience creating and managing demand forecasts and incorporating necessary data inputs for accurate material planning.
Familiarity with BOM (Bill of Materials) reconciliation.
Ability to work under tight deadlines and prioritize tasks in a fast-paced environment.
Knowledge of data analysis tools such as SQL, Tableau, or advanced Excel techniques.
Experience with New Product Development (NPD) or New Product Introduction (NPI).
Experience with design release processes and systems.

Nice To Haves

Background in aerospace start ups or frontier technology industries.

Responsibilities

Partner with Sourcing/Procurement, Engineering, Manufacturing, Integration, Test, and Launch teams to derive material demand from complex multi-level Bills of Materials (BOMs) and schedules, driving material requirement plans and priorities across multiple vehicle missions and programs.
Generate material requirement signals and collaborate with Procurement to develop actionable material acquisition strategies.
Manage the mission-by-mission 'Material Readiness' process, providing real-time visibility into material supply and demand while ensuring alignment between Engineering, Supply Chain, Manufacturing, Test, and Launch teams.
Develop and implement material allocation strategies/models for constrained or at-risk materials based on company priorities and supply conditions.
Quantify material forecasts that inform Sourcing’s immediate and medium-term material acquisition strategies, ensuring the smooth flow of materials through the production lifecycle.
Participate in the development of Materials Requirements Planning (MRP) systems and processes within ERP platforms, increasing automation and accuracy in end-to-end planning operations.
