Material Planner

About the Team:

The Supply Chain team turns design intent into executable reality, balancing lead time, cost, complexity, and manufacturability to ensure we can build and scale Terran R. On this team, you're not just placing orders; you're actively shaping the solution. With full ownership across raw materials, capital equipment, and services, the role requires both strategic thinking and day-to-day execution. As the company scales, supply chain becomes increasingly central, working closely with engineering, quality, manufacturing, and more to make decisions that work for today but also for tomorrow. This is a team for those who want to operate at the intersection of technical ambition and business execution, driving tangible progress to keep the Terran R program on track.

About the Role:

As a Material Program Manager at Relativity Space, you will play a key role in driving the material demand planning process across multiple vehicle missions and programs. You will work cross-functionally to maintain real-time visibility into material supply sources, manage material requirements, and collaborate with internal teams to ensure seamless material acquisition and delivery. The role requires a proactive individual who is detail-oriented, has a deep understanding of supply chain processes, and is capable of thriving in a fast-paced, high-pressure environment.

• Material Demand Planning: 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. This will help drive material requirement plans and priorities across multiple vehicle missions and programs.
• Material Requirements Signals: Generate material requirement signals and collaborate with Procurement to develop actionable material acquisition strategies.
• Material Readiness Process: 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.
• Material Allocation Strategy: Develop and implement material allocation strategies/models for constrained or at-risk materials based on company priorities and supply conditions.
• Material Forecasting: Quantify material forecasts that inform Sourcing's immediate and medium-term material acquisition strategies, ensuring the smooth flow of materials through the production lifecycle.
• MRP Systems Development: 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.

About You:

• Minimum of 2 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.

Nice to haves but not required:

• 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.
• Background in aerospace, frontier technology industries, or manufacturing environments.
