Avionics Material Planner

Relativity Space•Long Beach, CA

18d•$100,800 - $151,200

About The Position

As an Avionics Material Planner, you will own material planning for Terran R avionics hardware, including flight computers, power distribution units, sensor and data acquisition boxes, and other line-replaceable units. You will support products from development and qualification builds through flight production and into rate, often while designs are still evolving. The role covers end-to-end material planning for avionics assemblies, from electronic components, connectors, bare boards, wire, and cable through PCB assemblies, wire harnesses, and box-level integration hardware. You will collaborate across engineering, sourcing, manufacturing, integration, test, and launch teams; identify and manage material risks; assess the effects of engineering changes; coordinate material flow to suppliers; and develop forecasts and planning processes to support production and improve MRP automation and accuracy in the ERP platform.

Requirements

At least 4 years of experience in material planning, demand planning, or production planning.
Direct experience planning avionics or high-reliability electronics hardware in the aerospace, defense, or space industry, such as electronic components, PCB assemblies, wire harnesses, or electromechanical box-level assemblies.
Experience supporting products from NPI or development into production, including planning against changing bills of materials and managing engineering-change impacts across multiple builds.
Working knowledge of electronics supply chain dynamics, including component lead times and allocation, obsolescence, minimum order quantities and reels, contract manufacturer kitting, and part substitutions or alternates.
Strong understanding of MRP inputs and how MRP functions within ERP systems such as Plex, Infor LN, SAP, or Oracle.

Nice To Haves

Familiarity with space-grade or high-reliability part requirements, such as lot and date code control, traceability, screening, and counterfeit prevention.
Experience with design release processes and PLM systems, and how they feed ERP.
Experience with data analysis tools such as SQL, Tableau, or advanced Excel.

Responsibilities

Own end-to-end material planning for avionics assemblies, from electronic components, connectors, bare boards, wire, and cable through PCB assemblies, wire harnesses, and box-level integration hardware.
Work with Avionics Engineering, Sourcing, Manufacturing, Integration, Test, and Launch teams to derive material demand from multi-level bills of materials and build schedules, influencing cross-functional decisions without direct authority.
Identify long-lead and high-risk items ahead of formal design release using preliminary bills of materials and engineering input; recommend risk buys, early material authorizations, and buffer strategies, and explain tradeoffs when data is incomplete.
Assess the material impact of engineering changes and part revisions, including obsolescence, excess exposure, rework or scrap decisions, and effectivity across builds.
Manage material flow to contract manufacturers and harness suppliers, including consigned and turnkey kitting, shortage tracking, allocation of constrained components, and clear-to-build readiness.
Run the build-by-build Material Readiness process under tight deadlines.
Develop avionics material forecasts and planning processes that inform Sourcing strategy, support the transition from NPI to production, and improve MRP automation and accuracy in the ERP platform.
