Role Overview
Arbor Energy is seeking a Senior Purchasing Specialist to help build and scale a world-class supplier ecosystem as we transition from early prototypes to production-ready hardware. Reporting directly to the Head of Supply Chain, you will own critical supplier relationships, sourcing initiatives, and purchasing operations that support Arbor's most important development and manufacturing programs.
You will lead complex sourcing efforts across a diverse set of commodities and manufacturing processes while partnering closely with Turbomachinery, Combustion, Systems, Test, and Manufacturing teams. This role requires strong commercial judgment, excellent communication skills, and the ability to navigate technical and operational ambiguity while balancing cost, quality, delivery, and risk.
As a senior member of the Supply Chain organization, you will independently manage major sourcing projects, lead cross-functional initiatives, mentor less experienced team members, and play a key role in developing and implementing the procurement processes, tools, and operating practices needed to support Arbor's growth. You will help transform Supply Chain from a startup function into a scalable and repeatable operation by establishing workflows, improving systems, and driving operational excellence.
This role is central to how Arbor's values show up in our supplier ecosystem, leading with love in how we communicate, stewarding our planet through responsible sourcing, and exploring the uncharted as we build new supply pathways for novel hardware.
This is an onsite opportunity in our El Segundo, CA office.
