About the Role

Gravitics is looking for a Buyer/Material Specialist to support the procurement and material planning needs of our mechanical and structural hardware supply chain.

About You

You will own the procurement lifecycle from issuing the purchase order through material receipt, proactively mitigating supply chain risks to maintain uninterrupted production schedules.
