• Proficiency in Microsoft Office (Excel, Outlook, Word) and purchasing or ERP software. 

• Strong organizational skills with high attention to detail. 

• Ability to manage multiple priorities in a fast-paced, project-driven environment.

• May require occasional site visits to understand material needs and logistics. 

• Fast-paced environment driven by construction project timelines and deadlines. 

• Standard business hours with occasional extended hours depending on project demands.
