About The Position

At American Transmission Company (ATC), every project we deliver helps power homes, businesses, and communities across our region. Behind those projects are smart sourcing decisions, trusted supplier relationships, and strategic procurement professionals who help ensure we have the right partners, materials, and services at the right time. We're looking for a Category Buyer who can bring strategic thinking, strong business acumen, and a passion for continuous improvement to our Supply Chain team. This is an opportunity to influence critical infrastructure projects, shape supplier strategies, drive measurable business value, and collaborate with stakeholders across the organization. If you're energized by solving complex challenges, negotiating successful outcomes, and building partnerships that make an impact, we'd like to meet you.
