About Slate

At Slate, we’re building safe, reliable vehicles that people can afford, personalize and love—and doing it here in the USA as part of our commitment to reindustrialization. The spirit of DIY and customization runs throughout every element of a Slate, because people should have control over how their trucks look, feel, and represent them.

Slate is looking for an energetic, organized, and experienced 3PL Partner Manager to join our growing team.

Reporting directly to the Sales Operations Lead, you are customer‑led in everything that you do.

Your primary responsibility is to lead all aspects of our relationship with our 3PL while maintaining tracking of inventory ordered for and located at the 3PL. You will work directly with our 3PL on developing the interactions between Slate and the 3PL, driving process and system improvement to meet and beat our SLA (Service Level Agreements) with our customers while maintaining appropriate inventory levels of shipping supplies and products.
