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.

  • Deep knowledge of small-to-large tonnage injection molding processes and tooling cost structures.
  • Experience managing or establishing direct resin procurement strategies.
  • Ability to quickly identify cost drivers in injection-molded parts, including tooling, materials, processing, and supplier margins.
  • Proven experience negotiating commercial agreements and supplier contracts.
  • Strong analytical and problem-solving skills with the ability to support cost modeling and supplier benchmarking.
