At Slate, we've got one job: building a vehicle you'll fall in love with, right here in the USA. We believe that car buyers-not car companies-should call the shots. We like looking at a road, not a screen.

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.

You and the team will do this through forecasting demand (sales planning), optimizing inventory levels, and aligning procurement and production activities to meet customer requirements and business objectives. You will bring SI&OP to life across the business units of Slate, including vehicle (consumer and fleet), service parts, accessories, and apparel and merch. You will work cross-functionally with Sales, Marketing, Brand, Engineering, Purchasing, Production, Finance, and other business units to develop a rolling 12 -24 month executable business plan.

WHAT YOU GET TO DO

  • Ability to create, manage, and train team members in advanced forecasting and modeling, leveraging AI, machine learning, and predictive analytics to improve demand sensing and supply planning.

  • Develop accurate demand forecasts (including developing forecast models) from the data gathered, including documenting adjustments based on data gathered to determine accuracy of data gathered

  • Develop accurate demand forecasts (including developing forecast models) from the data gathered, including documenting adjustments based on data gathered to determine accuracy of data gathered.

  • Measure and evaluate forecast accuracy at multiple lag times to further improve the forecasting process.

  • Monitor inventory levels to ensure alignment with demand forecasts and to drive appropriate operational planning.

  • Work with procurement, production, and fulfillment teams to ensure appropriate inventory levels to meet customer demand while minimizing excess and obsolete stock.

  • Work with procurement, production, sales, and other teams to resolve imbalances between Demand, Inventory, and Operations plans, including providing insights to help lead to the most effective and efficient issue resolution.

  • Develop, track, and report key performance indicators (KPIs) related to SI&OP, including but not limited to, forecast accuracy (at multiple time lags), inventory turns, service levels, and production / procurement performance.

  • Support the monthly SI&OP cycle through preparation and execution of the monthly SI&OP cycle, including but not limited to, meeting presentation preparation, analysis to support SI&OP recommendations, and SI&OP KPI report outs.

WHAT YOU BRING TO THE TEAM

  • Bachelor’s degree in Business Administration, Supply Chain Management, Operations, Finance, Data Analytics or equivalent is preferred. While a degree is preferred, we value hands-on experience and a proven track record of success as a suitable substitute and encourage candidates to apply who can demonstrate relevant and commensurate professional experience.

  • 8+ years of experience in Supply Chain, Logistics, or Business Management, preferably working within SI&OP or Demand Planning.

  • A proactive, “one company” teammate with a continuous improvement approach, equally comfortable with warehousing practices, material management, business planning, and financial implications.

  • Capability to work cross-functionally with external partners and internal teams, building strong relationships that produce positive results.
