Supply Chain Planner & Purchasing

At RPS, we’re solar-powered and people-powered! Every pump that leaves our warehouse means one less generator or power line—and cleaner, safer access to water. It supports healthier animals, plants, and people while boosting the resilience, independence, and self-sufficiency of rural families and communities.

We’re mission-driven, impact-focused, and yes—we’re as cool as it sounds. We help folks across the country pump water sustainably, from off-grid ranches to remote homesteads. We're a team of tinkerers, builders, customer champions, and adventurers who take pride in solving real-world problems with clean technology. No corporate fluff, just honest work that matters.

This is a high-impact, hands‑on Supply Chain Planner & Purchasing role responsible for owning our end-to‑end supply chain process—from demand and supply planning through purchase order management, vendor coordination, and final receipt at our warehouse. Your decisions directly shape product availability, inventory health, and customer satisfaction in a small company environment.

You will actively manage forecasting, maintain the supply plan, create and track purchase orders, monitor vendor performance, and proactively flag inventory risks before they impact production, open orders, or customer commitments.

• Own the demand planning process: analyze historical sales data, seasonal trends, promotions, and market signals to generate accurate SKU level forecasts.
• Build and maintain rolling supply plans that align purchasing decisions with forecasted demand, target inventory levels, and lead times.
• Track purchasing spend, cost changes, freight impact, and vendor pricing issues to inform inventory and cash decisions.
• Identify demand/supply imbalances early and develop mitigation strategies (expediting, deferrals, substitutions).
• Collaborate with Sales, Marketing, and Operations to incorporate pipeline visibility and promotional lift into the demand plan.
• Track forecast accuracy and bias and continuously refine planning assumptions and methodology.
• Maintain optimal stock levels by SKU based on variability, lead time, and service level targets.
• Identify when system outputs, spreadsheet logic, or planning recommendations do not match operational reality and escalate issues for correction.

• Navigate technical purchasing of products, components, and parts, ensuring accuracy on specs, quantities, compatibility, and quality expectations.
• Generate and issue purchase orders based on approved supply plans and reorder triggers, owning each PO through vendor confirmation, shipment tracking, delivery, and receipt.
• Ensure recurring product, packaging, fulfillment, and customer service feedback is captured and incorporated into future supplier orders and specifications.
• Manage vendor relationships day‑to‑day: confirm order acknowledgments, track lead times, and proactively escape delays.
• Negotiate delivery schedules and resolve discrepancies in pricing, quantities, or shipping documents.
• Maintain accurate vendor master data including MOQs, lead times, pricing, and contact information, and echo PO and vendor risks early with clear options, timing, and business impact.
• Work with international suppliers across time zones.
• Support import documentation, tariff classification, and customs follow up in partnership with leadership, vendors, and freight partners.

• Track inbound shipments from origin to warehouse arrival, coordinating with freight forwarders and carriers as needed.
• Prepare advance shipping notices and receiving documentation for the warehouse team.
• Support timely and accurate goods receipt in the inventory system upon warehouse arrival.
• Investigate and resolve inbound discrepancies (shortages, damages, mislabeled items).

• Support cycle counts and physical inventory reconciliation.
• Maintain clean and accurate data across planning tools and system.
