Sourcing Manager – Ag & Chemical Inputs

Huma•Gilbert, AZ

About The Position

Sourcing Manager – Ag & Chemical Inputs HUMA, Inc. | Gilbert, AZ | Full-Time | 4/9s Schedule (Most Fridays Off) ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ READ THIS FIRST This role is not a fit if your background is primarily in aerospace, defense, automotive, electronics, or large-scale manufacturing parts procurement. The materials, vendors, markets, and dynamics are fundamentally different here. This role is a strong fit if you have sourced raw materials, agricultural inputs, fertilizers, micronutrients, or specialty chemicals — and you know what it means when a supplier in India has a 3-month lead time and your busy season starts in 90 days. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ THIS IS A WORKING ROLE — NO TEAM TO MANAGE The internal title is Director of Sourcing & Supply Chain. You will carry that title and that ownership. What you will not have — at least for now — is a team to manage. You are the sourcing and procurement department. One person. No direct reports. You own strategy and execution simultaneously — that means you build the sourcing plan and you also issue the purchase orders. If you are looking for a team to delegate to, this is not that job. If you are a hands-on sourcing professional who knows ag and chemical inputs and wants to own a function at the director level, keep reading. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ABOUT HUMA HUMA is a U.S.-based mining, manufacturing, and novel technology company specializing in humic solutions — products built on humic substances (ancient oxidized carbons) that serve agricultural, environmental, and tech additive markets. We are a growing mid-sized company with operations across Arizona, New Mexico, and Mexico. Learn more at huma.us. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT YOU WILL DO You support multiple sites: a production facility in Gilbert (liquids and solids), a New Mexico mine & processing facility and the R&D lab team. You are the single point of contact for sourcing and procurement across all of them.

Requirements

Hands-on sourcing experience in agricultural inputs, fertilizers, specialty chemicals, or chemical manufacturing — this is not negotiable
You have personally issued POs, negotiated contracts, and managed vendor relationships in an ag or chemical environment

Ability to read commodity indices and use market intelligence to time purchasing decisions
Experience with international supply chains (suppliers in multiple countries with variable lead times)
NetSuite or comparable ERP experience
Comfortable operating without systems doing the thinking for you — you build and own your own tracking
Self-directed, adaptable, and calm under supply chain volatility
High integrity: Choose Integrity | Win-Win-Win | Seek Innovation
Bachelor's degree in business, supply chain, agronomy, chemistry, or related field

Maintain dual-source qualification for all critical raw materials
