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.

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.
Day-to-day sourcing:
– Monitor daily requisitions across sites and issue purchase orders through NetSuite
– Get price quotes, compare against commodity indices, and negotiate when pricing or lead times are off
– Manage inbound freight — negotiate with suppliers or source independently depending on rate
– Purchase chemicals, reactants, and lab supplies for the R&D team
– Support the New Mexico mining operation with parts, equipment, and capital expense sourcing
Supplier management:
– Maintain dual-source qualification for all critical raw materials
– Run a multi-step new supplier qualification process: validation, sampling, R&D testing, regulatory compliance, pricing negotiation
– Attend industry events (fertilizer/ag-chem conferences); maintain active relationships with key suppliers
– Monitor commodity indices and market intelligence to get ahead of price movements
Demand planning and inventory:
– Run quarterly horizon planning using 2 years of order history — materials come from Canada, Mexico, China, and India etc with lead times up to 3+ months
– Set per-material calendar checkpoints and communicate proactively with production on constraints
– Plan around seasonal demand and supplier shutdown windows (holidays, summer maintenance)
– Track inventory levels and balance working capital against stockout risk

WHAT YOU BRING
Required:
– 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
– Strong lead time awareness — you manage horizons, not just open orders
– 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
Highly preferred (say so clearly in your application):
– Direct experience sourcing humic substances, micronutrients, potassium, calcium, or nitrogen-based inputs
– Familiarity with regulatory compliance requirements for ag-chem raw material switching
– Experience supporting multi-site procurement as a team of one
– History of building or running a formal supplier qualification process

– Quarterly discretionary bonuses
– Medical, dental, vision, and life insurance
– 401(k) with up to 6% company match
