What are the responsibilities and job description for the Sourcing Manager – Ag & Chemical Inputs position at Huma?
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.

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
- 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
- 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
Required
WHAT YOU BRING

- 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

- High integrity: Choose Integrity | Win-Win-Win | Seek Innovation

- Direct experience sourcing humic substances, micronutrients, potassium, calcium, or nitrogen-based inputs
