Commodity Manager, Mechanical Commodities

Overview

Tonal's Commodity Manager for Mechanical Commodities owns the largest tooled spend in our bill of materials: fabricated metal, metal assembly, injection molding, finishing, and hardware. Tonal buys finished assemblies from our contract manufacturer in Guadalajara, but we direct this supply base ourselves — you select the suppliers, negotiate the price, own the tooling, and hand our CM a directed price to buy at.

The travel expectation for this role is 20-30%.

What You Will Do

Develop and execute the global category strategy for fabricated metal (stamping, machining, tube bending, weldments, extrusion, casting), metal assembly, injection molding, finishing and coatings, and fasteners and hardware

Own Tonal's supplier strategy for the category: identify candidates, build the landed-cost business case, qualify the supplier, and manage the transfer

Lead supplier selection and qualification across North America and Asia, and manage ongoing supplier performance through scorecards and business reviews; own the approved vendor list recommendation jointly with Manufacturing Quality

Negotiate piece price, tooling and NRE, long-term agreements and payment terms to the lowest total cost of ownership, and maintain a rolling cost-down roadmap

Build should-cost models from first principles — material weight against index, press or cycle time, cavitation, secondary operations, labor rate, overhead and margin — and negotiate against them

Structure and manage index-based pricing for steel, aluminum and resin so that cost moves with the market in both directions

Own tooling as an asset: a complete register of Tonal-owned tools, capacity per tool, cavitation and press-size decisions, second-tool and refurbishment triggers, and the capital plan behind them

Partner with Mechanical Engineering on DFM, tolerance and finish specifications, and material selection, bringing supply and cost reality into design reviews

Carry dual-source and region coverage for the top 80% of category spend, with a tooling strategy that makes a second source real rather than theoretical

Work with our contract manufacturer's metal fabrication and assembly operations in Guadalajara on capacity, yield, scrap and process cost

Direct our contract manufacturer's purchasing to your negotiated prices, and support the quarterly quoted-versus-paid BOM audit

Support qualification with Manufacturing Quality: APQP, PPAP, FAI and tool sign-off

Support new product introduction through quoting, tool development timelines and material availability through ramp

Partner with trade compliance on regional content and duty, including USMCA qualification of localized parts

Who You Are

Bachelor's degree in mechanical or manufacturing engineering, business, or a related field

7–10 years of commodity management or sourcing experience covering fabricated metal and/or plastics, at a hardware product company or a contract manufacturer

Deep process knowledge in at least two of: stamping and die tooling, CNC machining, tube fabrication and welding, injection molding and mold tooling, or finishing and coatings

Demonstrated ownership of a tooling portfolio — tool builds, capital approvals, capacity and cavitation decisions, and tool transfers between suppliers

Proven ability to build a bottom-up should-cost model and negotiate against it, including index-linked pricing structures
