Who We Are Looking For

Phoenix Tailings is looking for a Commercial Chief of Staff with a strong track record selling mineral feedstocks, oxides, concentrates, and other mineral-derived materials. You will work closely with executive leadership to shape commercial priorities, develop strategic customer relationships, and convert opportunities into long-term agreements. The ideal candidate brings commercial leadership experience from mining, mineral processing, refining, or metals trading and understands how material composition, processing requirements, and supply reliability influence purchasing decisions. You will combine hands-on deal execution with the commercial discipline needed to scale a domestic critical-metals business.

Key Responsibilities:

  • Translate executive commercial priorities into target accounts, deal strategies, and measurable milestones.
  • Lead commercial opportunities for mineral-derived materials from initial engagement and technical evaluation through negotiation and signed agreements.
  • Build relationships with mining companies, mineral processors, refiners, metals traders, and industrial buyers to develop sales opportunities and strategic supply relationships.
  • Structure and negotiate agreements covering pricing, volume, material specifications, payable content, impurity limits, delivery terms, and supply commitments.
  • Work with technical and operations teams to evaluate customer requirements, coordinate material sampling and qualification, and establish achievable commercial commitments.
  • Assess market demand, benchmark pricing, competing supply sources, and processing economics to prioritize opportunities and recommend commercial terms.
  • Establish pipeline reviews, revenue forecasts, and deal tracking that give executive leadership a clear view of progress, risks, and required decisions.
  • Prepare commercial recommendations and lead follow-through on priority deals, resolving issues involving assays, product acceptance, logistics, and contract terms.
  • Align commercial agreements with production plans and material availability to support reliable delivery and durable customer relationships.

Qualifications:

  • Substantial sales and commercial leadership experience involving mineral feedstocks, oxides, concentrates, or closely related mineral and metallurgical products.
  • A demonstrated record of originating, negotiating, and closing complex materials transactions within mining, mineral processing, refining, or metals trading.
  • Practical understanding of how assays, contained metal value, mineralogy, moisture, impurities, and recovery considerations affect material valuation and customer acceptance.
  • Experience negotiating commercial structures such as offtake agreements, indexed pricing, payability schedules, treatment or refining charges, and impurity penalties.
  • Established relationships with buyers, producers, processors, or trading partners across mineral and metals supply chains.
  • Ability to evaluate deal economics, counterparty reliability, logistics requirements, and supply risk when recommending commercial commitments.
  • Experience building actionable account plans, disciplined sales pipelines, and credible commercial forecasts.
  • Strong commercial judgment and the ability to work directly with executive leadership while personally advancing negotiations and closing deals.

What We Offer:

    This pay range reflects best estimate for the total cash compensation which includes salary + discretionary bonus for this role. Total package  may vary based on experience and qualifications.

    Pay Range: $165,000- $215,000 total cash compensation plus equity
  • Healthcare: 100% Medical, dental, and vision coverage for employee.
  • Stock Options: Ownership in a fast-growing venture-backed company. 
  • Time Off: Unlimited PTO.
