Full Job Description
Who We Are Looking For:

Phoenix Tailings is looking for a Principal R&D Scientist to drive the development of new ligand systems and synthetic chemistry platforms that improve the recovery, separation, and production of critical metals. This role will directly shape the chemistry behind Phoenix Tailings' clean metals technology, helping turn advanced molecular design into scalable processes that power the technologies of today and tomorrow.

Key Responsibilities:

  • Design and synthesize novel ligands, extractants, and functional molecules for selective recovery and purification of rare earth elements and critical metals.
  • Develop structure-property relationships that connect ligand design, metal selectivity, extraction performance, stability, and process compatibility.
  • Build and optimize synthetic routes for target molecules with a focus on yield, purity, reproducibility, safety, and scalability.
  • Evaluate ligand-metal interactions, extraction efficiency, kinetics, degradation behavior, and performance under process-relevant conditions.
  • Use analytical and characterization tools to confirm compound identity, purity, reaction outcomes, and metal separation performance.
  • Translate laboratory chemistry into practical process inputs that improve Phoenix Tailings' clean metals production platform.
  • Generate technical reports, experimental plans, data packages, and recommendations that guide R&D and technology development decisions.
  • Identify new molecular design strategies that expand Phoenix Tailings' capabilities in rare earth and critical metals production.


Qualifications:

  • PhD in Chemistry, Organic Chemistry, Organometallic Chemistry, Inorganic Chemistry, Materials Chemistry, or a related field.
  • 5-10+ years of experience in ligand design, synthetic chemistry, separations chemistry, hydrometallurgy, extractive metallurgy, or applied chemical R&D.
  • Hands-on experience designing, synthesizing, purifying, and characterizing organic, inorganic, organometallic, or coordination chemistry systems.
  • Strong understanding of metal-ligand binding behavior, selectivity tuning, structure-property relationships, and chemical performance optimization.
  • Proficiency with analytical and characterization techniques such as NMR, LC-MS, GC-MS, HPLC, FTIR, UV-Vis, ICP-OES/MS, or related tools.


We offer a competitive compensation package that is based on expertise. We also offer the following benefits:

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.
