As a Principal Scientist you will serve as a central technical resource supporting the entire global Colgate-Palmolive portfolio by developing and validating state-of-the-art analytical platforms to characterize complex product matrices. Operating within the global R&D organization, you will act as the technical arbiter of "Truth," ensuring that every chemical claim made by Marketing is backed by statistically rigorous, peer-reviewed-quality data. This role offers an exciting opportunity to spearhead Lab 4.0 digital transformations, run advanced competitive teardowns, and defend the company's intellectual property.

Your primary objective will be to provide flawless analytical characterization that guarantees formulation parity, regulatory compliance, and consumer safety across all product categories.

Responsibilities

• Advanced Method Development:
  Designs and validates novel analytical protocols for active and critical inactive ingredients, stabilizers, and sensory molecules using high-resolution LC/GC MS and NMR technologies.
• Crisis Chemistry & Forensic Analysis:
  Leads proactive monitoring and "Rapid Response" forensics for trace contaminants, conducting root-cause analysis on stability failures or manufacturing deviations to ensure safety amid supply chain shifts.
• Deformulation & Competitive Intelligence:
  Conducts competitive product teardowns to break down rival formulations to their base molecules, utilizing non-targeted analysis (NTA) workflows to structurally identify unknown components, and evaluates optimized ingredients from new suppliers to ensure absolute formulation parity.
• Claim Substantiation & Legal Defense:
  Partners with Marketing and Legal teams to transform analytical results into "Visual Science" for claim validation, ensuring all methods meet AOAC, USP, or ISO standards to remain legally unassailable.
• Lab 4.0 & Digital Transformation:
  Evaluates high-throughput tools, oversees the implementation of MS Imaging platforms, and collaborates with Digital R&D to build automated data processing pipelines, feeding mass spec chemo metric and big data into predictive Machine Learning models.
• Sustainable Packaging Interface:
  Develops standardized methodologies including ultra-trace extractables and leachables (E&L) screening to investigate chemical interactions between formulas and new sustainable or recycled packaging materials to ensure zero migration of impurities.

Required Qualifications

• PhD in Analytical, Organic, or Medicinal Chemistry
• 10 years of advanced laboratory experience.
• Expert-level knowledge of High-Resolution LC-MS and GC-MS for content quantification and structure elucidation.
• Technical proficiency in spectroscopic techniques including FTIR, Raman, and NMR as supporting tools for understanding molecular interactions within a formula.
• Proven experience working within a GxP (GLP/GMP) regulated environment with a strong understanding of data "Chain of Custody" protocols.

Preferred Qualifications

• Specialized experience in Microbiome Analytics, including…
