Bachelor’s degree in Chemistry, Chemical Engineering, Biochemistry, Biotechnology, or a related scientific field.
Minimum 1 year of laboratory experience (including internships) using standard analytical methods or pharmacopeias (e.g., USP/EP).
Advanced English proficiency.

Nice To Haves

Practical experience operating and documenting within a Good Manufacturing Practices (GMP) or ISO-certified laboratory environment.
Hands-on proficiency with chromatographic instruments (HPLC, GC) and specialized laboratory techniques (Potentiometric Titration, ICP).
Experience assisting with laboratory project management, method validations, or method transfer activities.
Background in CPG, cosmetics, personal care, or pharmaceutical manufacturing environments.

Responsibilities

Conduct routine quantitative and qualitative analysis of raw materials and finished products applying standard analytical methods or pharmacopeias (USP, EP); provide actionable data to Product Development and Manufacturing teams.
Operate, calibrate, qualify, and troubleshoot core laboratory equipment (e.g., HPLC, GC, Potentiometric Titration, ICP); ensure all instruments are maintained safely according to GMP guidelines.
Support analytical method development, optimization, and validation; assist in transferring analytical methods to global manufacturing sites and train local lab personnel.
Maintain precise, up-to-date laboratory notebooks and documentation following global compliance standards, local EOHS regulations, and Quality systems.
Summarize analytical findings, present data to internal cross-functional partners, and document key learnings to drive continuous laboratory improvements.
