Fiber Chemicals Specialist Chemist

More About This Role

What you need to know about this position:

• Bachelor’s degree in Chemistry or Chemical Engineering (Masters or PhD in Polymer Chemistry, Material Science, or Textile Chemistry is highly preferred).
• Minimum of 5 years of experience in spin finish and sizing chemicals specifically within synthetic fiber (PAN, Nylon, Polyester) production processes, able to quantify results, leading projects, improvement activities.
• Deep understanding of surface chemistry, colloid chemistry, and emulsion technologies.
• Possess hands‑on analytical equipment capabilities (GC, HPLC, FTIR, Rheometer, XPS, AFM, etc.) along with wet chemistry experience.
• Strong ability to implement Design of Experiments (DoE) and statistical data analysis (e.g., Minitab), proficiency in MS Office applications, and solid knowledge of ERP tools.
• Problem‑solving oriented, innovative mindset, high laboratory discipline, and a strong penchant for teamwork.
• Advanced proficiency in English to follow technical literature and communicate with global stakeholders.
• Reside in or be willing to relocate to Yalova, İzmit, or the Anatolian side of Istanbul.

• Primarily responsible for developing, formulating and enhancing precursor finishes (spin‑finish) and carbon fiber sizing chemicals used in production lines.
• Conduct chemical modification studies to improve interfacial adhesion between carbon fibers and various polymer matrices (epoxy, vinyl ester, thermoplastics, etc.).
• Test the applicability of developed chemicals on pilot and mass production lines; optimize parameters such as drying, polymerization, and coating thickness.
• Characterize the thermal stability, friction coefficient, and mechanical properties (tensile strength, ILSS) of the fiber after chemical coating.
• Stay updated on global literature and raw material markets regarding next‑generation sustainable surfactants, emulsifiers, and film‑forming polymers.
• Support energy, infrastructure, and automotive‑related carbon fiber and composite product development projects as a team member, working with multiple functions in the field.
• Provide and maintain detailed documentation and procedures for all work performed.
