Job description

CircuTex Limited, headquartered in Hong Kong Science Park, is a pioneering green-tech enterprise dedicated to resource circularity and sustainable materials innovation. We specialize in the high-value recycling of textile waste, the synthesis and application of advanced carbon materials (such as graphene), and the development of green construction composites. We are currently seeking a dynamic and hands‑on Postdoctoral Fellow to drive our core laboratory R&D and experimental breakthroughs.

Key Responsibilities

Core Experimentation & Technology Development:

Independently lead or conduct laboratory R&D, formulation optimization, and bench/pilot-scale trials in green technologies, polymer modification, textile upcycling, pyrolysis, or graphene‑enhanced construction composites.

Formulate rigorous experimental designs, oversee material characterization, performance testing, and data analysis to investigate the impact of process parameters on material properties.

Laboratory Infrastructure Management:

Oversee the operation, maintenance, and safety protocols of core R&D equipment, and guide instrument optimization.

Industry‑Academia Technical Collaboration:

Support technical exchanges, experimental synergies, and technology realization with partnered universities and research institutions.

R&D Support for Commercialization:

Provide critical empirical data and scientific insights to support technical feasibility evaluations.

Requirements

Educational Background:

Ph.D. degree in Chemistry, Chemical Engineering, Materials Science and Engineering, Polymer Materials, Environmental Engineering, Civil Engineering, or related disciplines.

Research & Hands-on Skills:

Strong experimental background with a proven track record of independent problem‑solving in a laboratory setting; familiar with material characterization and analytical techniques.

Hands‑on experience in waste recycling, polymer blending, graphene application, or green building materials is highly preferred.

Rigorous, detail‑oriented, and highly capable of troubleshooting technical challenges in experiments.

Strong teamwork and communication skills.

Good command of English and Chinese (for literature review and communication).

What We Offer

Remuneration:

Competitive salary package along with the Mandatory Provident Fund (MPF) scheme.

A flat organizational structure where your experimental breakthroughs directly shape commercial products.
