This position is part of a collaborative research initiative between Department of Chemistry, The Chinese University of Hong Kong (CUHK) and Xianhong Science (Hong Kong) Ltd., specialising in advanced solder mask inkjet ink development. The project aims to accelerate innovation in Drop-on-Demand (DOD) inkjet ink formulations for next-generation inkjet ink formulations for solder mask printing. The appointee will work closely with both academic researchers and industry professionals.
We are seeking an experienced Drop-on-Demand (DOD) Inkjet Ink Formulation Specialist to contribute to cutting-edge research and development. The role involves developing, optimising, and scaling advanced solder mask inkjet inks, bridging academic research with real-world industrial applications.
Applicants should have (i) a Bachelor%27s degree (for Research Assistant) or a Master's degree plus four years of post-qualification experience (for Research Associate) (ii) minimum two to three years of experience in an inkjet ink company (industrial or commercial) (iii) demonstrated expertise in inkjet ink formulation, particularly for DOD systems (iv) strong background in chemistry, materials science, or chemical engineering (v) knowledge of fluid dynamics, colloidal chemistry, and material compatibility (vi) familiarity with printhead technologies and jetting requirements (vii) experience with analytical characterisation and testing methods and (viii) the ability to work in a multidisciplinary, collaborative research environment. Experience with UV-curable, solvent-based, or water-based ink systems or translating research into scalable industrial processes are preferred. Background in industrial applications such as packaging, textiles, electronics, or additive manufacturing will be an advantage.
The appointee will be responsible for (a) developing and optimising inkjet ink formulations for DOD printing technologies (b) conducting research on pigments, dyes, solvents, binders, and additives to enhance performance (c) evaluating inkjet ink properties such as viscosity, surface tension, stability, and jetting behavior, printed solder mask properties (d) collaborating with university researchers and industry engineers on formulation and application challenges (e) performing testing, validation, and troubleshooting of ink performance and (f) assisting in scale formulations from laboratory research to pilot and industrial production Contribute to technical reports, publications, and potential intellectual property.
Applicants should submit the following supporting documents in the online application: (1) CV and (2) a brief summary of relevant experience in inkjet ink formulation.
Appointment will be made on contract basis for one year.

The Chinese University of Hong Kong (CUHK) is a public research university in Shatin, Hong Kong, formally established in 1963 by a charter granted by the Legislative Council of Hong Kong. It is the territory's second-oldest university and was founded as a federation of three existing colleges – Chung Chi College, New Asia College and United College – the oldest of which was founded in 1949.
CUHK is organized into nine constituent colleges and eight academic faculties, and remains the only collegiate university in the territory. The university operates in both English and Chinese, although classes in most colleges are taught in English. Four Nobel laureates are associated with the university, and it is the only tertiary institution in Hong Kong with recipients of the Nobel Prize, Turing Award, Fields Medal and Veblen Prize sitting as faculty in residence.
