Research & Development Dispersion Chemist

About the role

HP is looking for a Research & Development Dispersion Chemist in Singapore to act as a technical leader in pigment dispersion science and technology development. The role drives innovation in dispersion formulation and solves complex formulation and scale-up problems at the intersection of pigment/dispersant chemistry, colloidal stabilization, process engineering, analytical interpretation and ink performance, helping shape next-generation technologies for HP's pigment ink portfolio.

Key responsibilities

• Lead advanced dispersion development programs from concept through manufacturing implementation.
• Identify emerging technologies, materials and process innovations that create competitive advantage.
• Lead dispersion-ink related development across multiple product platforms and across laboratory, pilot and manufacturing scale-up.
• Apply colloidal science, surface chemistry, rheology and stabilization principles to optimize formulations and processes.
• Partner with manufacturing teams on technology transfer and production readiness.
• Design hypothesis-driven experiments using DOE and statistical tools, interpret complex datasets and turn findings into actionable technical strategies.
• Collaborate with analytical, ink formulation, manufacturing, supply chain and supplier teams, and lead technical reviews for management and stakeholders.
• Mentor chemists, drive capability development within the Dispersion Center of Excellence and exercise independent scientific judgment.

Required profile

• Ph.D. in Chemistry, Chemical Engineering, Materials Science, Polymer Science or a related field.
• 8-10+ years of industrial R&D experience in pigment, dye or dispersion chemistry, polymers in solution, wet chemistry or ink formulation, and colloidal/interface chemistry.
• Proven track record leading complex research and technology programs from concept through commercialization.
• Experience designing and analyzing multivariable formulation and process experiments with DOE and statistical tools, and leading formulation studies, investigations and scale-up projects.
• Strong written and spoken communication skills.

Preferred experience

• Inkjet printing technology and color science.
• Hands-on experience developing aqueous dispersions, inks, coatings, paints, colorants or other particle-stabilized systems.
• Manufacturing process development and scale-up, intellectual property generation and patents.
