Job description

Senior Powder Process Engineer Technology Specialist (Titanium Dioxide)

Lead the optimisation, scale-up and standardisation of critical post-processing operations for titanium dioxide and functional powder materials. The role converts laboratory and pilot-scale work into safe, stable and cost-effective industrial production while resolving process constraints at the manufacturing site.

Key responsibilities

Optimise and control critical post-processing parameters for titanium dioxide and functional powder production, including ultrafine grinding, air classification, wet or dry surface coating, drying and packaging.

Lead process design and on-site commissioning for new projects, taking conventional, functional and photocatalytic titanium dioxide products from laboratory and pilot trials through to tonne-scale industrial production.

Diagnose and resolve production bottlenecks at the plant, including powder agglomeration, uneven particle-size distribution, non-uniform coating, poor dispersibility and excessive oil absorption.

Develop core technology patents and contribute to Hontai Global Limited's proprietary intellectual-property portfolio.

Release capacity limits, reduce energy consumption and deliver targeted modifications for key equipment, including jet mills, high-energy bead mills, large coating reactors and flash dryers.

Create and maintain production SOPs, process cards and material-balance sheets to support stable, safe and repeatable process execution.

About you

PhD in Materials Science and Engineering, Chemical Engineering, Colloid and Interface Chemistry, or a related discipline; exceptional master's-degree candidates may be considered.

3–5+ years of hands‑on process engineering or production technology experience in titanium dioxide, inorganic pigments, ultrafine calcium carbonate, barium salts or other large‑scale inorganic functional powder plants.

Demonstrated R&D and/or production experience in photocatalytic materials, titanium dioxide modification or powder engineering.

Industrial control of inorganic powder surface modification, including coating and encapsulation processes.

Operation, parameter tuning and basic maintenance of industrial ultrafine grinding and precision air‑classification equipment.

Ability to read and improve basic process drawings, including P&IDs and equipment‑layout drawings.

Structured troubleshooting, root-cause analysis and on‑site coordination in a manufacturing environment.

Experience commissioning a new powder‑material production line.

Knowledge of photocatalytic materials and/or nanoscale powder-processing technologies.

Practical, solution-oriented and comfortable working on the production floor with strong site coordination and technical communication skills.
