- Test engineering — Develop & execute test plans, qualification protocols, reliability tests, and structured experiments to validate ink performance.
- Ink formulation & development — Create, refine and optimize electrophoretic inks, dispersions, and additives from concept through to validated formulation.
- Material characterization — Define and perform measurements (eg. viscosity, particle size, zeta potential, stability, ageing, and optical property measurements).
- Hands-on lab work — Prepare batches, run experiments, analyse failures, and implement improvements.
- Process development — Scale formulations from lab to pilot production, ensuring consistency, reproducibility, and manufacturability.
- Documentation & compliance — Maintain formulation records, test reports, chemical safety documentation, and release files.
- Stakeholder alignment — Work closely with electronics, mechanics, manufacturing, suppliers, and project management.
