- 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.
What they look for
Required Qualifications
- A bachelor or higher degree in chemistry, materials science, chemical engineering, or a related field.
- Experience with the development and execution of structured test plans and qualification protocols.
- Hands-on mentality: You are passionate about being in the lab, running experiments, and solving problems practically.
- Fluency in English (Dutch is a plus).
- Experience with rheology, particle characterization, or analytical chemistry. Preferably experience in colloidal systems, dispersions, or pigment-based formulations.
- Knowledge of electrophoretic systems, surfactants, or dispersion chemistry.
- Ability to clearly communicate and substantiate technical choices.
What they look for
- Attention to detail — Ensuring measurements, sample preparation, and documentation are precise and reproducible.
- Structured documentation & communication — Writing clear test reports, explaining results to non‑chemists, and presenting findings logically. Keeping accurate logs, batch records, and traceable test histories.
- Time management — Planning experiments, managing long‑running tests, and prioritizing critical qualification tasks.
- Problem‑solving — Diagnosing unexpected test results, contamination issues, or stability failures with structured reasoning.
- Safety awareness — Maintaining chemical safety, risk assessment, and disciplined lab behaviour.
- Continuous improvement mindset — Iterating test methods, refining protocols, and improving reproducibility.
