Senior Membrane Application Scientist

Our client is seeking an experienced Senior Membrane Application Scientist with strong membrane chemistry expertise, analytical capability, and hands-on pilot-scale testing experience.

This role focuses on evaluating and developing an advanced membrane technology platform, helping the business understand performance boundaries, technical advantages, and potential applications across customer and industrial process streams.

The successful candidate will be a strong chemist with a practical approach to membrane testing, fluid handling systems, and small to medium-sized pilot plants. They will be comfortable designing experiments, interpreting complex datasets, troubleshooting process challenges, and translating findings into clear technical recommendations.

Working closely with Innovation, Engineering, Commercial, and customer teams, the successful candidate will support laboratory trials, pilot testing, customer demonstrations, commissioning activities, and technical reporting. The role will involve international travel to support customer trials and represent the business at customer sites globally.

• Design and execute laboratory and pilot-scale test programmes to assess membrane performance across a range of feed streams and operating conditions.
• Apply strong chemical understanding to investigate membrane selectivity, fouling, cleaning behaviour, stability, and operating limits.
• Develop and utilise appropriate analytical methods to understand feed chemistry, permeate quality, concentration effects, and overall process performance.
• Analyse experimental data to identify performance trends, limitations, benefits, and opportunities for improvement.
• Prepare clear technical conclusions and recommendations based on test results and chemical analysis.

• Support the development and validation of the company's advanced membrane technology platform through structured testing and application studies.
• Help define the capabilities, benefits, and potential applications of the technology across water treatment, industrial separations, resource recovery, and related markets.
• Design experiments to compare product performance under realistic customer operating conditions.
• Identify new use cases and application opportunities where the technology can deliver value.
• Work closely with Innovation, Engineering, and Commercial teams to translate customer requirements into practical test plans and technical development activities.

• Support laboratory, pilot, and field trials at company and customer sites, including international locations.
• Assist with the setup, operation, troubleshooting, and commissioning of small to medium-sized membrane pilot systems.
• Work practically and safely with pumps, pipework, tanks, instrumentation, sampling systems, and membrane test rigs.
• Support customer trials through planning, data collection, result interpretation, and progress communication.
• Provide technical support during pilot campaigns, including troubleshooting process issues and recommending operational improvements.
• Capture customer feedback and trial learnings to support product development, application guidance, and future commercial opportunities.

• Independently manage assigned projects, test programmes, and customer trial activities with clear priorities, milestones, and timescales.
• Coordinate activities across internal teams and external partners to ensure projects are delivered safely and effectively.
• Prepare high-quality technical reports, customer summaries, presentations, and application notes.
• Present technical information confidently to customers, partners, and internal stakeholders.
• Support customer-façing meetings, product demonstrations, and technical discussions as a credible membrane technology specialist.
• Maintain regular reporting to management on progress, risks, results, and recommendations.

• Maintain detailed records of experimental methods, raw data, analysis, conclusions, and project decisions.
• Ensure all testing and pilot activities are completed in…
