About the role

As our Membrane Stack Specialist, you will play a crucial role in our team of scientists and engineers in the development of our groundbreaking water and salt-based flow battery technology. As we move towards commercialization, you will work in our brand new office, workshop, and lab at Alphen a/d Rijn.

As a Membrane Stack Specialist, you will be instrumental in optimizing the heart of our acid-base flow battery system: the membrane stack. You will be responsible for the design, development, and performance of this critical component, focusing on the selection and integration of key materials and techniques.

What you’ll be doing

  • Membrane selection and characterization: Evaluate and select optimal ion-exchange membranes for superior performance and compatibility with other battery components. This includes analyzing properties like ionic conductivity, selectivity, chemical stability, and durability.
  • Spacer design and optimization: Design and optimize spacer materials to ensure proper electrolyte flow distribution within the stack while preventing membrane-to-membrane contact. This involves considering factors like porosity, channel geometry, and mechanical strength.
  • Compression method development and characterization: Develop and implement effective compression methods to ensure optimal stack performance and prevent leakage. This may involve analyzing the effects of compression force on performance parameters.
  • Stack assembly and testing: Participate in the assembly and testing of membrane stacks, employing specialized equipment and techniques to ensure quality and performance standards are met.
  • Data analysis and troubleshooting: Analyze data from stack testing to identify performance issues, troubleshoot problems related to membrane selection, spacer design, or compression, and suggest improvements to the overall stack design and fabrication process.
  • Technical documentation: Prepare and maintain detailed technical documentation related to membrane selection, spacer design, compression methods, stack assembly procedures, and testing results.
  • Staying informed: Stay up-to-date on the latest advancements in membrane technology, spacer materials, and acid-base flow battery research, actively seeking opportunities to incorporate new knowledge and methodologies into your work.

Function requirements

Education and experience:

  • Master's degree in Chemical Engineering, Materials Science, or a related field (or equivalent experience).
  • >2 years of relevant industry experience

Knowledge and skills:

  • Strong understanding of membrane science and technology, including ion transport phenomena, membrane characterization techniques, and membrane selection criteria.
  • Experience in working with ion-exchange membranes for EDI type stack design and application is highly desirable.
  • Strong analytical and problem-solving skills with a focus on detail-oriented work.
  • Excellent communication, collaboration, and documentation skills.
  • Ability to work independently and as part of a team in a fast-paced environment.
  • Meticulous attention to detail and a commitment to quality.
  • Proficient in English.

Considered a plus:

  • Familiarity with flow battery technology and its principles.
  • Proficiency in Dutch, spoken and written. 

What you can expect

  • A fast-growing, impact-driven and multicultural work environment
  • Open and collaborative learning culture
  • Attractive compensation package, including stock appreciation rights program, green pension scheme (50% covered by company), and collective health insurance plan providing discount over additional insurances
  • Flexibility and eye for healthy work-life balance, and 25 vacation days
  • Company bike, for travel from and to the office
  • Regular team and social events
