Your qualifications

 

  • Strong team player and getting-things-done mentality

  • Enrolled in a Bachelor’s or Master’s program in chemical engineering, materials science, microsystems engineering, physics, or a related field (e.g. Sustainable Systems or Sustainable materials)

  • Interest in fuel cells, electrolysis, electrochemistry, or energy materials.

  • Practical skills in laboratory work; experience with coating, printing, or electrochemical measurements is an advantage.

  • Independent, reliable, and team-oriented working style.

  • Proficiency with common office software

  • Business fluency in English

 

What we offer

 

  • Opportunity to join a leading German green-tech start-up
