  • 2+ years industrial experience working as a materials scientist, chemical engineer, or membrane scientist in addition to the above.
  • High-level proficiency in membrane fabrication methods such as hollow fiber spinning and phase inversion.
  • Hands-on experience with gas permeation systems, gas chromatography, SEM, DSC, and TGA.
  • Polymer synthesis capability is preferred but not required

What We Can Offer You

  • Opportunity to contribute to addressing one of the biggest industrial decarbonization and energy efficiency challenges of this century.
  • Work in the heart of the most innovative square mile in the world and the most exciting hub for clean tech.
  • High leadership and growth potential joining our company at a critical stage with strong momentum backed by leading venture capital firms.
  • Access to competitive salary and equity packages.
