About the role

About Heimdal

Heimdal builds machines that extract calcium and magnesium carbonate from the ocean to make carbon negative glass, concrete and other critical building materials. Concrete alone is responsible for 8% of global CO2 emissions, and we’ve created the world’s first carbon negative concrete. We use electricity to alkalinize seawater and extract precipitates of calcium and magnesium carbonates. We are working with established multinationals in glass and concrete to supply them with the world’s first carbon negative limestone for use in their manufacturing processes. We are building our pilot facility on the Big Island in Hawai’i in partnership with the desalination facility owned and operated by Terraformation. We are venture backed by Y Combinator, Cathexis Ventures, Sam & Max Altman’s Apollo Projects, Marc Benioff and many other investors.

Objectives and responsibilities

  • Design and run experiments to deepen understanding of carbonate mineral extraction from the ocean
  • Analyze and document results
  • Write up and submit results and analysis for publication in peer reviewed scientific journals
  • Provide expert input to patent work and possible grant applications


  • PhD in a discipline related to chemistry (or at least have commenced a PhD)
  • Experience independently designing and running laboratory experiments
  • Published experimental papers in recognized peer reviewed journals
  • Candidates must be able to work independently and take responsibility for driving progress without micro-management
  • Experience and/or genuine interest in working in a start-up
