About Us 

All across the world, from the azure pools of Turkey and Oman to the travertine terraces of Yellowstone, our planet quietly pulls carbon dioxide from the air and turns it to stone. For eons, Earth has relied on this process to balance its carbon cycle. What if it could be harnessed? What if we could do it faster, in larger quantities, and at a low enough cost to make it an effective tool in the fight against climate change? 

At Heirloom, we are turning that into reality. We use the natural carbon capture properties of abundant minerals to pull CO2 from the air, and store it permanently underground. We come to work every day to slow climate change, and are united behind a single, common goal - to remove 1 billion tons of CO2 from the sky by 2035, and to not stop before we get there.  

We bring together the precise recipe of science, technology, know-how, and strategy necessary to make low cost, high quality carbon removal a reality. If we’re successful, we will directly mitigate climate change, build a world we can proudly hand over to our children and grandchildren, and catalyze an industry that will rival the largest the world has ever seen. If you want to change the planet, come join us. 

Our Commitment to Diversity, Equity, and Inclusion 

As temperatures continue to rise, individuals from marginalized communities will face the harshest impacts of climate change.  We believe wholeheartedly that building a diverse company is critical to Heirloom’s success.  To accomplish this, we’ve put recruiting, hiring and retaining individuals from underrepresented groups at the top of our priority list. 

We encourage you to apply if you identify as Black, Native Hawaiian or Pacific Islander, American Indian or Alaskan Native, Hispanic or Latino, LGBTQ+ – or with any other underrepresented group – even if you don’t tick all the boxes in the description below. 

Don't see a role that directly fits your skillset? Never fear! Heirloom is always looking for talented and passionate Research Scientists to join our team. Heirloom's Research Science team focuses on discovering and evaluating fundamental and applied science that can be used for removing CO2 directly from the air. If you have expertise in geochemistry, carbonate chemistry, high temperature kinetics, reactor design, complex experimental design, or similar skillsets, we want to hear from you!
