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.

The Role

The process development team is tasked with innovating to develop new processes and improve existing ones. This internship is a great opportunity to use your science or engineering background and apply it to benchtop and at-scale processes that help remove carbon dioxide from the atmosphere.

At Heirloom, you will work independently on an innovative carbon capture project, and collaborate with colleagues with a wide range of science and engineering backgrounds. You will use your laboratory skills to run carbonation tests according to standard operating procedures (SOPs), and help develop new ones. You will collect and analyze process performance data on one of Heirloom’s carbonation systems, create detailed reports and communicate findings to the team. Self-motivation and attention to detail are key markers for success.

What you will bring

You have a background in chemical engineering, chemistry, material science, industrial engineering or a related field in science or engineering and are looking to apply your strong technical background to mitigate the effects of climate change!

You have strong critical thinking and problem solving skills, with good attention to detail. You communicate complex concepts well in verbal presentations and written reporting of data, and are comfortable working cross functionally and collaborating with others.

This role is ideal to help you further develop your technical skills in your chosen field of study, or can help you pivot into the carbon capture space.

You don’t have to have every listed requirement and skill to be a great fit - you may even teach us something about what we should be looking for! If you connect with our mission and this opportunity, and think you have the skills to succeed, please apply!
