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.

About the Role

In this exciting role, you will innovate novel designs to tackle the diverse challenges associated with processing feedstock for our CO2 capture process. You'll fabricate and assemble prototypes, continually iterate based on lessons learned and push our ability to improve our technology at a rapid pace. Your approach will prioritize holistic design, considering both individual components and system interfaces to ensure seamless integration and overall system success. Additionally, you'll actively incorporate feedback from fabrication, maintenance, and operations teams to enhance design efficiency and effectiveness. Sharing your insights and knowledge with the broader engineering organization will contribute to the collective expertise to ensure continuous growth as we push the limits on research and technology advancement.

What you will bring

The ideal candidate will possess a Mechanical Engineering degree coupled with 3+ years of hands-on experience in component design and prototyping. You specialize in designing prototypes that are flexible and iterative to ensure rapid advancement of our key technologies. Your expertise encompasses designing and sourcing complex components to intricate machines that can operate in high-heat environments as well as designing structures and fixtures to support equipment and testing. Additionally, you excel in the design and development of laboratory-scale equipment tailored for testing baseline technology. With a focus on innovation, you are adept at addressing diverse challenges, particularly in Carbonating and Calcining feedstock for CO2 capture, while also proficient in fabricating and assembling prototype fixtures to accelerate testing processes. Your iterative approach, coupled with a keen eye for system-level design, ensures the success of entire systems by incorporating feedback from various teams and sharing knowledge to foster collective growth within the engineering organization.

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 are passionate about this opportunity and think you have the skills to succeed, please apply!
