Heirloom is on a mission to restore balance to our atmosphere.&nbsp;We are removing 1 billion tons of carbon dioxide by 2035, using natural processes to engineer the world's most cost-effective Direct Air Capture solution.
Naturally occurring minerals - alongside forests, soils, and the ocean - are one of our planet's most vital carbon sinks. Over geological timescales, carbon dioxide in the air and water chemically bind to these minerals and permanently turn to stone. Our technology enhances this natural process, called&nbsp;carbon mineralization,&nbsp;to help minerals absorb CO2&nbsp;from the ambient air in days, rather than years. By combining the best of engineering and nature, we can offer the most cost-effective and scalable Direct Air Capture solution in the world.

Harnessing natural processes to capture 1 billion tons of carbon dioxide by 2035.

<h1>About Us </h1>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.  <h1>Our Commitment to Diversity, Equity, and Inclusion </h1>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. This role will oversee the full scope of People Operations—including benefits, compensation, compliance, payroll, HR systems, onboarding, offboarding, and more.

The build includes demolishing legacy equipment, upgrading plant utilities, and installing a first-of-its-kind calciner that will advance our direct-air-capture technology. As the on-site Construction Lead, you’ll steer the project from early groundworks through commissioning—keeping schedules tight, budgets intact, safety uncompromised, and quality uncompromising. If you thrive on juggling RFIs, inspections, and contractor coordination, you’ll be at the heart of one of climate tech’s most exciting industrial retrofits. After construction, you’ll shift into a Technical Program Manager role, using field insights to refine and scale Heirloom’s technology for future sites. In short, you’ll break ground and then break new ground, accelerating the race to remove CO₂ at scale. About You You bring 3 + years of on-site construction-management experience—ideally on projects with structural, civil, and MEP complexity. You know how to marshal trades, handle RFIs, manage budgets, enforce quality, and keep critical paths moving under dynamic, real-world conditions. Whether coordinating a utility shutdown for tie-ins or pivoting when a last-minute design change hits, you stay calm, collaborative, and solutions-oriented. You’re excited by the prospect of applying this hands-on construction knowledge to broader program management—looking forward to reviewing test plans, ensuring equipment commissioning runs smoothly, and providing real-world feedback to drive future design improvements. You thrive in high-stakes settings where collaboration and adaptability are crtical, and you’re ready to grow into a technical program management role that influences Heirloom’s global scale-up. Above all, you’re determined to be on the front lines of climate tech, turning bold ideas into on-the-ground reality—and then refining them for the next big build.<h1>Our Principles</h1>Radical Honesty means we are open, transparent, and inclusive in everything we do.
