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

Heirloom is committed to diversity and building an equitable and inclusive environment for people of all backgrounds and experiences.  We believe wholeheartedly that building a diverse company is critical to Heirloom’s success.  We especially encourage members of traditionally underrepresented communities to apply, including women, people of color, LGBTQ+ people, veterans, and people with disabilities.

The Role
You will be responsible for design and validation of the factory material flow, from our first pilot plant to full scale deployments around the world. 

You will design, test, and build mechanical systems that connect our carbon capture equipment together. This is the connective network that enables the system to run smoothly. Material flow covers conveyance, buffering and tracking our carbon capturing media as it loops through the system. You will utilize your knowledge from other bulk solids handling industries and your creative critical thinking to reimagine them for our unique system needs. You revel in both complexity and uncertainty and delight in breaking down and translating big problems into actionable and testable system requirements. As we scale, you will help us design and build the infrastructure to operate at the industrial levels necessary to effect global change on our CO2 footprint. Your work has the potential to directly shape our fight against climate change. 

What you will do

    • Use 3D tools to design, build, and test our novel material flow process to capture CO2 at massive scale in the billions of tons
    • Get hands-on to design, build, and test rapid proof of concept prototypes
    • Independently execute on and troubleshoot designs
    • Define and design product modules to support off site fabrication and assembly with reduced onsite construction
    • Drive system level analysis to consider trade-offs between function, deployment time, operational costs, and capital  investment
    • Produce material flow diagrams 
    • Develop equipment requirements and work with vendors to ensure their success
    • Maintain and build out documentation communicating system design and intent 
    • Communicate your ideas and decision clearly and concisely with documentation

What you will bring

    • BS / MS in Industrial, Manufacturing, Mechanical Engineering or equivalent through work experience
    • 4+ years work experience in a directly relevant field
    • Direct experience with material flow and factory design and construction, with an emphasis on modularity
    • Proven experience with managing powder bulk solids material conveyance, storage / buffering, and throughput measurement 
    • Experience with OEE and line balancing 
    • Experience with 3D CAD (Solidworks, NX, Revit)
    • Experience with Agent based and discrete event modeling (AnyLogic)
    • A self-starter who is comfortable driving multiple components of a complex system

    • 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! 

Our Principles

    • Radical Honesty means we are open, transparent, and inclusive in everything we do. We aren't scared to challenge each other, but bring clear motives and our best intentions when we do.
    • Persistent Optimism means we carry an infinite amount of optimistic energy with us on our journey, constantly chipping away at what may seem insurmountable.
    • Continual Discovery means we maximize our learning rate.  Compounding knowledge is our key to victory - we continuously hone our crafts, seek the fastest paths to new learning, and are quick to absorb new knowledge.

Why you should join Heirloom

    • We are solving the engineering problem of our generation. Climate change is an existential threat, and we need as many of the world’s motivated minds as possible to help. There is no greater challenge or opportunity than fighting climate change.
    • We have done this before. We have done this before.  We’re engineers, scientists, and concerned humans from a variety of backgrounds and experiences who are pooling our knowledge and skills to collectively build a more equitable, prosperous future for all.
    • We are a united, resilient, and optimistic bunch. We are all here for the same reason - to slow climate change. We recognize the magnitude of the challenge ahead of us, and believe we can solve it. We can see a hopeful future where we eventually reverse climate change. It won’t be easy, but we won’t quit.
    • We are backed by the best climate partners in the world. We’re well funded by investors from Breakthrough Energy Ventures, Ahren Innovation Capital, Carbon Direct, Microsoft, Lowercarbon Capital, ARPA-e and the National Science Foundation. Our early customers include Stripe, Shopify, and Klarna, and we’re building durable partnerships that enable us to tackle this decades-long problem.
