Job Description

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 RoleWe are looking to hire a dedicated process development engineer to assist in Heirloom’s R&D projects related to our novel direct air capture process. You and the research team will work to design and implement experiments targeted at scaling the CO2 carbonation and material movement processes, including process design, optimization, integration, and characterization. In this role, you will characterize material flowability and develop key process requirements that contribute to Heirloom’s operation at the industrial levels necessary to effect global change and reduce our CO2 footprint. This position requires good communication, excellent attention to technical detail, and a strong desire to do hands-on work.

What you will do

  • Design and perform testing using a variety of methodologies to assess materials flowability and broader rheometric properties under varying conditions.
  • Design experiments and perform tests to probe material properties, flowability, and other concepts related to powder rheology.
  • Evaluate carbonation performance of mineral feedstock at scale under varying conditions.
  • Collect, interpret, and analyze data, compile results, and prepare reports, including the use of statistical analysis.
  • Use prototype and laboratory equipment to characterize process performance and suggest improvements.
  • Perform routine characterizations and tests of mineral samples.
  • Identify and suggest improvements for methods and procedures.
  • Work as a part of a team of world-class scientists and engineers to execute on our development plans, with an urgency rooted in the importance of our mission. 

What you will bring

  • Bachelor's degree in Engineering (such as Chemical, Process, Materials Engineering, or a related field), Applied Science (Materials Science, Chemistry, Physics, or related field) or equivalent practical experience.
  • Prior experience working in a laboratory environment.
  • Experience with process development and requirements generation.
  • Experience with mineral characterization and/or rheometric analysis.
  • Strong attention to detail and experience with critical problem solving.
  • Self-motivated and willing to learn and adapt in a fast-paced 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! 

Bonus Points

  • Master's degree in Engineering (such as Chemical, Process, Materials Engineering, or a related field), Applied Science (Materials Science, Chemistry, Physics, or related field) or equivalent practical experience.
  • Knowledge of mineral characterization techniques, fluid dynamics, and/or process scale-up. 
  • Technical writing and experimental documenting/reporting.
  • Experience with critical problem solving and complex engineering systems.
  • Previous experience working in high output teams.

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.
