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

As a Systems Engineer - Regeneration, you will play a pivotal role in developing Heirloom’s regeneration technology. Your primary responsibility will be to design experiments and models to drive improvements in Heirloom’s thermal decomposition process. This role requires a strong fundamental physics background to design models which are complex enough to capture the desired phenomena but simple enough to parameterize and experimentally determine values for each parameter.

You’ll design experiments to investigate the thermal decomposition of CaCO3 into CaO. Instrument and monitor your experiments meticulously, ensuring accurate data collection and analysis. Utilize your expertise in data analysis and modeling to interpret the results and extract critical parameters governing the decomposition process. Make use of thermal/hydrodynamic modeling software to predict the expected thermal decomposition performance at different scales. Continuously troubleshoot and refine your experimental setups based on data insights for optimal outcomes. Lastly, you’ll be collaborating with cross-functional teams to enhance your understanding and efficiency of the regeneration process. 

What You Will Bring

While a preference is given to candidates with a PhD, your strong background in Engineering, Science, or a related field at the MS or BS level will also be considered. Your proven experience in designing, instrumenting, and analyzing complex experimental setups is crucial for this role. Additionally, your proficiency in data analysis and modeling, preferably with knowledge of ANSYS, Python, or other modeling software, is highly valued.

Ideally, you would have experience in both finite element modeling and discrete particle method modeling. A hands-on approach, coupled with acute attention to detail in experimental work, is essential. Furthermore, your ability to troubleshoot effectively when experimental data does not align with expectations is a key attribute for success in this position.

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

Target compensation for this role is between $120,000 and $155,000 depending on level and experience.
