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

Are you a talented modeling and simulation engineer that enjoys using computational tools to solve hard problems? We are seeking a skilled Modeling and Simulation Engineer to join our world-class team of engineers, scientists, and designers to help develop and optimize our direct air capture process. 

Joining the scaled systems equipment design team as a modeling & simulation engineer, your role will involve developing intricate Computational Fluid Dynamics (CFD) models, Design of Experiments (DOEs), and other simulations. Utilizing existing software and a deep understanding of engineering principles, you'll create both component-scale and large-scale models reflective of Heirloom’s direct air capture systems. Collaborating closely with design engineers, you'll iterate on design simulations to inform product design requirements. Additionally, you'll contribute to the design of platforms for model validation, conduct testing, and incorporate insights gained to enhance model accuracy and effectiveness.


What you will bring

We're looking for someone with a strong engineering background and experience in fluids modeling at small and large scales.

You're comfortable working with ANSYS Fluent and Ansys Spaceclaim/Discovery, and related simulation tools such as Ansys Mechanical, Ansys Rocky, etc. Bonus points if you have experience with multiphase flow modeling, species transport modeling, developing custom-built code using tools like Python, and/or creating reduced order models. 

And, you're great at presenting technical data to both technical and non-technical stakeholders. If that's you, we'd love to hear from you!

This is an exciting opportunity for someone who is passionate about using simulation modeling to develop innovative solutions to combat climate change! If you are a team player who thrives in a fast-paced, dynamic environment, we encourage you to apply for this Modeling and Simulation Engineer position.

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.
