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

In this role, you will be joining the scaled systems mechanical design team and will be focused on architecting the next-generation carbonation equipment. The carbonation equipment is part of Heirloom’s core technology and requires a low-cost, scalable, and reliable design to meet our goal of removing 1 billion tons of CO2 by 2035. In this role, you will be expected to constantly challenge our assumptions and push the limits of design and manufacturing to achieve our ultimate targets.

As part of the team, you will independently lead the development of several large, modular, and yet lightweight assemblies of steel, plastic, and composite through their entire product lifecycle with cost and reliability as key drivers. In addition to owning all technical aspects of your design (geometry, interfaces, material & plating selection, fastener selection), you will drive the end-to-end definition of your design, including requirement definition, risk, analysis, and system validation. You will design parts for many distinct manufacturing processes including but not limited to sheet metal forming (stamping & press brake), injection molding, composite layups, casting, and thermoforming. Working with suppliers and our supply chain team, you’ll provide in-depth design for manufacturing and assembly feedback required to ensure that our designs are cost-efficient, robust, and capable of high-quality results at scale.

What you will bring

Whether you’re working solo at a small start-up, or owning projects on a larger team, this much is clear: you will be an experienced (5+ years) Mechanical Design Engineer with a background in design for high-volume production of sheet metal and plastic parts. You will bring creative solutions to design parts that are optimized for high reliability and low cost. Having taken product(s) through the entire product lifecycle (EVT/DVT/PVT) process repeatedly has taught you to solve technically complex problems using mechanical fundamentals and data-driven methodologies. You have experience with tools & methods like or similar to Finite Element Analysis (FEA), accelerated test methods & statistics, bolted joint analysis, root cause analysis (RCA), design of experiments (DOE), Geometric Dimensioning and Tolerances (GD&T), and supplier Quality Control methods.

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.

Maximize our learning rate means we're always in discovery mode. 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.
