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.

About the Role

As a Process Design Engineer, you will spearhead the process design for our direct air capture R&D projects. Your role involves leading planning and design of critical projects, including first of a kind technology. Collaboration will be critical as you will partner closely with our plant design team to ensure delivery of top-tier work products for projects. This entails conducting process conceptual design, engineering calculations, reviewing detailed design drawings, and preparing technical reports and specifications. Your responsibilities extend to evaluating alternative process design concepts, working in interdisciplinary teams to create integrated designs, and working with vendors to spec and procure capital equipment. Your ability to proactively seek innovative technologies and design tools for design is essential, contributing to our commitment to sustainable development goals.

What you will bring

In your 3+ years of experience, you have led process design on multiple projects, showcasing strong teamwork within interdisciplinary teams. You possess expertise in developing heat/material balances, creating PFDs, and leading P&ID generation. Your experience includes fluid hydraulic calculations for equipment and familiarity with engineering requirements, client specs, and relevant codes (API, ANSI, ASME, NFPA). Communication skills are essential for collaboration within the design team to be able convey technical concepts and ideas within the team and beyond.

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!
