Process Development Engineer (Carbonation)

San Francisco, CA /

Full Time
Company Summary
Heirloom’s mission is to accelerate our planet’s transition to a carbon negative society. We will capture 1B tons of CO2 from the atmosphere by 2035 (equivalent of ~60M Americans’ annual emissions today), and build a multi-billion dollar business along the way. The problem we are solving is that according to IPCC, billions of tons of CO2 need to removed from the atmosphere (in addition to decarbonizing the entire economy) by 2050 to keep global warming to 1.5 °C, but current technologies are too expensive and not scalable to the volume necessary.

Unlike traditional engineered removal solutions, our Nature published technology combines the natural properties of minerals (carbon mineralization) with engineering to provide a low cost path to $50/tCO2 for Direct Air Capture (DAC), the cost at which carbon removal will be transformative. 

Our early customers are corporations and other entities that need to reduce and offset their carbon emissions to meet compliance requirements or carbon pledges. Our go-to-market strategy allows us to be unit profitable from day one, and reach >$1B in revenue just from existing markets and pledges. Our $100B opportunity lies with carbon markets set for creation in the EU, US, and other markets. 

About the job
The Heirloom team is on a path to creating a sustainable, scalable, and economically viable carbon removal system. This technology - which requires a unique blend of geology, chemistry, industrial engineering, and process engineering -  doesn’t yet exist at the scales necessary to make a difference, so we need to build it ourselves. 

We are looking to hire a dedicated process development engineer to assist in Heirloom’s R&D projects related to mineral carbonation. You and the research team will work to design and implement experiments targeted at scaling the CO2 carbonation process, including process design, optimization, integration, and characterization. In this role you will contribute to developing Heirloom’s carbonation process to operate 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 the carbonation performance of mineral feedstock at scale under varying conditions.
    • Collect, interpret and analyze data, compile results, and prepare reports.
    • Perform routine characterizations 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. 

Minimum Qualifications

    • 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.
    • Strong attention to detail and experience with critical problem solving.
    • Self-motivated and willing to learn and adapt in a fast-paced organization.

Desired Qualifications

    • Prior experience working in a laboratory environment.
    • Knowledge of material 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.
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! If not, but you know someone who might be interested, please share this post. 

We are committed to cultivating a culture of inclusion and equity, starting with our commitment to fostering diversity within our Heirloom team. We are able to grow and learn better with a diverse team, which is exactly what our planet needs. We encourage members of traditionally underrepresented communities to apply, including people of color, people with disabilities, women, LGBTQ+ people, and veterans.
