Factory Systems Engineer

San Francisco, CA /
Engineering /
Full Time
Company Summary

Our 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. 

Over the next 18 months, we will de-risk our cost estimates, build our first deployment, and validate the commercial viability of this technology.

About the job

The Heirloom team is on a path to creating the world’s first 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 for dedicated and driven hardware scientists and engineers to help us design and build systems that capture CO2 directly from the air and enable us to process it into a variety of products (carbon credits, carbon negative materials, etc).

You will design and build the mechanical systems to capture and measure the CO2 we capture from the air we breathe.  While our laboratory results demonstrate the general concept, we must scale from lab bench to industrial scales.  You will help shape and drive exploratory research and development phases to evaluate and test new ideas and setups.  You revel in both complexity and uncertainty and delight in breaking down and translating huge problems into actionable and testable systems requirements.  As we scale, you will help us design and build the infrastructure necessary to operate at the industrial levels necessary to effect global change on our CO2 footprint.  Your work has the potential to directly shape our fight against climate change. 


    • Define and design aspects of factory layout, and component interaction. Focus on material flow, material conveyance, material storage
    • Drive system level analysis to consider trade-offs between function, deployment time, operational costs, and capital  investment
    • Work closely with mechanical design, researcher, and operations teams to define and communicate system needs. We are looking for very interdisciplinary individuals with different experience levels.
    • Work with external suppliers and partners to collaborate on design and facilitate component validation and procurement
    • Use 3D CAD, Excel, and process simulation software (AnyLogic) to design, build, and test our novel system to capture CO2 at the billions of tons scale
    • Get hands-on to design, build, and test rapid proof of concept prototypes
    • Independently execute on and troubleshoot designs
    • Approach work with open mind and flexibility. You will work in an environment of rapid learning and adjustment


    • We are looking for candidates with different experience levels ranging from entry level to 10+ years of experience.
    • BS / MS in Mechanical or Manufacture Engineering (or equivalent)
    • Experience in process design and material handling, with an emphasis on modularity and scalability
    • You have experience with reactors and other chemical plant equipment
    • In depth knowledge of solids and/or fluid handling and associated equipment
    • A self-starter who is comfortable driving multiple parts of the product design proces s simultaneously
    • Basic understanding of control systems and electronics
    • Ability to track hardware issues, drive root cause investigations, and take corrective actions 
    • Ability to take an analytical approach to problem definition


    • Experience in large assembly shipping, handling, and rigging
    • Experience with plumbing and electrical routing
    • Familiar with construction methods, with an emphasis on modularity
    • Catia, NX, or Solidworks experience
You don’t have to meet 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.

Please note: while we appreciate all applicants, only those chosen for an interview will be contacted by our team.
