Modeling and Simulation Engineer

San Francisco, CA /

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 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 for dedicated and driven modeling and simulation engineers to help us design, optimize, and build our carbon removal process. We are specifically looking for someone with experience in both computational fluid dynamics, as well as kinetic modeling. Further, the team will be responsible for techno-economic and life cycle analysis for the overall process system. These models will be continuously iterated and updated with input from both the research and engineer teams. As we scale, you and your team will help inform design optimization via iterative modeling and simulation.

What You Will Do

    • Lead modeling and simulation efforts for Heirloom’s carbon removal process. 
    • Coordinate modeling with individual team members, the research team, and the engineering team.
    • Develop integrated modeling to evaluate fluid dynamics, heat transfer, and reaction kinetics, including any parasitic effects that may occur, for major process steps. 
    • Incorporate measured data from developmental testing of systems and processes in the laboratory into modeling environment.
    • Define simulations to meet systems and process engineering needs and support iterative systems development and verification.
    • Develop and manage data flow through models and simulations.
    • Summarize model and simulation activities.

Minimum Qualifications

    • ≥ 5 years of relevant work experience in an applied field with expertise in modeling and simulation, specifically related to computational fluid dynamics and reacting thermal-fluid systems. 
    • Bachelor's degree in Engineering (such as Chemical, Mechanical, or Process engineering, or a related field), Applied Science (Geology, Chemistry, Physics, or related field) or equivalent practical experience.
    • Knowledge of and experience with computational fluid dynamics softwares (ANSYS, COMSOL, Autodesk, or similar). Additional experience with reacting thermal-fluid systems is preferred. 
    • Experience with critical problem solving and complex engineering systems. 
    • Previous experience in high output teams

Desired Qualifications

    • Advanced degree involving model development and simulation. 
    • Knowledge of and experience performing both techno-economic and life cycle analyses based on process data. 
    • Experience or familiarity with cement production technologies, such as calcination, and their modeling and simulation.
    • Experience in kinetic simulation with direct reference to carbon mineralization technologies.
    • Knowledge of the landscape for carbon removal technologies
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.

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