Mechanical Engineer: Biomass Metering

About Charm

Our mission is to reverse climate change and return the atmosphere to 280 ppm CO₂, profitably. We convert waste biomass into carbon-rich bio-oil and inject it into permanent, underground storage as carbon removal, or reform the bio-oil to produce syngas for fossil-free steel.

Our carbon removal pathway took off in 2020 with initial purchases from customers like Stripe, Shopify & Microsoft. In 2021 and 2022 we delivered thousands of tons of carbon removal via off-the-shelf pathways, and also deployed our first R&D prototype pyrolyzer of our own. In the next 18 months, we'll build and deploy the next pyrolyzer revision, demonstrate our fossil-free ironmaking pilot, substantially expand our operations in Colorado and put thousands of tonnes of CO₂e underground.

We're looking to expand our team of ambitious creative and hands-on engineers, fabricators, operators, and forward-thinking humans. We value psychological safety and collaboration. We take calculated risks and don't sweep mistakes under the rug; instead, we pin them to the wall and learn from them. We value that everyone’s unique backgrounds and perspectives shape their work. We encourage you to read our company values.

Come help us reverse climate change. Gigatons or bust!

About the role

Reversing climate change has its share of incredibly difficult problems, and we need the brightest and most creative hardware engineers to help us solve them. Come join Charm’s pyrolysis R&D team, where you will be tasked with solving problems across thermal, fluids and structural design for our pyrolyzers - the machines that produce bio-oil and therefore drive our carbon removal supply!  

We’re building better climate chemical plants - turning them into modular, mobile units that look more like farm equipment, and are made more like cars at scale. Your designs will be put to the test early and often, and constantly push the envelope on what is possible. Best of all, your designs will directly impact our ability to scale our pyrolyzers and put more oil, and therefore more carbon underground. 

We are looking for a Mechanical Engineer to help us design the system that measures our biomass and conveys it into the reactors. This function is critical for our systems’ performance and ultimately tells us how efficiently we are turning waste biomass into sequestered carbon!

Responsibilities

    • Design, build, and test the next iteration of a system that conveys and measures biomass as it enters the reactors.
    • Increase system reliability and safety while accounting for the complexity of handling different types and sizes of biomass, each with different properties and flow characteristics.
    • Identify and creatively reduce risks and increase system accuracy.
    • Hold design reviews with, solicit feedback from, and work closely with the pyrolysis team (we’re a pretty awesome bunch!)
    • Work collaboratively with a wide network of people and resources - this could include managing vendor relationships and timelines, working with external analysis consultants, and working closely with the rest of the pyrolysis team to align development timelines and meet program goals together.

In this role, you will bring

    • A depth of experience in mechanical design
    • A highly hands-on and analytical approach to problem solving
    • A safety-minded design approach
    • Experience working in collaboration with vendors to develop bespoke solutions 
    • 3D modeling experience
    • Effective and highly cross functional communication practices
    • Experience taking designs from prototype to the real deal!

    • You may be a great fit even if you don’t have every skill listed above. We encourage you to apply if you are interested in being a part of our mission!

These skills are a bonus, but not essential:

    • You have worked with augers or other solids conveying equipment
    • You have an understanding of valve assemblies and P&IDs
    • You have an understanding of pyrolysis, gasification, or other thermal conversion processes
This role is located at our San Francisco, CA Minifactory and is not open for remote work. The salary range is $126k-$147k per year, plus benefits described below.

What We Offer

· Stock options
· Medical and dental insurance
