## Job description

## About Charm

Our mission is to return the atmosphere to 280 ppm CO₂. We convert excess inedible biomass into carbon-rich bio-oil and inject it into underground storage for permanent carbon removal. At scale, we can use bio-oil to make fossil-free iron.

Our carbon removal efforts began in 2020 with initial purchases from customers like Stripe, Shopify, and Microsoft. Since then, we’ve scaled to thousands of tons of carbon removal, grown to over a hundred employees, and established three locations in San Francisco, Colorado, and Louisiana.

We're expanding our team of ambitious, creative, and hands-on problem solvers. We value psychological safety, collaboration, and continuous learning. We take calculated risks and treat mistakes as opportunities to improve. If you're excited about tackling big challenges, we encourage you to explore our company values.

Come help us reverse climate change. Gigatons or bust!

## Your Responsibilities

- Design unique solutions for our next generation operations pyrolyzer: Develop mechanical and electromechanical systems for production use while considering interfacing systems, operating requirements, operator burden, and regular service and maintenance. Consider what technology needs thorough R&D to simplify and redefine our machine architecture. Learn from previous successes and failures to develop and integrate novel vessels and process steps that tie back to real business needs. Work with our testing team to validate performance before operations integration.

- Conduct thorough engineering analysis: Work with process engineers to develop thermal and flow models to inform system design. Process piping and vessels are important components in our greater pyrolysis system, refine their mechanisms to deliver an industrial solution.

- Troubleshoot and resolve issues: Identify and troubleshoot mechanical system malfunctions and performance gaps. Determine why a failure mode is observed and implement a corrective action to return the system to optimal performance.

- Develop and execute test plans and commissioning campaigns for production hardware: Take direct ownership of your designs beyond pressing print on your drawings. Validate performance before and after machine installation.

- Collaborate with cross-functional teams: Work closely with electrical engineers, software developers, and other mechanical engineers to implement mechanical systems into the larger pyrolysis package

- Support on-call production support as needed, if our frontline Engineering Technician group needs help solving critical Operations problems

You Bring

- Bachelor’s degree in Mechanical Engineering, or a related field

- Seasoned mechanical design experience (5-8 years)

- CAD knowledge is a must, we use OnShape

- Experience reviewing and releasing detailed fabrication and assembly drawings with a high attention to detail and strong configuration control practices

- Skilled in modes of heat transfer, sensor and actuator selection for robust operations, and building project requirements from ambiguity

- Skilled with basic fabrication techniques and the design principles around them

- Familiarity with piping standards, flange interfaces, gasket selection, and mechanical integration of process systems.

- Hands-on mechanical troubleshooting and assembly experience

- A strong willingness to get your hands dirty and intimately interact with all pyrolysis system components

- Documentation skills that demonstrate your thought process and design process when making improvements

- Skilled with electromechanical systems and design for material handling, think conveyors, pumps, and blowers

- Experience designing mechanical weldment under load and process pressure

- A desire to work alongside Electrical & Controls Engineers and fabricators to turn solutions into physical, installed hardware as quickly as possible. Use quick implementation skills to make quick and long-term fixes to the pyrolysis system in service of system improvement.

- Ability to communicate priorities, system progress, and work cross functionally

- Hands-on mechanical troubleshooting and assembly experience

- An excitement for scaling up hardware that has the potential to positively impact climate change!

Bonus, if You Bring

- A Masters degree in Mechanical Engineering, or a related field

- Onshape modeling experience

- Experience with process piping and vessel design in high-temperature or industrial environments

- Design of operations facing industrial equipment

-

## About Charm Industrial

## Company Overview
- **One-liner**: Charm Industrial removes carbon dioxide from the atmosphere by converting agricultural and forest biomass into a carbon-rich liquid (bio-oil) and injecting it deep underground for permanent storage.
- **Entity Type**: Private (Series B, raised $100 million)
- **Headquarters**: San Francisco, California, United States
- **Founded**: 2018
- **Founders**: Peter Reinhardt (CEO & Founder), and other co-founders including the Chief Scientist who had the breakthrough to sequester bio-oil in 2020.

## Core Business
- Primary industry/industries: Carbon Removal, Climate Tech, Environmental Services
- Target customers: Enterprise (tech companies, financial institutions, etc. looking to offset their carbon footprint)
- Mission or purpose statement: "Charm is working to return the atmosphere to 280 ppm CO₂."  The company uses plants to capture CO₂ from the atmosphere, converts the biomass into a stable, carbon-rich liquid, and then pumps it deep underground for permanent removal.

## Products & Services
- **Carbon Removal via Bio-Oil Sequestration**: Charm's core service. The company collects cellulosic biomass (agricultural residues) after harvest, processes it through mobile fast pyrolyzers to create a stable, carbon-rich bio-oil, and then injects this bio-oil into EPA-regulated injection wells. The bio-oil sinks and solidifies in place for permanent storage.
- **Biochar**: Charm's pyrolysis process also produces biochar as a co-product.
- **Carbon Removal Credits**: Charm sells verified carbon removal credits to enterprises and organizations. Customers include Stripe, Shopify, JP Morgan, and Microsoft.

## Market Standing
- **Valuation/Market Cap**: Not publicly disclosed.
- **Key Metric**: Total Funding of $145.5 million (6 prior funding rounds). Annual Revenue of $9 million.
- **Notable Investors/Partners**: General Catalyst (led Series B), Lowercarbon Capital, Prime Coalition, Valor Equity Partners, Incite Ventures.
- **Growth Signals**: The company has completed over 7,200 tons of CO₂ Equivalent removal. They have built a transparent ledger and verification model for the industry. They are expanding capacity and co-benefits through enterprise purchases and long-term offtakes.

## Competitive Advantages
- **Proprietary Technology**: Charm designs, builds, and operates a fleet of mobile fast pyrolyzers. This is a core differentiator, allowing them to process biomass on-site.
- **Permanent Storage**: The bio-oil is injected underground where it sinks and solidifies, ensuring permanent carbon removal, unlike some other methods that are susceptible to reversal.
- **Established Track Record**: The company has completed thousands of tons of carbon removal for high-profile customers like Stripe, Shopify, JP Morgan, and Microsoft.
- **Transparency**: Charm leads the industry with a transparent ledger and a verification model that reduces the risk of over-crediting.

## Strategic Focus
- **Scaling Capacity**: Increasing the number of pyrolyzers and injection sites to meet growing demand for carbon removal credits.
- **Decarbonizing Steel**: At scale, Charm's bio-oil can be used to reduce iron ore into metallic iron, helping to decarbonize industrial emissions from steelmaking.
- **Community Impact**: Charm partners with communities to create new jobs, reduce wildfire risk, improve air quality, and safely close abandoned oil wells.
- **Expanding Product Lines**: Developing new markets for biochar and other co-products.

## Why Work Here
