at Carbon Re

🏢 About Carbon Re

Carbon Re is at the forefront of using AI to tackle one of the hardest climate challenges: decarbonizing heavy industries like cement and steel, which together produce ~15% of global CO2 emissions. Their mission is to cut gigatonnes of carbon annually, and they're building a culture around 'high bar, concrete honesty, autonomous ownership, kindness and fun.'

About This Role

This General Application is an open call for exceptional talent across engineering, ML, product, commercial, and operations to join a mission-driven team. You'll work on SaaS products that help heavy industry optimize operations in real time, directly reducing costs and carbon emissions. The role offers the chance to be part of the next industrial revolution from day one.

💡 A Day in the Life

As a remote team member, your day might start with a async standup on Slack, followed by deep work on your domain—whether coding a model, analyzing plant data, or talking to customers. You'll have autonomy to set your schedule, with regular cross-functional syncs to align on priorities. The work is varied and fast-paced, with the constant reminder that your output directly contributes to cutting emissions at scale.

  • You thrive in a fast-paced startup environment and are excited to build the foundation for a new industrial era.

📝 Tips for Applying to Carbon Re

1

Tailor your resume and cover letter to highlight specific experience with heavy industry, manufacturing, or climate tech—generic applications won't stand out.

2

Explicitly address how you align with each of the four operating principles (high bar, concrete honesty, autonomous ownership, kindness and fun) with concrete examples.

3

If you're an engineer or ML specialist, showcase projects where you optimized complex systems (e.g., industrial processes, energy systems) using AI or data-driven approaches.

4

For product or commercial roles, demonstrate your understanding of the cement/steel industry's challenges and how SaaS can drive adoption and impact.

5

Include measurable impact in your past work—Carbon Re cares about gigatonne-scale results, so quantify your contributions in terms of CO2 reduction, cost savings, or efficiency gains.

✉️ What to Emphasize in Your Cover Letter

['Explain why you are specifically passionate about decarbonizing heavy industry (cement, steel, glass) and how your skills directly contribute to that mission.', "Provide concrete examples of how you've demonstrated the four operating principles in your career (e.g., 'I once owned a project from conception to delivery, setting a high bar for quality').", 'Highlight your ability to work autonomously in a remote environment and your comfort with ambiguity in a startup.', 'Show that you understand the scale of the problem and are excited by the challenge of cutting gigatonnes of CO2.']

🔍 Research Before Applying

To stand out, make sure you've researched:

  • → Read Carbon Re's blog and case studies to understand their current product offerings and technology stack (e.g., their AI models for cement kilns).
  • → Study the basics of cement and steel manufacturing processes—understand key emission sources like clinker production and blast furnaces.
  • → Look into the competitive landscape: other climate tech startups (e.g., Boston Metal, Sublime Systems) and how Carbon Re differentiates.
  • → Review the company's LinkedIn and team page to get a sense of the culture and backgrounds of current employees.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 How would you approach reducing emissions in a cement plant using AI? Walk through the data, models, and deployment challenges.
2 Describe a time you had to balance technical excellence with speed to impact. How did you decide?
3 What does 'concrete honesty' mean to you in a team setting? Give an example of a time you practiced it.
4 How do you prioritize tasks when you have autonomous ownership of a project with competing demands?
5 How would you explain the value of Carbon Re's product to a skeptical plant manager focused on cost?

⚠️ Common Mistakes to Avoid

  • Don't submit a generic application that doesn't mention heavy industry or climate impact—Carbon Re is mission-driven and looks for genuine passion.
  • Avoid exaggerating your experience; the company values 'concrete honesty' and will see through fluff.
  • Don't neglect to show how you work autonomously—this is a remote role, and they need self-starters who don't require constant direction.
