Climate Software Engineer Intern

About CarbonMarketsHQ

We're building the infrastructure for high-integrity carbon markets. CarbonMarketsHQ develops carbon removal and avoidance projects alongside the technology solutions needed to audit, trace, and monitor every tonne of carbon removed. We're not just talking about climate action – we're building the tech that makes it transparent, verifiable, and scalable.

What You'll Be Building

You'll be one of the lead developers on our Biochar dMRV (Monitoring, Reporting, Verification) platform – think of it as creating a complete supply chain tracking system for carbon removal projects. From the moment biomass is collected to when biochar gets applied to soil, every step needs to be tracked, verified, and auditable by third parties.

This isn't your typical CRUD app. You'll be working with:

• GPS tracking and mapping for feedstock sourcing and application sites
• Real-time IoT data from pyrolysis equipment
• Laboratory integrations for quality testing
• Chain of custody systems with immutable records
• Complex carbon accounting calculations
• Third-party verification workflows

Tech Stack

• Python - FastAPI backend, data processing, integrations
• JavaScript/React - Frontend dashboard and mobile-friendly interfaces
• FastAPI - API development and real-time data handling
• PostgreSQL - Complex relational data with geospatial extensions
• Azure/AWS Cloud Services

What Makes This Different

• Vibe coding is totally fine – we care more about shipping working solutions than perfect architecture on day one
• AI coding tools are a must – we expect you to be productive with Claude code, Cursor, GitHub Copilot, etc. If you're not using AI to code faster, you're behind
• Real impact – the code you write directly enables carbon removal projects to get verified and funded
• Small team – your work matters immediately, no bureaucracy or endless meetings

Before You Apply - Answer These:

1. Technical Screening:

• Have you built a full-stack application with user authentication and database integration? (Share GitHub link)
• Rate your comfort level with Python backend development (1-10) and give a specific example
• What's your experience with React? Any projects where you handled forms, state management, or API integration?

2. AI Tools & Approach:

• Which AI coding tools do you currently use and for what?
• How do you typically approach building a new feature you've never built before?

3. Climate/Impact:

• Why does working on climate tech matter to you personally?
• Have you worked on any projects (personal/school/work) related to environmental data, mapping, or supply chain tracking?

What You'll Learn

• Carbon Markets Industry - carbon markets, MRV systems, verification protocols
• Enterprise software - building systems that handle real money and regulatory compliance
• Full-stack development - from PostgreSQL optimization to React UX design
• Product thinking - balancing user needs with technical constraints in a regulated industry
