Working Student (m/f/d) Full-Stack Developer - Next.js

We are CBAM Estimator – a young SaaS company based in Stuttgart. Our mission is to help companies meet the requirements of the EU Carbon Border Adjustment Mechanism (CBAM) correctly, efficiently and at scale. To do this, we build modern web platforms that let our customers analyze the impact, obligations and costs of CBAM and estimate them realistically. Our customers include international industrial and trading companies that rely on accurate data, clean processes and planning certainty. We are a young, international team with diverse backgrounds – from IT, emissions calculation and mathematics to business.
