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. What unites us is the drive to make complex regulation solvable in a pragmatic, transparent way. We work data-driven and direct, without corporate bureaucracy. Taking ownership, questioning things and moving fast are part of our everyday work.

As a Working Student in Next.js Development, you'll work around 20 hours per week alongside your studies and contribute directly to production features of our platform – not isolated practice tasks. You'll work closely with our development team, have real influence on how features are built, and gain hands-on insight into developing a SaaS product used by international customers.
