At Envirly x Quantifier, we believe that everyone has a role to play in shaping a more sustainable future — and it all starts with access to clear, actionable data. We specialize in non-financial data analytics, helping companies monitor, report, and understand the environmental impact of their decisions.

We're building Envirly — a modern SaaS platform for ESG reporting, carbon footprint tracking, and climate analytics. Our mission is to show that smart, responsible business transformation can go hand in hand with cost optimization and operational efficiency.

At the same time, we're developing a new, innovative compliance product under the Quantifier — a fresh initiative that addresses the growing regulatory demands and naturally extends our capabilities.

We’re now looking for a Full Stack Developer to help us evolve our tools and take our products to the next level.
