About us

Coperniq is on a mission to revolutionize the renewable energy industry with cutting-edge software solutions. As a Y Combinator-backed startup, funded by Initialized Capital, we’re building the infrastructure for clean energy contractors to succeed. We’re looking for top-tier talent to scale with us.

Role Overview

We’re looking for a Senior Full Stack Engineer to lead the development and scaling of our platform. As a key member of our small, dynamic team, you’ll collaborate across functions to deliver a seamless and powerful experience for our users. This role requires deep expertise in both frontend and backend technologies, as well as a passion for building robust, scalable systems.

If you thrive in fast-paced environments and are excited about making a significant impact in renewable energy, we want to hear from you.
