Coperniq

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.

What You’ll Do:

• Design, develop, and maintain scalable and secure full-stack solutions.

• Build and enhance web applications, ensuring a seamless user experience.

• Collaborate closely with product, design, and QA teams to align on requirements and deliver high-quality features.

• Define and implement best practices for software development and deployment.

• Optimize application performance and scalability for growing user demands.

• Mentor junior engineers and contribute to a culture of technical excellence.

• Take ownership of technical decisions and contribute to the product roadmap.

What We’re Looking For:

• Bachelor’s degree in Computer Science, or a related field, with a deep understanding of software engineering principles.

• 7+ years of full-stack development experience, with a balanced skill set across frontend and backend. We are looking for profiles that are not purely frontend or backend — typically a 60/40 split in real project work in either direction.

• Proficient in our tech stack: AWS, React, GraphQL, TypeScript, Node.js, NestJS, MikroORM, PostgreSQL; experience with GitLab for CI/CD, Docker, and Kubernetes.

• Demonstrated experience in designing user interactions on websites, writing server-side API calls, and integrating front-end and back-end aspects of an application.

• Strong problem-solving skills, with a track record of working effectively in a dynamic environment.

• Excellent English skills and the ability to work as part of a team.

• Experience in leading projects, from conception to implementation to feedback integration.

Nice to Have:

• Experience in the renewable energy or SaaS industry.

• Knowledge of geolocation technologies and real-time data integration.

• Familiarity with SOC II compliance and secure development practices.

• Implementing voice agents

• Implementing docs/images editing/annotating with AI

What We Offer:

• A flexible work environment with opportunities for remote work.

• The chance to shape the future of clean energy.

• A collaborative, high-performance team culture.
