🏢 About Renewable Energy Systems
Renewable Energy Systems is a global leader in clean energy development with an ambitious goal of adding 22 GW of new capacity in the next five years. Working here means contributing directly to combating climate change through technology, with the company's mission-driven focus making it unique in the energy sector. The Larne, Northern Ireland location offers the opportunity to work on cutting-edge renewable energy projects while being part of a growing tech team in a scenic coastal region.
About This Role
This Software Developer role focuses on maintaining and enhancing Python-based tools that support renewable energy innovation, specifically working on the Innovation Tools suite that helps optimize clean energy projects. You'll be applying software engineering best practices to both legacy systems and new development, with opportunities to influence technical direction. The role directly impacts the company's ability to scale renewable energy solutions globally through improved internal tooling.
💡 A Day in the Life
A typical day involves collaborating with energy analysts and engineers to understand their tool needs, then implementing improvements to existing Python tools or developing new features for the Innovation Tools suite. You'll spend time writing and reviewing code, setting up automated tests, and deploying updates through CI/CD pipelines, all while ensuring your work supports the company's renewable energy objectives. Regular team discussions about technical direction and how to optimize tools for global clean energy projects would be common.
