About This Role

As a Sr. Software Engineer Fullstack at Solargraf, you'll design and implement scalable microservices and APIs that handle millions of requests daily. You'll work across the stack, from Java/Node.js backends to React/Redux frontends, directly impacting the performance and reliability of solar design tools used globally.

💡 A Day in the Life

Your day starts with a standup to discuss progress on microservices for solar design calculations. You'll spend time coding new features in Java/Spring or Node.js, then shift to building React components for the UI. After lunch, you might review a peer's pull request, debug a production issue, or collaborate with product managers to refine requirements. The day ends with deploying a batch job to process solar data at scale.
