How to Apply for Full Stack Software Engineer
at Reunion
🏢 About Reunion
Reunion is accelerating clean energy investments through a specialized tax credit marketplace, positioning itself at the intersection of technology and sustainability. The company offers the unique opportunity to work on meaningful climate solutions while building complex financial technology products in a remote-first environment.
About This Role
This Full Stack Software Engineer role involves building and maintaining both the serverless backend (using AWS services and Serverless Framework) and the frontend (with Next.js, React, and TypeScript) for Reunion's tax credit marketplace. The position is impactful because you'll be creating proprietary compliance databases through data scraping and exploring AI automation for audit processes, directly supporting the company's mission to accelerate clean energy investments.
💡 A Day in the Life
A typical day might involve collaborating with cross-functional teams to design new features, implementing serverless backend services using AWS Lambda and RDS, developing frontend components with Next.js and React, and working on data scrapers to build proprietary compliance databases. You'd likely participate in code reviews, advocate for engineering roadmap items, and explore automation opportunities using AI agents for audit processes.
