at Bank.Green
🏢 About Bank.Green
Bank.Green is a unique climate advocacy NGO that empowers bank customers to drive sustainable lending and decarbonize the banking sector through direct consumer action. Unlike traditional environmental organizations, they focus specifically on the financial sector's climate impact, making them a targeted force for change. Working here means contributing to tangible climate action while leveraging technology to influence major financial institutions.
About This Role
This part-time Senior Fullstack Engineer role involves building frontend features that help users understand and act on bank climate data, while maintaining and improving an Astro/React codebase with a focus on performance and maintainability. You'll collaborate on architectural decisions with another senior engineer and help establish sensible frontend and deployment patterns. The role is impactful because your technical work directly enables users to make climate-conscious banking decisions that pressure financial institutions toward decarbonization.
💡 A Day in the Life
A typical day might involve collaborating with the other senior engineer on architectural decisions for new frontend features, implementing performance improvements to the Astro/React codebase, and reviewing pull requests while helping establish sensible frontend patterns. You'd balance building new features that help users understand bank climate data with maintaining the existing codebase for long-term clarity and efficiency.
