About The Position

Stand Together is a philanthropic community that helps America’s boldest changemakers tackle the root causes of our country’s biggest problems, from education to the economy, broken communities, and toxic division, among dozens of other pressing issues. We provide our partners with access to resources including funding, thought leadership, a network of peers, and a playbook for applying proven principles to transform lives and society. As a Senior Full-Stack Software Engineer (Front-End Focused) on our Enterprise IT team, you will own the design implementation for the consumer-facing web applications that serve as the front door to Stand Together's philanthropic community. You will build and maintain a Next.js/React TypeScript monorepo, implement production-grade UX and performance, integrate with our OpenAPI backend and headless CMS, and ship via CI/CD to AWS Amplify. The role combines deep front-end engineering, design-system ownership, and operational responsibility for client-side reliability and performance.
