Senior Full Stack Developer

Overview We’re looking for a senior, hands-on Full Stack Developer with strong PHP backend experience and solid modern frontend skills. This person will work on an existing production application spanning PHP, PostgreSQL, TypeScript, Alpine.js, SCSS, and external API integrations. You should be comfortable working across the entire request lifecycle—from browser interactions and server-rendered templates through controllers, services, database models, and third-party APIs. This is not a role for someone who only builds APIs or only works in React. We need an experienced developer who can understand an existing application, diagnose problems across the stack, make sound technical decisions, and ship production features independently. You’ll work on business-critical applications that support guided workflows, capture and process data, and integrate with external systems and services.
