Senior Full-Stack Developer (Next.js)

This role is about taking end-to-end ownership of a high-traffic D2C platform that serves hundreds of thousands of customers globally. The product is well beyond MVP and is scaling rapidly, so the engineer will shape architecture, improve reliability, and mentor junior developers. Daily work involves both frontend and backend development using Next.js, React, TypeScript, PostgreSQL, Redis, and cloud infrastructure (AWS/Cloudflare), with a focus on performance, scalability, and product quality. It's a senior role for someone who enjoys solving hard problems under real-world pressure and wants to help build a world-class engineering organization.
