Senior Fullstack Engineer

We’re building Firesale — a platform where sellers create AI-powered listings by simply recording a video. Buyers see beautiful, interactive posts generated automatically. It’s fast, visual, and redefines how products are presented and discovered.

Everything is built from scratch with a modular, service-oriented architecture using NestJS and NextJS.
